The Input Optimization Of Capital To Port-Related Industries And Effects Analysis In Construction Of Shipping Center

The port-related industries achieve more inputs when the shipping center are built, and the development of the port-related industries will conduct to the others by the relationship of supply-demand and result in the development of regional economies. The input-output(I-O) table describes the supply-demand relationship among the industries in the economic system and can be used to analyse the interaction among the industries. This paper analyse mainly the input optimization of capital and effects in construction of Dalian international shipping center with the I-0 methods.Firstly, based on the I-0 table in Liaoning, the paper applies multi-objects fuzzy clustering to build the new I-0 table with two parts:the port-related industries and the port-unrelated industries. Then with linear palnning mothed, the input distributive modes are optimized and the output effects are researched. Secondly, the paper evaluates the emission of the pollutant and the consumption of the energy of the industries with fuzzy rough sets, and built the double-layers planning model to study the input modes to industries and the output effects considering the environmental factors. Third, the dynamic inverse matrix is calculated and the dynamic I-0 relations among the industries during the five years are researched. At last the paper employs the dynamic palnning mode to analyse the input distribution to industries and the output effects.The results show that the amount imbalance and the time imbalance consist in the input to industries and the ouput from industries. To the construction of Dalian international shipping center, the relation of industries must be considerd. Through the optimal distribution of the input to industries and the optimal plan of the orders of industrial development, the linkage rule of the outer input and the interaction among the industries can be combined effectively, the object of shipping center and the balanced development in the industries woud be realized at the same time. Otherwise, the research indicate that during the construction of Dalian shipping center, the influence to environment can be alleviated through the rational distribution of the input among the industries...
