Research On Spatio-Temporal Variation In Regional Economic Growth

The unbalanced development of regional economy is a general economic and socialphenomenon, the heterogeneity of regional economy development has existed and occurred.Along with the economic globalization, regional economic integration arrival,, the form，characteristic, competition ability and research methods of regional development have producednew change, and endowed with new connotation. Yangtze River Delta metropolitan region istaking Shanghai as the leader of the Jiangsu, Zhejiang Economic Zone, currently the fastestgrowing economy, the largest total economic output, the most development potential of theeconomy plate. Therefore, Yangtze River Delta metropolitan region economy developmentstudies are better to provide reference for the realization of regional economic integration.Based on the above the level of administrative units for basic research unit, finished thecollection of Yangzhou, Taizhou, Shanghai, Nantong, Nanjing, Zhenjiang, Changzhou, Wuxi,Suzhou, Huzhou, Jiaxing, Hangzhou, Shaoxing, Ningbo, Zhoushan, Taizhou16city1993-2009national economy development data. Analysising of the rate of economic growth, the scale ofeconomic growth, economic structure, labor efficiency on the Yangtze River Delta metropolitanregion economic growth characteristic, discovered the economic growth in Shanghai andHangzhou to the nodes of the" Z" font space structure to" K" font change in Yangtze RiverDelta metropolitan region. Through the base the Buddhist nun coefficient, Theil index andgeneralized entropy calculation of Yangtze Delta metropolitan area economic growth difference,quoting Wolf Sen index and urge-King of regional economic polarization index calculation,found in Yangtze River Delta metropolitan area economic growth difference experienced firstdecreases, then increases, and then decreases in three stage, economic polarized growthexperienced first abate, after strengthening, and then weakened in three stages. Studies regionaldifferences in the effects degree of economic growth in the Yangtze River Delta,from naturalresources, investment, trade, transportation, information, labor, financial and other aspects, found industry structure, investment, trade that is the most important factor of regionaleconomic growth. With GDP of average per capita index, with the municipal administrativearea as the basic unit, using multiple linear regression method, on2015,2020in Yangtze Deltametropolitan economic polarized growth, temporal and spatial variation characteristics weresimulated, found that Su Xichang axis and Hangzhou-Ningbo axis the strength of rapideconomic increased, and other areas by Su Xichang axis and Hangzhou-Ningbo axis to theperiphery of the decreasing trend is more clear. Through main problem analysis of the influenceof Yangtze River Delta metropolitan region competition ability, put forward to promote theYangtze River Delta metropolitan region competitive power needs from four coordinate in theregional economic development and the total area of the subscale structure, regional industrialstructure, regional economic structure, regional development timing.
