Botswana’s SEZ policy integrates critical elements that align with the country’s Vision 2036 objectives. These elements focus on creating a sustainable and diversified economy by promoting industrialization, enhancing infrastructure, and reforming regulations to attract investment and drive economic growth.

The diagram below illustrates the interplay between the SEZ policy components and their contribution to Botswana’s Vision 2036 objectives:

The conceptual framework ( Figure 1 ) visually represents the relationship between Special Economic Zone (SEZ) policy components and their contribution to achieving Botswana’s Vision 2036 objectives. This framework captures the dynamic interplay of critical policy components—industrialization, infrastructure development, and regulatory reforms—and links them to intended socio-economic outcomes, such as economic diversification, foreign direct investment (FDI) growth, and job creation.

A core pillar of the SEZ policy is industrialization. The aim is to diversify Botswana’s economy, traditionally dependent on mining, by developing a robust industrial base in sectors such as iron and steel production, agro-processing, pharmaceuticals, textiles, and garments ( Republic of Botswana, 2021 ). This aligns with Vision 2036’s goal to transition Botswana into a high-income economy, leveraging value addition and beneficiation to create jobs and enhance productivity.

The industrialization component of SEZ policies plays a pivotal role in fostering economic diversification. By promoting value addition and creating industry-specific zones, SEZ policies aim to transition Botswana’s economy from being resource-dependent to a knowledge-based and diversified economy ( AfDB, 2021 ). Industrial clusters within SEZs facilitate the development of non-traditional sectors like manufacturing, agro-processing, and technology, aligning with Vision 2036’s goal of reducing reliance on diamond mining ( Republic of Botswana, 2016 ).

Infrastructure is a critical enabler of SEZ success. Botswana’s SEZ policy emphasizes developing logistics, transportation, and utilities to enhance connectivity and attract both domestic and international investors. For example, the Selebi-Phikwe SEZ includes advanced infrastructure to support industrial activities. This mirrors international examples like Singapore’s SEZs, where world-class infrastructure has driven competitiveness and innovation ( Zeng, 2015 ).

Infrastructure development is another cornerstone of SEZ policies. The provision of world-class infrastructure, such as transportation networks, power supplies, and ICT systems, enhances connectivity and reduces operational bottlenecks for businesses ( World Bank, 2020 ). This infrastructure not only supports the competitiveness of SEZs but also improves the broader investment climate in Botswana, attracting multinational corporations and fostering sustainable economic growth.

Simplified regulations and business-friendly policies are key aspects of Botswana’s SEZ strategy. Measures include streamlined business registration processes, tax incentives, and investment protections to create a conducive environment for businesses. Such reforms are critical to removing barriers to entry, enhancing the ease of doing business, and attracting foreign direct investment (FDI). Similar regulatory reforms in countries like the United Arab Emirates (e.g., Dubai’s Jebel Ali Free Zone) have been instrumental in attracting global investors and driving economic diversification ( Aggarwal, 2012 ).

Effective regulatory frameworks are essential for creating a conducive environment for investment and operations within SEZs. By streamlining bureaucratic processes, offering tax incentives, and ensuring legal transparency, SEZ policies reduce the cost of doing business and enhance investor confidence ( UNCTAD, 2022 ). These reforms directly support Vision 2036’s goal of positioning Botswana as an attractive investment destination in the global market.

The outcomes of economic diversification, FDI growth, and job creation—are interconnected and mutually reinforcing. For example, infrastructure improvements attract FDI, which in turn stimulates industrial activity and creates jobs. These outcomes contribute to inclusive and sustainable economic growth, a fundamental aspiration of Vision 2036 ( Republic of Botswana, 2016 ).

The conceptual framework underscores the need for a coordinated approach in SEZ policy design and implementation. By ensuring alignment between policy components and national objectives, Botswana can leverage SEZs as catalysts for long-term socio-economic transformation. Moreover, the framework highlights the critical role of monitoring and evaluation mechanisms to assess policy effectiveness and make evidence-based adjustments.

Empirical evidence highlights the transformative role of Special Economic Zones (SEZs) in fostering economic growth, industrialization, and job creation across different regions. Studies from Asia, Europe, America, Africa, and Botswana reveal the varied outcomes and methodologies associated with SEZ implementation, providing valuable lessons for policymaking.

