Study On The Impact Of Financial Environmental Protection Expenditure On Ecological Efficiency In Inner Mongolia

The 14 th Five-Year Plan period is a critical period for the construction of ecological civilization in China,and it is necessary to build a better ecological environment to meet the growing needs of the people.Improving ecological efficiency is one of the important measures of ecological civilization construction.Fiscal environmental protection expenditure is an effective means to protect the environment,control pollution and improve ecological efficiency.In 2007,the government’s revenue and expenditure reform included spending on environmental protection in its budget,and the scale of government spending on environmental protection increased year by year.This also shows the determination and confidence of the whole Party and the whole country in winning the battle against ecological civilization.Inner Mongolia is the main ecological barrier in the north of China,and its ecological civilization construction is of great significance to the sustainable development of China’s economy and society.Therefore,it is of great practical significance to discuss the impact of financial environmental protection expenditure on ecological efficiency in Inner Mongolia.Based on the public goods theory,externality theory,sustainable development theory,as well as the understanding of the current situation of financial expenditure on environmental protection in Inner Mongolia.The ecological efficiency of 12 cities in Inner Mongolia from 2010 to 2019 was taken as the research object,the ecological footprint method was used to measure ecological efficiency,and the Kernel density was estimated.The study found,at the macro level,from 2010 to2019,eco-efficiency showed fluctuating and increasing trend in Inner Mongolia.At the micro level,During the study period,there were obvious regional differences in the ecological efficiency of Inner Mongolia cities,However,the regional ecological efficiency gap is gradually narrowing,and there is dynamic convergence.In ecological efficiency measure,STIRPAT model is used to empirically test the impact of fiscal environmental expenditure on ecological efficiency.The results show that: although fiscal environmental protection expenditure has a significant positive impact on the improvement of ecological efficiency,its impact on ecological efficiency is inverted U-shaped,and ecological efficiency does not always increase with the increase of fiscal environmental protection expenditure scale.Other control variables have some promoting or inhibiting effects on regional ecological efficiency.In view of the economic inertia of ecological efficiency,the delay in ecological efficiency is introduced as the explanatory variable,In order to solve the endogenous problem of ecological efficiency,the study found that the ecological efficiency is a continuous accumulation process,and the ecological efficiency of the last phase is obvious,so it is important to protect the present ecological environment.Finally,the optimization countermeasure of financial environmental protection expenditure is proposed,in order to provide a reference for the improvement of ecological efficiency in Inner Mongolia.
