Research On Ascertaining Method Of Logistics Infrastructure Network Scale

Modern logistics, as an important part of social economics system and the most economical and reasonable integrated service mode, has been quickly developing in the whole world. It is the artery to drive country ecnomics development, and the base to support service industry. Its development level becomes one of the important signs to weigh the modern degree and the integrated national power. So, Modern logistics is called of "accelerator'.Along with setup and development of our market economics, related government branches and enterprises wake up to the accelerated function of modern logistics to economics. An upsurge of programming and constructing logisitics infrastructure network is rising in the whole country. It has been listed into the Outline of the 11th Five-year Plan for Country Economic and Social Development of People's Republic of China to enhance to integrate logistics infrastructure, construct big logistics hinge and develop regional logistics parks. It is awared that programming and constructing logistics infrastructure network in reason would effectively accelerate our country economics and modern logistics industry developing heathly.The chief issue of programming and constructing logistics infrastructure network is to confirm the rational scale of logistics infrastructure network, which would directly affect operation of logistics infrastructure network, and also work on modern logistics industry development. It has been paid more attention by experts and scholars inside and outside of the country, many of whom research on the problem. However, it is short of the research on the macroscpical level and economics development level. So confirmation the rational scale of logistics infrastructure network has been cried for, in order to cany out harmony development of modern logistics industry and economics.Therefore, the dissertation researches on Ascertaining Method of Logistics Infrastructure Network Scale. The main conclusions as following:1. Define logistics infrastructure network. On the basis of system theory and logistics network theory, the dissertation advances logistics infrastructure network is an aggregate of nodes and lines. Nodes and lines are the two basic factors, which are consisted of many sub-facors. They contact and restrict each other.2. Set up index systems. The dissertation designes systemically the economic index system of affecting logistics demand and the logistics index system of reflecting logistics infrastructure network scale, according to the relationship between economics and logistics demand, economics and logistics infrastructure network scale.3. Set up a Harmony Analyzing model Between Logistics Infrastructure Network Scale and Economy Development. According to system synthesis evaluation method and multi-system coordinating development evaluation method, the dissertation sets up the Harmony Analyzing model Between Logistics Infrastructure Network Scale and Economy Development.4. Set up logistics infrastructure network reasonable scale model. On the basis of main element analysis method, clustering analysis method and BP Neural Network analysis method, the dissertation advances coordinating codfficient calculation method of logistics infrastructure network scale and economics development. And the logistics infrastructure network reasonable scale model has also been set up.