In China, the Shenzhen SEZ, established in 1980, exemplifies the success of SEZs in catalyzing economic transformation. Shenzhen evolved from a small fishing village to a global manufacturing hub, achieving an average annual GDP growth of 22% from 1980 to 2018. Key to this success were incentives for foreign direct investment (FDI), deregulation, and export-driven policies ( World Bank, 2018 ). This highlights how strategic policy interventions can leverage SEZs for economic development.

India’s SEZs also demonstrate the effectiveness of these zones in driving industrialization. Aggarwal (2012) used a difference-in-differences model to assess the impact of SEZs between 2000 and 2006, revealing that SEZs contributed 18% of India’s total exports, with significant growth in sectors like information technology and textiles. Similarly, Vietnam’s SEZs attracted 60% of national FDI between 2005 and 2015, fostering manufacturing growth in high-value sectors such as electronics ( Pham & Vu, 2017 ).

Malaysia’s Penang SEZ emerged as a technology-intensive hub between 1990 and 2010, contributing 40% of the country’s electronics exports ( ADB, 2015 ). Strong infrastructure and integration into global value chains were key factors in attracting multinational corporations and boosting industrial capacity. Similarly, South Korea’s Incheon Free Economic Zone saw a 50% increase in FDI inflows by 2015, spurring growth in logistics and advanced manufacturing sectors ( OECD, 2018 ).

In Europe, SEZs have been instrumental in reducing regional disparities. For example, Polish SEZs increased regional GDP by 12% between 2004 and 2014, attracting investment to underdeveloped areas and fostering economic diversification ( Jedrzejczyk, 2020 ). Ireland’s Shannon SEZ, established in 1959, became a global technology hub by 1995, attracting 70% of new FDI in technology, demonstrating the power of fiscal incentives and access to European markets ( IDA Ireland, 2017 ). Spain’s Canary Islands SEZs saw exports increase by 200% from 2005 to 2015, highlighting the effectiveness of tax incentives and efficient logistics ( UNCTAD, 2019 ).

Russia’s Kaliningrad SEZ focused on energy and manufacturing, with exports increasing by 35% from 2000 to 2010, illustrating the role of targeted investment policies in leveraging strategic geographic advantages ( OECD, 2012 ).

In the Americas, SEZs have played a crucial role in integrating regional economies into global supply chains. Mexico’s Maquiladoras contributed 30% of national exports between 2000 and 2010, capitalizing on proximity to the U.S. market and low labor costs ( Wilson & Gallagher, 2015 ). Similarly, Brazil’s SEZs led to a 20% increase in employment in the Amazonas region between 2005 and 2015, primarily in manufacturing ( Barros et al., 2018 ). Colombia’s SEZs saw a 15% annual increase in FDI between 2008 and 2018, supporting regional economic integration ( Ardila-Gomez, 2020 ).

Africa presents a mixed picture, with some SEZs showing significant success. Rwanda’s Kigali SEZ attracted $100 million in FDI by 2020 and created over 8000 jobs, aided by consistent policies and infrastructure investments ( UNCTAD, 2022 ). Ethiopia’s Hawassa Industrial Park demonstrated the potential of sectoral specialization, increasing textile exports by 150% between 2015 and 2020 and providing 35,000 jobs ( ADB, 2019 ). South Africa’s Coega Industrial Development Zone led to a 20% increase in automotive exports between 2002 and 2018, showcasing the effectiveness of targeted sectoral policies ( DTI South Africa, 2019 ).

Nigeria’s SEZs also contributed to job creation, with 50,000 jobs annually between 2005 and 2015, particularly in agro-processing and light manufacturing ( Akinci & Crittle, 2008 ). Kenya’s SEZs boosted FDI inflows, contributing 30% of national FDI between 2010 and 2020, fostering export-oriented growth, especially in the horticulture and textiles sectors ( Njeru et al., 2016 ). Egypt’s Port Said SEZ reported a 25% annual growth in exports between 2010 and 2017, driven by sectoral policies and robust logistics infrastructure ( UNIDO, 2018 ).

Empirical data on Botswana’s SEZs is limited, but preliminary studies show significant potential. The Gaborone SEZ has attracted investments in logistics and trade, although infrastructural and policy gaps hinder full utilization ( BOCCIM, 2021 ). Aligning Botswana’s SEZ policies with best practices from regions such as Asia and Europe could enhance their contribution to Vision 2036 objectives. Targeted sectoral policies, improved infrastructure, and regulatory support could position Botswana’s SEZs as key drivers of industrialization and economic diversification.

