Research On The Infrastructure Investment Decision Of Village And Town Based On The System Coordinated Development

The infrastructure investment will promote the rapid development of new urbanization of the C hina, and the evaluation of their investment returns also receives more and mo re domestic scholars’ attention. The infrastructure investment of village and town has a significant impact on improving the level of village economy, increasing residents’ income and promoting the integration of urban and rural areas and so on. The research on the factors of the infrastructure investment decision will help develop a targeted investment strategy, but also provide a reference to the selection and decision- making process for the design of decision- making method, which has important theoretica l and practical significance.With the comprehensive use of the decision theory and method, the gray system theory, the theory of the coordinated development, the means of statistical software and MATLAB software and the methods of qualitative and quantita tive analysis, this paper carried out on the study on the infrastructure investment decision of village and town respectively from the macro and micro levels. Firstly, the "Infrastructure-Village" composite system was established according to the factors of infrastructure investment decision and related theories, then the relationship between infrastructure investment decision and the coordinated development of village and town was systematically analyzed, and the coordinated development mechanisms of the composite system was analyzed to provide the basis for decision- making. Secondly, the index system to evaluate the coordinated development degree of the composite system was built. The total infrastructure investment was behavioral variables, based on which the coordinated development model and differential analog model of the infrastructure investment was established for the coordinated development of the composite system. Thirdly, the index system to evaluate the facilities was built, and the weight of which was determined by means of entropy, then the TOPSIS method was used to sort the alternatives. Finally, it took the Sij iazi town as an example to demonstrate the models of macro and micro infrastructure investment decision- making, the empirical analysis gave the corresponding recommendations of the investment decisions.It could be found in the infrastructure investment’s dynamic model of coordinated development of Sijiazi town that among all the related factors, the level of the production infrastructure, the traffic infrastructure, the environment infrastructure, the medical and care infrastructure,the culture and technology infrastructure, economy and efficiency, social security, loss of resources and development and environmental damage have a great er role in promoting the amount of the infrastructure investment, however, the economic structure has a strong inhibitory impact on the infrastructure investment, others have different degrees of impact. In addition, the increase of the total infrastructur e investment has a certain degree of influence on the coordinated development of the IESRE composite system. Therefore, the relevant government departments could determine the total amount of investment and infrastructure investment and the direction of the investment based on the analysis above related factors. It was based on the interpretation of the parameters of the village infrastructure investment model that water facilit ies were chosen as the empirical analysis of microscopic infrastructure investment decision model. The score of single- village water supply facilities ranked first among the three alternatives by the comparation of the comprehensive evaluation score. Finally, this paper presented a corresponding recommendations of the investment decisions.
