Research On The Spatial Structure Evolution Of The Leading Industry Of Yangtze River Delta

Yangtze River delta has achieved remarkable achievements in areas such aseconomic and industrial development since the reform and opening. With the rapiddevelopment of global economy integration and the international division of labor,China has become with labor advantage, Yangtze River delta with its absolutesuperiority of manufacturing has become the important areas to promote the growth ofthe national economy. However, as our country is gradually losing its labor advantage,the energy is increasingly scarce and environmental protection in recent years, theYangtze River delta is losing its manufacturing advantage. Whether the spatialstructure of the leading industry of the Yangtze River delta region is reasonable, whatis the future of the spatial structure of its leading industry, how to ensure continuedsolid growth in Yangtze River delta is the focus of common concern from all walks oflife today.This article studies the spatial structure evolution of the leading industry ofYangtze River delta and influence factors by using leading industry theory combinedwith the industrial spatial structure theory and using gravity center method. First, useprincipal component analysis (PCA) to identify the leading industry of the YangtzeRiver delta, choose three representative industries, namely the black metal smeltingand rolling processing industry, general equipment manufacturing and computer andcommunication equipment manufacturing industry as the research object and analysisthe present development situation of the three representative industries.Then determine the parameters used to measure the spatial structure evolutio n ofthe leading industry–the industrial gravity center, the industrial gravity center movingdistance, the uniformity index and regional weight to describe the spatial structureevolution track of the above three industries, then get the spatial structure evolutiontrack of the leading industry of Yangtze River delta that industrial gravity center shiftdirection is from southeast to northwest, also from Zhejiang province to Jiangsuprovince with black metal smelting and rolling processing industry, gener alequipment manufacturing and computer and communication equipmentmanufacturing industry as a representative. And analyze the spatial structureevolution characteristics of the leading industry of Yangtze River delta to get thespatial structure evolution characteristics of the leading industry of Yangtze Riverdelta.Finally, put forward theory assumes that the factors affecting the spatial structureevolution of leading industry of Yangtze River delta, establish econometric model,analyze the influence factors of the spatial structure evolution of the Yangtze riverdelta leading industries from four aspects as the natural advantages, agglomeration economy and industrial structure and market demand. It is concluded that the blackmetal smelting and rolling processing industry, general equipment manufacturing andcomputer and communication equipment manufacturing industry have its owninfluence factors and the influence of size in each city of Yangtze River delta.