In conclusion, the global success of SEZs highlights the importance of tailored policies, infrastructure, and consistent governance. By learning from international experiences, Botswana can optimize its SEZs for sustainable growth, industrialization, and long-term economic development.

A systematic review is a comprehensive research method used to synthesize existing evidence on a specific topic, ensuring transparency, rigor, and objectivity. This methodology is especially valuable in policy analysis, allowing researchers to assess the impact of initiatives like Special Economic Zones (SEZs) on economic growth. This study evaluates Botswana’s SEZ policy’s economic contributions, particularly to foreign direct investment (FDI), employment, industrial output, and GDP growth, by following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines ( Moher et al., 2009 ). Using this framework ensures a structured and replicable review process, minimizing bias and enhancing the reliability of findings ( Higgins et al., 2011 ). By consolidating various theoretical and empirical studies, this systematic review contributes valuable insights for policymakers and stakeholders interested in optimizing SEZ policies for sustainable growth ( Zeng, 2015 ).

The study employs a systematic review approach with a qualitative synthesis of existing empirical and theoretical literature on Botswana’s SEZ policy. Systematic reviews offer a transparent, comprehensive, and rigorous method for summarizing existing research ( Tranfield, Denyer, & Smart, 2003 ). The review focuses on Botswana’s SEZs and their impact on national economic indicators, such as FDI, employment, industrial output, and GDP growth, providing a holistic view of their contribution to the country’s industrialization.

A comprehensive search of the literature was conducted using databases like Scopus, Web of Science, Google Scholar, and JSTOR, as well as reports from the Botswana Investment and Trade Centre (BITC), World Bank, IMF, and Botswana SEZ Authority (SEZA). Keywords such as “Special Economic Zones in Botswana,” “economic impact of SEZs in Botswana,” and “SEZs and national economic growth” were used, with Boolean operators to refine results ( Snyder, 2019 ). The review focused on studies published between 2000 and 2023 to ensure both historical context and recent performance assessments of Botswana’s SEZ policy.

To ensure relevance and rigor, the study adhered to strict inclusion and exclusion criteria:

Data extraction involved systematically collecting information from the selected studies using a standardized form. Key details extracted included author(s), publication year, methodology, and findings on the economic impact of SEZs. Thematic analysis was used to categorize findings into primary themes such as:

The credibility of the selected studies was ensured through the application of the Critical Appraisal Skills Programme (CASP) checklist ( CASP, 2018 ). This checklist assessed studies based on:

Findings were categorized into four key thematic areas:

1) Investment Inflows: FDI trends in Botswana’s SEZs were analyzed based on reports from BITC and the World Bank, with comparisons to regional SEZs like South Africa’s Coega SEZ.

2) Employment Generation: The contribution of SEZs to job creation and sectoral employment shifts, particularly in manufacturing and logistics, was assessed.

3) Industrial Output and GDP Contribution: SEZs’ role in national GDP growth and sector-specific contributions, particularly in export-oriented industries, was examined using Botswana’s government economic reports.

4) Challenges and Policy Gaps: Barriers to SEZ performance, such as regulatory inefficiencies and infrastructure deficits, were identified, with recommendations drawn from successful SEZ models in other emerging economies ( Zeng, 2016 ).

The study adhered to ethical standards by ensuring the credibility and accuracy of selected sources. Peer-reviewed and official materials were prioritized to enhance the reliability of the findings ( Creswell, 2014 ). Proper citation of all sources was ensured, maintaining academic integrity and transparency ( Pears & Shields, 2019 ). The study also emphasized impartiality, ensuring that findings were not biased toward positive outcomes of SEZs, but rather reflected a balanced assessment of all available evidence ( Merriam & Tisdell, 2015 ).

Despite the systematic methodology, several limitations could influence the comprehensiveness of the findings:

Despite these limitations, the study mitigated these gaps by integrating regional studies and government reports to provide a broader understanding of SEZ performance in Botswana.

In conclusion, the systematic review methodology used in this study provides a comprehensive, rigorous assessment of Botswana’s SEZ policy’s economic impact. By synthesizing a wide range of empirical studies and policy reports, the review identifies key contributions of SEZs to FDI, employment, industrial output, and GDP growth, while also highlighting challenges such as regulatory inefficiencies and infrastructure gaps. Despite limitations such as the lack of recent data and publication bias, the study offers valuable insights for policymakers and stakeholders looking to optimize Botswana’s SEZ strategy for enhanced economic development.

