| The tourism industry has developed rapidly worldwide with its advantages of high economic benefits and strong driving effects,and has received attention from multiple governments.The tourism industry has both direct and indirect multiplier effects on the modern world economic system.After the reform and opening up,China’s tourism industry has not only become an important pillar of the national economy,but also a driving force for improving people’s happiness index.In recent years,with the strong support of some policies and systems,China’s tourism industry has developed rapidly and has become a pillar industry of the national economy.However,with the rapid growth of China’s tourism industry scale,there are also prominent issues such as consumption and waste of tourism resources,and damage to the natural environment.As an important means of measuring the sustainable development level of tourism,the precise measurement and comprehensive evaluation of tourism ecological efficiency are of great value for understanding China’s tourism ecological level.Therefore,actively promoting the development of green economy and emphasizing the construction of ecological civilization is the correct path to achieve sustainable development.This article takes Henan Province as empirical targets from a two-dimensional perspective of geographical time and space.In terms of time evolution,the Super SBM model based on non-expected output is used to calculate the tourism ecological efficiency of Henan Province from 2010 to 2020.Through overall and city analysis,the evolution trend of the ecological efficiency of 18 cities is divided into growth type,fluctuation type,and stable type to explore the dynamic characteristics of the evolution of tourism ecological efficiency over time.In terms of spatial deduction,standard deviation ellipse and center of gravity trajectory model are used to outline the spatial evolution path of tourism eco-efficiency.The entropy method was used to calculate the efficiency of tourism economic development level.Finally,the relationship between tourism ecological efficiency and tourism economic development was proved by ADF test and Granger causality test,and the dynamic correlation between the two variables in the study period was explored by the vector autoregressive model :(1)The tourism eco-efficiency in Henan Province experienced a change from low efficiency to high efficiency,but with the passage of time,the response to itself gradually weakened;(2)The development of tourism industry in Henan Province shows the trend of spatial agglomeration.Zhengzhou,as the development center,plays an important role in the development of tourism.However,the gap between cities is still large,so it is necessary to further strengthen the development of tourism industry and improve the development level of tourism economy.(3)The improvement of tourism ecological efficiency in Henan Province needs the support of tourism economic development,but the development of tourism economy also needs the guarantee of ecological efficiency.It is necessary to pay attention to the coordination between ecological protection and economic development,establish a sustainable tourism industry chain,and promote the healthy development of tourism.In response to the above conclusions,this article provides suggestions for strengthening regional cooperation,protecting and repairing important ecosystems,optimizing and upgrading regulatory systems,using environmentally friendly building materials for public facilities,improving the image of scenic spots,strengthening information infrastructure construction,enhancing public service functions,and improving emergency systems between cities from the perspectives of tourism industry ecological environment and tourism economic development,Starting from promoting the two-way synergy between tourism economic development and tourism ecological protection in Henan Province,providing policy inspiration and scientific reference for the sustainable development of tourism in Henan Province. |
