| After more than four decades of reform and opening up,socialism with Chinese characteristics has blazed a new path that has attracted worldwide attention.The Fifth Plenary Session of the 19 th CPC Central Committee put forward the concept of "adhering to clear waters and green mountains are gold and silver mountains" and made clear the long-term goal of "better life for the people,common prosperity for all the people and more obvious substantive progress".It can be seen that green development has become an important path to achieve common prosperity in urban and rural areas in the new historical period.Rural areas have also welcomed unprecedented opportunities and challenges because of their abundant green resources.After comprehensive poverty alleviation in 2020,how to consolidate and expand the crucial poverty results,and its effective connection with rural revitalization,how to improve the overall coordination mechanism of ecological civilization and economic development,depending on the economic and social comprehensive green transformation,the construction of common prosperity of the new urban and rural relationship of workers and peasants,to speed up the agriculture modernization,ultimately achieve common prosperity for the urban and rural areas,has become an important topic.After systematically reviewing and reviewing the domestic and foreign research literature on urban-rural income gap and green development,Based on the theory of new division of labor economics,this paper questions the one-sided assertions of neoclassical economics that "reducing carbon emissions will slow down economic development,there is a dilemma between environmental protection and economic development" and that "the continuous increase in returns to scale mainly comes from external technological progress".This paper refines some important thoughts of labor division economics,and demonstrates the organic unity of the four aspects of new labor division economics and the connotation of green development in the new era.That is,the specialization of labor,the diversification of professions,the detour of production and the organization of the economy.They have respectively brought about specialized production with reduced quantity and improved quality,differentiation and specialization of green products,innovation of green technologies and prosperity of intermediate products,and at the same time encouraged economic entities to join the larger market.Green is circulation evolution into a chain to division of labor,the paper constructs the dynamic green common prosperity theory framework,creatively put forward the "green common prosperity thoughts" xi new era concept,this new theory reveals the thought embodies the rich wisdom of Chinese traditional philosophy,with the economic characteristics of socialism with Chinese characteristics,is the latest achievements of sinicization of marxism,and laid a foundation for later research theory.In this paper,a mathematical model including environmental system,economic system and the corresponding transaction costs is established,and the ultra marginal comparative static analysis of green development is carried out.At the same time,it is proved that the key to the harmonious development of economy and environment is to solve the dilemma conflict between transaction cost and transaction efficiency,and the key to solve the dilemma conflict is to find the optimal corner solution,that is,the optimal combination decision structure under the dynamic green evolution of labor division.Green evolution with deepening division of labor can generate green technology,give play to comprehensive comparative advantages and improve transaction efficiency,thus expanding the transaction network,while the detour production in the expanded transaction chain will further enrich the variety of green products and stimulate the potential of green investment.The inner mechanism of the green development in urban and rural areas to promote common rich is that along with the evolution of the division of the green,the structure of division of labor develops from the state of self-sufficiency which never exceeds the level of food and clothing to partial division of labor and then to complete division of labor,completely to the balance of the looming economic equilibrium,everyone has the equal market power and opportunities to share green resources and achievement of justice,everyone can become the new producers and monopoly,so as to realize the pareto improvement.At this point,monopoly,innovation and common prosperity coexist.Therefore,only the green evolution with deepening division of labor can realize the dual optimization of urban and rural production efficiency and social welfare.There is a complex nonlinear relationship between green development and urban and rural common prosperity.Therefore,in this paper,through the calculation in the provinces of10 years green total factor productivity as explained variable,in urban and rural income ratio is as explained variable based panel threshold model building,discovered in the process of reform and opening up,our country technical trade efficiency and system efficiency good trend of increased year by year,most of the provinces,such as Yangtze river delta region,the eastern coastal areas in high efficiency range,the central and western regions is gradually entering the high efficiency.At present,there are still relatively backward Xinjiang,Ningxia,Qinghai,Gansu and other provinces and cities.On the basis of this model,the robustness of the regression results is tested with the green development index of the provinces and cities along the Yangtze River Economic Belt in 10 years.It is further verified that the dual green positive cycle evolution of division of labor on the demand side and supply side can promote the common prosperity of urban and rural areas and realize the leap-forward development of economy.Moreover,the promotion effect is more significant in the higher threshold range of trading efficiency.According to the internal mechanism verified by empirical analysis,this paper designs the corresponding mechanism in four parts: the greening of the supply side,the greening of the demand side,the support matching of big data,the fair and just market and the distribution system.Finally,based on these findings,the paper puts forward policy suggestions and institutional arrangements to promote the green development of urban and rural common prosperity from three aspects: improving the efficiency of technology trading leaded by deepening the green evolution of labor division;improving institutional trading efficiency guaranteed by promoting green institutional reform;establishing green socialist values by advocating public participation as the goal.In conclusion,The content of this study is not only to abandon the past black development paradigm of sacrificing the ecological environment for economic benefits,but also to advocate the ideological transformation of the traditional idea that the countryside is backward,fully attach importance to the rural value,and emphasize the important position of the countryside in the division of labor between urban and rural areas.This paper from the supply side to deepen the green evolution of labor division,from the demand side to cultivate people’s green consumption concept and values,change the past extravagant consumerism and materialism,reshaping the structure of urban and rural labor division,transform the rural abundant green resources through green technology into green capital.In addition,the progress of social civilization must consider the vulnerable groups in order to be called "good governance".Therefore,this paper studies the path of green development and the results of green development,based on the construction of a socialist economic theory system with Chinese characteristics featuring green,healthy and beautiful features,such as technological innovation,knowledge sharing,solidarity and mutual assistance,simplicity and moderation,and profound culture.The ultimate goal is to achieve green and sustainable development in urban and rural areas,and to build a socialist society in which each performs his or her own duties,does his or her best,and is prosperous for all,which is of great theoretical value and practical significance. |