Foreign Direct Investment (FDI) in Botswana’s SEZs has seen both progress and stagnation, with notable success in some sectors but slower growth in others. According to the Botswana Investment and Trade Centre (BITC), SEZs in Gaborone and Francistown have attracted significant foreign capital, particularly in logistics, agro-processing, and light manufacturing ( BITC, 2023 ). The World Bank (2022) reports that Botswana’s SEZs contributed around 15% of total FDI inflows in 2021, with China, India, and the European Union being the primary investors.

While this represents a positive trend, comparative insights from other regional SEZs suggest room for improvement. Botswana’s SEZs, for example, lag behind South Africa’s Coega SEZ and Kenya’s Mombasa SEZ in attracting high-tech industries such as automotive manufacturing and renewable energy ( Farole & Akinci, 2011 ). However, Botswana excels in offering favorable tax incentives and a higher ranking on the World Bank’s Ease of Doing Business Index ( World Bank, 2023 ), which may help attract further investments in more high-tech industries like AI-driven manufacturing and blockchain-integrated logistics.

When compared to regional counterparts such as Rwanda and Ethiopia, which have experienced rapid growth in high-tech sectors like renewable energy and AI-driven manufacturing, Botswana’s SEZs remain underutilized in these emerging industries. Rwanda’s SEZ success can largely be attributed to its streamlined regulatory framework, strong public-private partnerships, and targeted investments in digital infrastructure, which have fostered an enabling environment for innovation-driven industries ( UNECA, 2021 ). Ethiopia, on the other hand, has leveraged state-led industrial policies and preferential trade agreements, particularly with China, to enhance SEZ attractiveness for foreign investors in textile and light manufacturing ( Gebreeyesus, 2020 ).

1) Governance and Policy Frameworks

One of the key factors distinguishing successful SEZ models is the efficiency of their governance structures and policy frameworks. Rwanda’s Kigali Special Economic Zone (KSEZ) has benefited from a one-stop service center that expedites business registration, customs clearance, and investment approvals, significantly reducing bureaucratic delays ( World Bank, 2021 ). In contrast, Botswana’s SEZs have faced administrative bottlenecks, with investors citing regulatory uncertainty and delays in obtaining permits as major barriers to entry ( BIDPA, 2023 ). Streamlining regulatory processes and adopting a centralized SEZ governance model, similar to Rwanda’s, could enhance Botswana’s SEZ performance.

2) Sectoral Focus and Industry Specialization

Successful SEZs tend to specialize in industries where they have a comparative advantage. Ethiopia’s industrial parks have become global hubs for textile manufacturing due to their integration into global value chains, supported by preferential trade agreements under the African Growth and Opportunity Act (AGOA) ( Gebreeyesus, 2020 ). Similarly, Kenya’s Konza Technopolis SEZ is emerging as a digital innovation hub by attracting multinational tech firms through tax incentives and investment in digital infrastructure ( Gachanja, 2022 ). Botswana, despite its strong financial sector and diamond value chain, has not fully capitalized on high-tech industries such as AI-driven manufacturing and blockchain-based logistics, which have gained traction in competing SEZs. Strategic diversification into these sectors, along with incentives to attract tech-based FDI, could improve Botswana’s SEZ competitiveness.

3) Infrastructure and Investment Climate

Infrastructure development plays a crucial role in SEZ success. Rwanda has invested heavily in renewable energy and smart infrastructure, ensuring reliable electricity and internet connectivity within its SEZs ( UNECA, 2021 ). Ethiopia’s investment in railway and port connectivity has enhanced trade efficiency, reducing logistics costs for SEZ-based exporters ( World Bank, 2021 ). By contrast, Botswana’s SEZs still face infrastructure gaps, particularly in transport and digital connectivity, which limit their attractiveness to global investors ( BIDPA, 2023 ). Strengthening transport networks and digital infrastructure, alongside policies that lower the cost of doing business, would enhance the competitiveness of Botswana’s SEZs.

4) FDI Attraction and Incentive Structures

The ability to attract foreign direct investment (FDI) is a defining feature of successful SEZs. Rwanda’s SEZs have benefited from a highly transparent incentive regime, offering competitive tax breaks, customs exemptions, and clear investment protection policies ( UNECA, 2021 ). Ethiopia’s model, though state-driven, has successfully leveraged long-term lease agreements and subsidized industrial land to attract Chinese and Turkish investors ( Gebreeyesus, 2020 ). In contrast, Botswana’s SEZ incentive structure is less competitive, with investors noting concerns about high operational costs and less aggressive FDI promotion compared to regional counterparts ( BIDPA, 2023 ). Adopting more competitive incentive packages and strengthening Botswana’s SEZ investment promotion strategy could significantly enhance FDI inflows.

