Under the condition of information asymmetry in the market, the reputation, as a signal which reflects the information of enterprises, is delivered among different traders, and traders make choices depend on corporate reputation before making a deal. Establishing a good corporate reputation can not only make the enterprise get more development opportunities also can bring long-term economic value. W. Liu [1] studied the r & d outsourcing dynamic incentive mechanism based on the theory of the reputation, and established a dynamic incentive mechanism model of corporate r & d outsourcing; Y.Q. Tan [2] studied the effect of reputation in the outsourcing service provider reputation incentive mechanism, raised that reputation incentive can improve service provider’s effort in the early stage and constraint moral hazard from service provider; H.M. Guo [3] studied the dynamic incentive contract of supply chain which considered the cost of reputation, found out the relationship between reputation compensation and the type of manufacturers, cost, achieved the effect of weakening “ratchet effect”; B.H. Peng [4] built the trust game model between the module integrator and suppliers, pointed out that the reputation had became an effective incentive of cooperative members.

The service-oriented manufacturing network which is formed in the process of manufacturing and services integration development, is a kind of ability and demand cooperation network. The value module node of manufacturing enterprises base on service demand and service ability, service enterprises of relevant departments or personnel and customer is the composition of the SMN, and mainly contains service integration module node, service production and productive service module module node. Each node through the exchange of each others products or services to gain economic interests to promote the development of itself. The quality problem of the trade in tangible goods, and intangible items, such as service products, service attitude, goods delivery time. The above issues are collectively referred to as network node quality problems. H. P. Liang [5] presented the arrangement way of quality control in manufacturing network; J. X. You [6] studied the quality control of supply chain strategy problem under the condition of moral hazard; L. Q. Feng [7] marched the modular classification for SMN, established the model, respectively to measure the adaptability quality coordination and cooperation, the quality contract modular coordination level of quality.

This paper analyzes the role of the relationship between individual nodes from the perspective of the reputation contract, try to research the influence of reputation on the service module provider engaged in its own node quality behavior.

This paper considers only a simple SMN structure. For the convenience of modeling and analysis, the service production and the productive service module node are collectively referred to as service module provider, and the service integration module node is called service module integrator.

Hypothesis 1: Service module provider as the agent, service module integrator as the principal. Service module integrator cannot directly observe the management ability and the effort level what service module provider engaged in its node quality behaviors, can only observe some other variables.

Hypothesis 2: Principal-agent contract only has two phases, service module provider each phase of the output function:

is the output of service module provider in the first phase ; is service module providers management ability and its size is not related to the time; is the effort level that service module provider engaged in his own node quality behaviors in the phase, represents exogenous random factors, such as the uncertainty of technology or market.

Hypothesis 3: Effort level is the service module providers private information, output is the known information, ,; Assuming that the random variables are independent of each other, so, and is not relevant.

Hypothesis 4: Service module integrator is risk neutral, Service module provider is risk averse, is absolute risk aversion, is reputation discount rate, (risk averse risk neutral, risk appetite,).

Hypothesis 5: Service module provider’s effort cost function is, , is strictly increasing function, is the effort cost coefficient,.

Hypothesis 6: The principal-agent linear contract is, is service module providers fixed income what has nothing to do with the output of the current period, is the revenue share that service module provider Shares, called incentive coefficient,.

Hypothesis 7: The market is rational expectations. In the first phase equilibrium, is the actual level of effort that service module provider engaged in its own node quality behavior in the first phase. When service module integrator observed, he knows, but can’t separate and, in other words, he is not clear that except, is the results of the enterprise operation ability or the result of exogenous uncertainty. Service module integrator need on the basis of to infer.

Make, is the ratio of the variances of the and, [8].

According to the above hypotheses, it is concluded that the following formulas:

In the Formula (2), expresses the expectations that service module integrator to service module providers management ability, under the condition of determining the output in phase 1; in the Formula (4), expresses the expectations that service module integrator to service module providers output in phase 2 under the condition of determining output in phase 1; in the Formula (6), expresses the service module integrators certainty equivalent income; in the Formula (7), expresses the service module providers certainty equivalent income.

By contrasting Equations (22) and (10), , showing that after con-

sidering reputation mechanism, the effort level that service module provider engaged in his own node quality behavior in Phase 2 is better than the level without considering reputation mechanism. The quality of SMN is mainly depends on the effort level that service module provider engaged in his own node quality behavior, so we get proposition 1.

Proposition 1: After the introduction of reputation mechanism, the quality level of SMN in the phase 2 is improved.

By (28), get. When, , showing the optimal effort level that service module provider engaged in his own node quality behavior and the reputation incentive coefficient are positive relationship, we get proposition 2.

Proposition 2: when, the better reputation of service module provider, the higher optimal effort level that service module provider engaged in his node quality behavior, and the better quality of SMN.

By, when, , so we get proposition 3.

Proposition 3: Before the event, the more uncertain that service module integrator to service module providers management ability (), the greater reputation incentive effect. So it can effectively improve the effort level that service module provider engaged in his own node quality behavior, reduce the motivation that service module provider take the quality speculation. The quality of SMN can have a good control effect.

Comparing Formula (28) and (10), if, , so we get proposition 4.

Proposition 4: the effort level that service module provider engaged in his own node quality behavior in Phase 1 is better than the level without considering reputation mechanism, in other words, the quality level of SMN in the phase 1 is improved.

Analyzing formulas (25), we can see that reputation influences by influencing the fixed income. Formula shows that the income of service module provider in the second stage, on the one hand, is influenced by its current output, on the other hand also by service module integrator^’s expectation to its management ability. So we get proposition 5.

Proposition 5: when, reputation mechanism produces a positive effect which prompts service module provider to improve payment of the phase 1 in order to improve the production of phase 2.

Synthesize the above discussions, If reputation mechanism can well control the quality of SMN, it is thus clear that is a necessary condition.

In order to control the quality of SMN, improve the effort level that service module provider engaged in his own node quality behavior, this paper establishes an optimal dynamic linear contract model which combined explicit incentive mechanism and reputation incentive mechanism. The model under certain conditions can achieve the effective reputation incentive and enhance the reputation incentive effect. When meet the conditions, considering the reputation mechanism of the SMN node quality behavior model of the dynamic contract design compares to without considering quality reputation incentive mechanism of the SMN node behavior static model of the contract, effectively improves the effort level that service module provider engaged in his own node quality behavior, improves contract incentive strength, the quality of SMN and realizes the Pareto improvement.
