| Studies on Chamber of Commerce are of great important to China's private economic development and modern market system construction and improvement. However, because Chamber of Commerce is not purely a business form, neither the contract theory nor the collective choice theory takes Chamber of Commerce as their research object, and there is a lack of fundamental analytical framework in Chamber of Commerce economic research. This dissertation is to study Chamber of Commerce as common interest group providing club products from the perspective of the relation between enterprises and Chamber of Commerce through normative researches and empirical studies, using club theory, interest group theory, etc. This dissertation is to solve the following problems:What is the nature of Chamber of Commerce? What is the optimal size and border of Chamber of Commerce as a club? What is the impact of Enterprises' "voting with their feet" on the Chamber of Commerce? As an interest group, how does Chamber of Commerce form? Whose interests it represents? How do we measure the performance of the collective action? Background and object of this paper is mainly based on the Chamber of Commerce in Wenzhou, which is the representative of China's Chamber of Commerce.The author first conducts Economic Analysis on the club nature of Chamber of Commerce from the perspective of the internal organization of the Chamber of Commerce. Enterprise demand for the club products increases with the enterprise scale. Medium-sized enterprises have strongest demand and the highest degree of loyalty to the Chamber of Commerce. Chamber of Commerce membership affects their optimal scale, and the expansion of Chamber of Commerce scale will lead to congestion.The enterprises'entry, loyalty, appeal and exit show the significance of the Chamber of Commerce's performance increase. It costs little for enterprises to enter a chamber of commerce and the enterprises'loyalty to the Chamber of commerce is determined by the increased enterprises' utility with the increased performance of the chamber of commerce. When the quality of Chamber of Commerce declines, enterprises do not immediately withdraw from Chamber of Commerce, but rather appeal. Appeal mechanism is the main mechanism to avoid the recessions of organizational quality, while the existence of an alternative exit mechanism can also serve to prevent a recession of the organization.The nature of business interests is the economic nature of the chamber of commerce's collective action. The formation of chamber of commerce depends on the fact that expected return of collective action is greater than expected cost and affected by the industry boom and government intervention. This dissertation also discusses system arrangements for enterprises to maximize the utility in the chamber of commerce whose membership is heterogeneous. Minority of people unanimous agreement and price following are the main pattern of a "same voice" chamber commerce. Duopoly competition may occur and lead to non-efficiency of non-cooperative game.Performance of collective activity is the comparison of costs and benefits of Chamber of Commerce's operation, which is categorized into the organization's own quality and the effects of organizational activities. Finally, this dissertation also conducts an empirical analysis on the factors affecting organizational performance of Wenzhou Chamber of Commerce. The results show that there is significantly positive correlation between variables of the "president of the Chamber's work time", " participate rate of members to the General Assembly " and the Chamber of Commerce Organization performance. |
