Research On Fixed Assets Investment System Of The Local Government Based On CAS

Since reform and opening, China’s fixed-asset investment has become the main driving force of economic growth. In recent years, the local governments in China have gradually become an important investment entities, the scale, structure, and whether the layout is reasonable of its fixed-asset investment directly affect the healthy and stable development of regional economy. Therefore, the study of local governments’ investment in fixed assets is of great strategic significance for local governments to develop appropriate fixed-asset investment policy and plan to improve the efficiency of it, as well as promoting the sustainable development of regional economy and the industry, to achieve its current and future economic and social development targets.Based on proving the fixed-asset investment system is a complex adaptive system with summarizing the research results of fixed-asset investment, the paper analyzes the influencing factors of fixed-asset investment, and builds investment system model of the local government in fixed assets based on CAS. Based on the work, moderate coefficient model of investment environment and security evaluation model of fixed-asset investment system are further established to evaluate the environmental factors’ adaptedness of the local government fixed-asset investment system under the constraint of the national or international standards and security stability of the system. Taking Beijing as an example, the paper predicts the scale of fixed-asset investment with the restrain of environment, resources, population using the time series models and neural network model through the Swarm platform, discusses the areas and fields of the fixed-asset investment in Beijing, simulates various environmental factors’ development and changes of fixed-asset investment system and evaluates Beijing fixed-asset investment system’s security stability. Finally, according to the investment situation and existing problems, the paper offers the suggestions to the development of Beijing fixed-asset investment.The research results show that, in the factors of fixed-asset investment system, water, population, land, energy environment (industrial waste, chemical oxygen demand), etc. is closely related to the scale of fixed-asset investment. Fixed-asset investment has achieved remarkable results in the control of industrial solid waste, industrial waste water, sulfur dioxide and chemical oxygen demand emissions, but it still need to be strengthened at the level of governance on industrial waste gas emissions;3eijing annual water saving and recycling rate is closely related to the fixed-asset investment, but it’s still insufficient to the facilities of water purification and wastewater treatment; the population of Beijing is closely connected with the fixed-asset investment, the investment on controlling population growth needs to be improved, and the population size has already exceeded the carrying capacity of land resources, so the investment and investment ratio around Beijing should be increased, to adjust the investment structure, optimize the layout, control the population growth and strengthen the dynamic monitoring from the macro regulation; in addition, it’s still far from perfect of Beijing fixed-asset investment in advancing transportation, ecological environment, improving people’s livelihood, resources&energy, industrial development and other key areas. Evaluation shows that security stability of Beijing local government’s fixed-asset investment system assets in a higher level, particularly in the investment environment and the associated body. Propulsion factor is relatively weak and needs more attention. Finally, the paper offers suggestions for the future fixed-asset investment and economic development policy from macroscopic perspective, as reference for the government departments to develop appropriate control policy.The local government fixed-asset investment system model basing on complex adaptive system reflects the complex relationship between the various elements in the internal system, has a great advantage than the past statistical method modeling, and its accuracy is much higher than the one-time modeling, and provides a scientific basis for the local government and Beijing government to develop appropriate regulatory policy of fixed-asset investment.
