Research On Ecological Synergy Efficiency Of Industry Upgrading Of The Urban Agglomeration In The Middle Reaches Of Yangtze River

Industry is the focus of social and economic development.Under the new economic normal,promoting industrial upgrading and optimizing economic development layout play an important role in accelerating the process of urbanization and industrialization.With the development of industrial agglomeration and new urbanization,urban agglomeration has become the spatial development pattern of China.The urban agglomeration in the middle reaches of the Yangtze River is not only an important part of the Yangtze River Economic Belt,but also an important development area at the national level.Its development of industrial economic plays an important role in promoting the development of the Yangtze River Economic Belt,accelerating the overall rise of the central region,and improving the level of national economic development.Ecological priority and green development are the core requirements of the national strategy of the Yangtze River Economic Belt.Therefore,as well as accelerating the industrial upgrading of the middle reaches of the Yangtze River,attention should also be paid to coordinating the development of regional ecological and economy,promoting the quality and efficiency of economic development.It is important for achieving comprehensive,coordinated and sustainable development.This thesis firstly used the literature analysis method to sort out the existing literature from three aspects: industrial upgrading,ecological synergy and urban agglomeration in the middle reaches of the Yangtze River.Based on the knowledge of the subject and the theoretical research,this thesis proposed the research framework.Then the qualitative analysis method was used to analyze the industrial upgrading and ecological synergy status of this urban agglomerations.It is found that the secondary industry is still the main driving force of the economic development of this urban agglomeration.Based on the theoretical basis of natural ecosystems,this thesis proposed that the economic ecosystem of urban agglomerations is mainly composed of four subsystems.This thesis used the DEA model was to measure the ecological synergy efficiency of the urban agglomerations in the middle reaches of the Yangtze River.On the whole,the ecological synergy efficiency of this urban agglomerations is basically at a medium level in the country,and it tends to rise first and then decline.From the perspective of space,the ecological synergy efficiency of the three sub-cities is different.The ecological synergy efficiency of the Wuhan Urban Circle and the Changsha-Zhuzhou-Xiangtan city group show a trend of rising and then decreasing,while the ecological synergy efficiency of clusters around Poyang Lake shows a volatility trend of decreasing first,then rising and finally falling.
