Study On The Spatiotemporal Differentiation And Influencing Factors Of Green Development Level In Huaihai Economic Zon

Since its reform and opening up,China’s economy has grown steadily and at a high rate,with growth and growth rates at a high level.Although China’s economy still demonstrates potential and resilience,its long-standing traditional development model has put pressure on resources and the environment.Against the backdrop of deteriorating resources and environment,and with the economic and social development model evolving with the times,China has gradually entered a new normal of slowing economic growth,optimising and upgrading its industrial structure,and seeking high-quality development,with green development becoming the most appropriate development path.The Twenty Tenth Report proposes that "Chinese modernisation is a modernisation in which man and nature live in harmony,where man and nature are a community of life,and where sustainable development is upheld to achieve the sustainable development of the Chinese nation".Green development is a comprehensive judgement of China’s economic development,and will run through China’s ambitious journey to build a rich and powerful modern nation.First of all,this thesis summarizes the relevant theories,concepts and connotations of green development,and the research progress at home and abroad.Secondly,from the aspects of economy,environment,policy and so on,the process and current situation of Huaihai Economic zone green development are analyzed.On this basis,by constructing the comprehensive evaluation index system of green development in Huaihai Economic Zone,the entropy weightTOPSIS model is used to measure the green development level of 20 prefecture-level cities in Huaihai Economic Zone from 2008 to 2018,and the spatial and temporal pattern is studied by using Their index,spatial autocorrelation,gravity model,social network analysis and other methods.Then,the influence factors of green development in Huaihai Economic Zone are studied by using obstacle degree model and geographic detector.Finally,combining the theoretical and empirical research results,the thesis puts forward the countermeasures and suggestions to promote the green development of Huaihai Economic Zone.The main conclusions:(1)The green development level of the Huaihai Economic Zone shows a fluctuating upward trend,but the increase is relatively small,with the three subsystems of green economy,social welfare and environmental protection showing an upward trend,and the scores of resource endowment and government mechanism showing a fluctuating downward trend;the green development level of the four regions of southern Shandong,northern Jiangsu,northern Anhui and eastern Henan all show a fluctuating upward trend,with southern Shandong and northern Anhui showing a decline followed by a rise The green development level in the four regions of southern Shandong,northern Jiangsu,northern Anhui and eastern Henan all showed fluctuating upward trends,with the southern Lu and northern Anhui regions showing a decline followed by a rise,while the northern Jiangsu and eastern Henan regions showed a stable growth trend.(2)The green development level of the Huaihai Economic Zone is relatively stable in terms of the Thayer Index,with the intra-regional differences showing a fluctuating downward trend and the inter-regional differences showing a fluctuating upward trend;the intraregional differences in North Jiangsu and East Henan show an upward trend,the intra-regional differences in North Anhui show a downward trend and the intra-regional differences in southern Shandong are relatively stable;the intra-regional differences in North Anhui and southern Shandong are significantly higher than those in North Jiangsu and East Henan..The overall green development coordination degree of the Huaihai Economic Zone shows a fluctuating upward trend,but the increase is relatively small,and the green development coordination degree of most cities is high.(3)The overall spatial pattern of green development level in the Huaihai Economic Zone is "high in the southeast and low in the west",with a gradual decrease from east to west;cities with relatively high green development levels exist in the north,northeast and south of the Huaihai Economic Zone,namely Tai’an,Rizhao and Bengbu;Xuzhou has become the center of green development in the Huaihai Economic Zone Xuzhou has become the center of green development in the Huaihai Economic Zone,but its radiation drive is insufficient.The spatial autocorrelation shows a pattern of "high-high" agglomeration in the southeastern coastal region and "low-low" agglomeration in the western region;the spatial linkage network forms a central polarised spatial pattern with Xuzhou as the core,spreading from the core to the periphery;the spatial distribution of the cohesive sub-group structure is highly consistent with the division of the four regions.The spatial distribution of the cohesive subgroup structure is highly correlated with the division of the four regions,and the crossprovincial links are relatively weak.(4)The main barriers to green development in the Huaihai Economic Zone include: the degree of industrial scale,financial support,the level of science and technology and education,and the market business environment;the barriers to economic development,urbanisation and the level of public services remain at a medium to high level,but show a clear downward trend;the barriers to resource utilisation efficiency,industrial structure,environmental protection,the level of science and technology and education,and the market business environment have increased significantly.The influence of traditional factors such as GDP per capita,urbanisation rate and investment in fixed assets per capita has always remained at a high level;the influence of investment in fixed assets per capita,construction land area per unit of GDP,carbon emissions per capita and the proportion of financial expenditure on science and technology has increased,while the influence of GDP per capita and urbanisation rate has decreased;in general,economic development and urbanisation are still the basic In general,economic development and urban construction are still the basic factors of green development in the Huaihai Economic Zone,but as the economy and urbanization gradually develop to a stable stage,the importance of factors such as environmental protection,pollution control,science and technology education level,industrial scale,industrial structure,resource utilization efficiency and financial support to green development gradually emerge.
