Study On The Pattern And Regulation Of Economic Coordinated Development In Huaihai Economic Zone

Realizing the coordinated development of regional economy is a strategic choice facing China’s high-quality economic development at present and for a long time to come,and it is also a hot topic of economic geography.Taking the Huaihai Economic Zone as an empirical study,researching into the laws of temporal and spatial evolution of coordinated economic development in the inter-provincial border area,it is not only of guiding importance for decision-making on the coordinated economic development of the Huaihai Economic Zone,but also helps to enrich the connotation of high-quality economic development in the border regions between provinces.In terms of regional element coordination and spatial coordination,this study uses spatial analysis,system analysis and other methods to reveal the evolution traits of the temporal and spatial pattern of coordinated economic development in the Huaihai Economic Zone and reveal its influencing factors.The main contents include:(1)As for the time traits,the general,regional and interval differences in economic development in the Huaihai Economic Zone were all within from 2005 to 2018 The ups and downs have expanded;the volatility of the interval difference was relatively weaker than the former two,but the proportion was rising,the regional difference was dominant and the volatility was strong but the proportion was decreasing.Spatially,the economic spatial pattern of the Huaihai Economic Zone was characterized by a "three vertical and one horizontal" pattern along the main traffic arteries;the growth rate of county economic development showed an obvious "L"-shaped distribution in space.In 2018,in terms of spatial correlation,H-H counties had special "T" peculiarity;H-L counties were distributed in urban area of prefecture-level city near main railway lines;L-L counties were mainly located in the west and southeast of Huaihai Economic Zone;L-H-type counties were mostly clustered on the east side of the railway line in the middle of the region.(2)Research on the temporal and spatial features about the coordinated economic growth of Huaihai Economic Zone.From a factor synergy perspective,the use of the Haken model to identify the order parameters in pairs found that from 2005 to 2018,the regional factor endowment was always the order parameter that governed the coordinated economic development of the Huaihai Economic Zone.Improving the regional factor endowment was always the economic improvement of the Huaihai Economic Zone.The quality of development and the primary problem that must be solved to improve the level of economic synergy;although the fast variable has shifted from the industrial status in the first stage to the level of science and education in the second stage,the fast variable has always played a positive role.But,the effect of industrial condition in the first stage was stronger than that of the level of science and education in the second stage.Spatial dimension: as a whole,it was in the transition period from non-coordination to low-level coordination.From an inter-provincial perspective,the overall economic coordination of the Huaihai Economic Zone from 2006 to2018 was all highly volatile.Compared with 2006,the degree of coordination among cities has been smaller.Among them,the coordination degree of the cities in northern Jiangsu has always been in the high-value area,the cities in southern Shandong have mainly changed from a low coordination area to a high coordination area,Shangqiu has a moderately coordinated area transformed into a low-level coordination area,and Huaibei in northern Anhui has turned from a low value to a negative value,and its level of coordination was the worst.(3)Identify the drivers of coordinated economic development in the Huaihai Economic Zone.Over the same period,the absolute difference in the regression coefficients of the influencing factors between cities was small,and the general situation was the state of the infrastructure > openness to the outside world>government’s regulatory capacity;and the effects of the first two expanded,the latter dropped.Among these,the coefficient of regression of the infrastructure conditions played a promoting role and increased significantly,the opening to the outside played a restrictive role,and the government’s ability to regulate and control were played a promotional role,but the rating was weakened.In terms of spatial features,the regression coefficients for state infrastructure and government’s regulatory capacity both showed a significant decreasing in space from west,middle,and east.The limiting force of opening-up ability strengthened slowly from the order of eastern,central,and western towards a weaker southeast and a stronger northwest.