Botswana’s SEZs have played a crucial role in job creation, contributing to the national employment agenda. According to national labor statistics, over 35,000 jobs have been created since the inception of SEZs, with the majority of these jobs arising in the manufacturing (45%), logistics (30%), and agro-processing (15%) sectors ( Statistics Botswana, 2023 ). While these figures demonstrate the effectiveness of SEZs in stimulating employment, they also reveal the changing nature of work within these zones, especially with the rise of automation and AI integration.

The integration of AI and automation into Botswana’s SEZs has led to significant shifts in employment patterns. AI-driven technologies, such as machine learning algorithms in manufacturing, have increased production efficiency by 20% but reduced manual labor needs by 12% ( McKinsey, 2023 ). This trend is particularly noticeable in the logistics sector, where robotic process automation (RPA) has reduced the demand for low-skilled manual labor. Consequently, there is a growing demand for tech-savvy workers skilled in AI, data analytics, and robotics, creating a need for robust reskilling programs to equip the labor force with the necessary skills ( ILO, 2023 ).

The shift towards a more technology-driven workforce highlights the importance of reskilling and upskilling programs. The growing reliance on AI and robotics means that manual labor is being replaced by higher-skilled jobs, leading to job polarization. This issue could potentially widen the income gap if workers are unable to transition into new roles that demand advanced technological expertise. There is a clear need for Botswana to invest in skills development programs that focus on data analytics, machine learning, and robotic process automation to ensure that workers in SEZs are prepared for the jobs of the future.

Botswana’s SEZs have demonstrated a solid contribution to the national economy, currently accounting for approximately 7% of the nation’s GDP, with projections indicating that this figure could rise to 12% by 2030 ( Botswana Economic Outlook, 2023 ). This growth is primarily driven by the expansion of AI-driven industrial policies and the influx of FDI in technology-enabled sectors. The major economic drivers within the SEZs include the export of high-value processed minerals, renewable energy solutions, and precision agriculture products, which align with Botswana’s broader economic diversification strategy ( IMF, 2023 ). However, this contribution still lags behind regional SEZs like South Africa and Mauritius, where SEZs contribute more than 15% to GDP ( UNCTAD, 2022 ).

The expansion of emerging technologies such as AI, the Internet of Things (IoT), blockchain, and satellite imaging has allowed Botswana’s SEZs to enhance productivity and increase their competitiveness on the global stage. For example, Gaborone’s Fairgrounds SEZ has benefited from the implementation of IoT-based quality control systems in the pharmaceutical sector, resulting in greater export potential to EU and AfCFTA markets ( Deloitte, 2023 ). Similarly, the integration of AI-powered predictive maintenance systems in manufacturing has reduced downtime and optimized production, making Botswana more competitive in precision engineering and pharmaceuticals.

The logistics sector has also experienced transformative growth, particularly through the use of blockchain technology to optimize trade efficiency. The Francistown SEZ’s pilot blockchain-based logistics system has streamlined cross-border transactions and reduced delays, thereby enhancing Botswana’s competitiveness in global trade ( World Economic Forum, 2023 ). Furthermore, the use of automated warehouse management solutions powered by AI has optimized inventory tracking and delivery timelines, boosting productivity and fostering investor confidence.

Agro-processing SEZs, particularly in Lobatse, have greatly benefited from the integration of satellite imaging and AI-driven climate analytics. These innovations have allowed for more precise crop yield predictions and sustainable water usage practices, resulting in a 30% increase in agricultural exports ( FAO, 2023 ). The use of drones for real-time crop monitoring and pest control has further improved the efficiency and sustainability of Botswana’s agricultural sector, positioning the country as a key player in sustainable agricultural exports within the region.

Despite the positive trends, Botswana’s SEZs face several challenges, particularly in terms of regulatory inefficiencies and infrastructure deficits. Bureaucratic delays in land allocation and inconsistent tax incentives have deterred potential investors from fully committing to these zones ( Zeng, 2016 ). Inconsistent regulatory frameworks and slow administrative procedures have resulted in project delays and capital flight to more investor-friendly regions such as South Africa and Rwanda. UNCTAD (2022) comparative study stresses the importance of streamlining administrative procedures, as seen in China and the UAE, where one-stop investment facilitation centers have significantly reduced bureaucratic red tape.

