| Based on the characteristics of economic development under the new situation,grasping the contradictions and cruxes that affect the improvement of land efficiency is the key to preventing and resolving risks and challenges,and promoting the development of stable and long-term development.Green technological innovation has become the key to improving the ecological efficiency of land use.Land use has entered a period of transition from a speed type to a quality type,and the ecological benefits of land use have received further attention in the process of land use.Therefore,green technology innovation has become an urgent need for the high-quality development of the regional economy and the "14th Five-Year Plan" period.At the same time,the development of the Zhengzhou metropolitan area is accompanied by potential,opportunities and challenges.The upgrade and expansion of the metropolitan area also put forward higher requirements for the ecological benefits of land use.How to adjust the ecological use of land is an urgent problem to be solved.The study of green technological innovation as a driving force to promote the improvement of the ecological benefits of land use in the Zhengzhou metropolitan area not only responds to the call of the state at the policy level,but also provides important reference for the coordination of urban economic development and ecological environmental protection in Henan Province.The expected goal of improving the ecological benefits of land use in the Zhengzhou metropolitan area.Based on the theoretical research on green technology innovation and land use ecological benefits at home and abroad,this paper further deepens the research on green technology innovation and land use ecological benefits,and seeks the role and connection between the two.The evaluation index system of land use ecological benefit of Zhengzhou metropolitan area is established on the basis of the constituent elements of ecological benefits of land use.Based on the data of the metropolitan area from 2011 to 2020,SPSS21.0 is used to perform principal component analysis on the data to obtain the land use ecology of Zhengzhou metropolitan area.The comprehensive level of benefits is evaluated,and the comprehensive scores obtained are used to explain the development trend of the ecological benefits of land use in the Zhengzhou metropolitan area from 2011 to 2020.Calculate and compare the comprehensive scores of the ChangZhu-Tan metropolitan area,which is also the central region,analyze the gaps and shortcomings of the Zhengzhou metropolitan area in 2020,and explore the current problems and predicaments in the land ecological use of the Zhengzhou metropolitan area.Theoretical analysis of the mechanism of green technological innovation promoting the ecological benefits of land use,and exploring the internal synergy and direct promotion of green technological innovation.Conduct empirical analysis,choose the comprehensive score of land use ecological benefits as the dependent variable,and the related variables of green technology innovation as independent variables,establish an OLS regression model to analyze the effect of green technology innovation on the improvement of land use ecological benefits.Finally,clarify the optimization path of green technological innovation to the ecological benefits of land use in the Zhengzhou metropolitan area,explore solutions,and promote sustainable development.The main research conclusions of this paper include:(1)The comprehensive score of the ecological benefits of land use in the Zhengzhou metropolitan area has been increased from-0.4131 in 2011 to 2.8553 in 2020.Although there has been a downward trend in some years,the overall land use in the Zhengzhou metropolitan area has increased in recent years.Use ecological benefits to develop for the better.(2)Through the benefit score comparison between Zhengzhou Metropolitan Area and the neighboring Chang-Zhu-Tan Metropolitan Area,there are problems such as urgent improvement of ecological conditions,tight resource conditions,severe emission control,and insufficient ecological coordination protection.(3)Green technology innovation performance,green technology knowledge creation,green technology innovation subject,green technology innovation environment,and green technology innovation transformation are the five aspects to measure the ecological benefits of land use in the Zhengzhou metropolitan area.However,after regression analysis and verification,only green technology Innovation performance,green technology knowledge creation,the main body of green technology innovation,and the environment of green technology innovation have a role in enhancing the ecological benefits of land use,among which green technology innovation performance plays the most important role.However,the transformation of green technology innovation has not significantly improved the ecological benefits of land use.(5)To further improve the ecological benefits of land use in the Zhengzhou metropolitan area,it is necessary to implement regional green technology innovation.Green technology knowledge creation is the technical support for green technology development,and can be used as an initial path to improve the ecological benefits of land use;the main body of green technology innovation is a key link in the development of green technology innovation,and can be used as a development path to improve the ecological benefits of land use;green technology innovation performance is The output results of green technology innovation can be used as a mature path to improve the ecological benefits of land use;the green technology innovation environment has a limited role in improving the process of green technology innovation,and can be used as a supplementary path to improve the ecological benefits of land use.From the above four aspects,solve the main dilemma facing the current metropolitan area and seek a breakthrough. |
