Research On The Impact Of Industrial Agglomeration On The Convergence Of China’s Green Economy

In recent years,while China’s economy is growing at a rapid pace,it is also facing the problems of environmental pollution and resource scarcity,and in 2020,the Chinese government proposed at the United Nations the goal of achieving carbon peak by 2030 and carbon neutrality by 2060.Promoting green economic growth is the fundamental guarantee to achieve China’s "double carbon" goal,and industrial agglomeration helps to achieve intensive use of resources through resource integration,which is an important way to promote regional green economic growth rate.However,while increasing the growth rate of green economy,the gap between the growth rate of regions is gradually widening,which will directly affect the realization of regional green economy synergistic development.Therefore,it is very important to study the influence of industrial agglomeration on China’s green economic growth and its convergence to narrow the regional gap and promote the coordinated and sustainable development of the region.Firstly,based on the review of new economic geography theory,economic growth convergence theory and sustainable development theory,this paper clarifies the mechanism of the effect of different modes of industrial agglomeration on green economy convergence;secondly,based on the panel data of 284 cities in China from2005 to 2019,we measure specialized agglomeration,irrelevant diversification agglomeration and related diversification agglomeration and green economy growth level respectively,analyze their spatio-temporal The results show that: the overall level of specialization agglomeration,unrelated diversification agglomeration and related diversification agglomeration and green economy growth are measured.The results show that: the overall level of specialization agglomeration is not high,but the overall trend is fluctuating and increasing,and the high agglomeration areas are mainly concentrated in Yangtze River Delta and Pearl River Delta.In terms of green economy convergence,there is σ convergence in the national and eastern regions,while there is no σ convergence in the central and western regions,while there is a convergence trend in China’s green economy growth,both in terms of absolute βconvergence and conditional β convergence.Finally,the effects of different patterns of industrial agglomeration on green economic convergence and spatial spillover effects are studied in depth through the spatial convergence model.To verify the reliability of the findings,the samples are tested in groups based on different city sizes and five major city clusters.The results show that after considering different modes of industrial agglomeration,the rate of green economy convergence in China increases,industrial agglomeration helps to narrow the green economy gap between cities,and the green economy growth rate of the region is driven by the growth rate of neighboring regions to a certain extent.From the decomposition of spatial effects,specialization agglomeration has a positive but limited effect on green economy convergence;unrelated diversification agglomeration helps accelerate the green economy growth rate in the region and neighboring regions,which in turn drives green economy convergence;related diversification agglomeration helps promote the green economy growth rate in the region,but inhibits the green economy growth rate in neighboring regions and suppresses green economy convergence in general.In view of this,based on the above findings and the actual situation in China,we propose relevant countermeasures to promote the convergence of China’s green economy based on industrial agglomeration.