Additionally, inadequate infrastructure, including unreliable energy supply and limited digital connectivity, has hampered the development of high-tech industries within Botswana’s SEZs. Unlike their counterparts in China and Singapore, Botswana’s SEZs suffer from intermittent power shortages, which discourage industries that rely on uninterrupted energy supplies ( UNCTAD, 2022 ). This highlights the urgent need for Botswana to invest in renewable energy projects and digital infrastructure, such as 5G networks and cloud-based solutions, to remain competitive in the global market.

In response to these challenges, several policy interventions could help Botswana’s SEZs realize their full potential. The adoption of AI-enabled governance systems, which have proven effective in countries like Singapore and China, could streamline regulatory processes and reduce approval delays by up to 40% ( PwC, 2023 ). Additionally, investment in digital infrastructure, including 5G networks and cloud computing, is crucial for enhancing operational efficiency and attracting tech-driven FDI. Countries such as South Korea and Germany have leveraged 5G-powered industrial zones to drive economic growth and productivity ( ITU, 2023 ). Botswana can replicate this model by prioritizing digital infrastructure development within its SEZs.

Finally, integrating Botswana’s SEZs with regional digital hubs in Kenya, South Africa, and Rwanda could foster a seamless cross-border trade network, facilitating technology transfer and improving market access ( AfDB, 2023 ). This regional integration would enhance Botswana’s competitiveness and position the country as a key player in Africa’s emerging digital economy.

In conclusion, the findings from this systematic review highlight both the successes and challenges of Botswana’s SEZs. While these zones have contributed significantly to job creation, industrial growth, and GDP, regulatory inefficiencies and infrastructure deficits remain substantial barriers to their full potential. The integration of advanced technologies such as AI, blockchain, and IoT is essential for transforming Botswana’s SEZs into globally competitive hubs. Moreover, strategic policy interventions that focus on digital infrastructure, AI-enabled governance, and regional integration will be crucial for ensuring sustainable and inclusive growth in Botswana’s SEZs.

The systematic review of Botswana’s Special Economic Zones (SEZs) underscores their significant impact on investment inflows, employment generation, industrial output, and GDP contribution. While these zones have demonstrated potential in fostering economic diversification and attracting foreign direct investment (FDI), several challenges hinder their optimal performance. Addressing these obstacles through targeted policy interventions will be crucial for enhancing the competitiveness and long-term sustainability of SEZs in Botswana.

To attract and retain FDI in high-tech industries, Botswana must adopt a more strategic approach to investment facilitation. Several key policy measures can support this goal:

The shift toward automation and AI integration in SEZs has reshaped employment patterns. To mitigate job losses and maximize employment benefits, Botswana should implement the following strategies:

For Botswana’s SEZs to contribute more significantly to national GDP, key policy interventions should focus on industrial productivity and technological advancement:

Regulatory inefficiencies and infrastructure deficits remain significant barriers to SEZ growth. To address these challenges, Botswana should consider:

Enhancing Botswana’s SEZ competitiveness requires closer integration with regional and continental economic frameworks:

The analysis acknowledges that the reliance on older and incomplete datasets may limit the robustness of conclusions regarding the long-term impacts of Special Economic Zones (SEZs). This constraint is explicitly discussed as a limitation of the study, emphasizing the need for more recent empirical studies to validate and refine the findings. Future research should incorporate more recent longitudinal data to enhance the reliability of conclusions.

The study recognizes that excluding non-English literature may lead to gaps in capturing region-specific insights, particularly in non-Anglophone countries where SEZ performance may be influenced by unique policy frameworks and socio-economic factors ( Wang et al., 2019 ). This limitation is acknowledged in the study’s discussion, highlighting that linguistic constraints may reduce the comprehensiveness of the review. To mitigate this, future research should consider multilingual sources to ensure a more holistic understanding of SEZ dynamics across diverse contexts.

The methodology section has been expanded to provide a more detailed explanation of the criteria used for assessing the quality of included studies. Specifically, the study now outlines the inclusion and exclusion criteria, risk of bias assessment, and specific frameworks used to evaluate the methodological rigor of reviewed works ( Brown & Taylor, 2021 ). This addition strengthens the credibility of the findings and ensures transparency in the selection of studies.
