Research On Regional Financial Ecology Based On Complex Adaptive System Theory

Finance is the driving source of economy. It is significantly meaning for a economic body to keep the financial system harmonious orderly operating for the sake of its continuity, normal and stable development. Regional financial ecology system is a combination of the interactive relationship between the regional finance and the environment which it belongs to. As a Complex Adaptive System(CAS), this system features such characteristics as complex structure, nonlinear effect, self-regulation function, and so on. So the research aiming at the system should be brought into the framework of CAS theory.The paper conducts research process as follows. Firstly, adopting CAS theory and system dynamics tool, it establishes a model to analyze the functional structure characteristics and balanced mechanism of financial ecology system, and comes to the following conclusions. First of all, the functional parts of regional financial ecology system contain resource sub-system, implementing sub-system and environment sub-system, which jointly compose the category of regional financial ecology system and realize its function though coordination and organic combination. In addition, regional financial ecology balance is composed of main-body balance, market balance and environment coordination. Main-body balance refers to improving the profitability of regional financial ecology main-body and relative stability of the system structure. Market balance covers the behavioral optimization and quantity balance of regional financial ecology main-body during certain time span. Environment coordination is formed by the two balances above, explaining the dynamic stability of regional financial ecology system structure.Secondly, based on the theory analyze above and relative data, the paper empirically examines the balance of regional financial ecology system in Shandong province. The results suggest the characteristics of regional financial ecology balance of this province. First, regarding to the overall quantity, the system balance level of samples is comparatively high. Second, as to the layers of system, there exist structural differences among samples on the regional financial ecology system balance, and the margin is large between the highest and the lowest. Third, considering the relation with economy development, There is no evidence illustrating significant relationship between regional financial ecology balance and regional economy development.Finally, according to above theory analyze and empirical results and standing on the present situation of regional financial ecology construction in Shandong province and the whole nation, the paper puts forwards to policy choice to optimize regional financial ecology. It is necessary to perfect financial legislation, innovate modern financial ecology main-body, establish harmonious relationship of double identities of local government, and construct financial supervision system based on and directed in self-regulation ability of financial ecology, in order to promote the coordination of finance and economy and the balanced development of financial ecology sub-system.The policy implications of the paper is that regional financial ecology construction is a complex engineering and its development needs the application of system method and theory, it ensures harmony relationship between the system and environment. The innovations of this paper is that we make an innovative reconstruction on the functional structure characteristics and balanced mechanism of financial ecology system depending on CAS theory and Eco-development.
