| The countryside is not only the main battlefield of poverty alleviation,but also the main position of ecological construction.Green development is the key to break the bottleneck of rural resources and environment,is the proper meaning of deepening the structural reform of agricultural supply side,and is an important grasp for accelerating the modernization of agriculture and rural areas.By changing the extensive production mode,practicing the green lifestyle and protecting and restoring the ecosystem,the rural green development is conducive to alleviating the constraints of natural resources in poor areas,reducing the environmental risks and health risks of the poor,creating opportunities for the poor to increase income and obtain employment,and then achieving sustainable poverty reduction.Rural green development is also of far-reaching significance for consolidating and expanding the achievements of poverty alleviation and realizing the smooth transition and organic connection from poverty alleviation to rural revitalization in the next stage.This study constructs an evaluation index system of rural green development based on three dimensions: industrial green development,residents’ green life and ecological protection and restoration,selects 29 provinces(autonomous regions or municipalities directly under the Central Government)in China as the research objects,and objectively evaluates the rural green development level of each province from 2010 to 2018 by entropy method.Based on the calculation results,this paper uses the Fixed Effect Model to test the poverty reduction effect of rural green development in China,and makes a concrete analysis on its regional heterogeneity and system heterogeneity.The results show that the level of rural green development in China has been on the rise in recent years,and has a significant poverty reduction effect.Rural green development has obvious characteristics of double thresholds in poverty reduction.When the level of rural green development is low,it does not have obvious poverty reduction effect.When the level of rural green development crosses the first threshold,the poverty reduction effect begins to appear gradually,and after crossing the second threshold,the poverty reduction effect further increases,showing an increasing trend of marginal effect on the whole.As far as different regions are concerned,due to the relatively high level of rural green development in the eastern region,while some provinces in the central and western regions have not yet reached the threshold value of significant poverty reduction effect,the poverty reduction effect of rural green development in the eastern region is significantly higher than that in the central and western regions.As far as the three subsystems of rural green development are concerned,industrial green development and residents’ green life have significant poverty reduction effects.However,due to the imperfect rural ecological compensation mechanism and low degree of ecological product value realization,rural ecological protection and restoration have not produced significant poverty reduction effects.Therefore,in order to further consolidate and expand the achievements of rural green development in poverty reduction,in the next stage,we should improve the level of rural green development in an all-round way,accumulate green power for the sustained development in areas which have been out of poverty,and reduce the poverty risk of poor marginal groups and the risk of returning to poverty for vulnerable households that have got rid of poverty.For these purposes,this paper puts forward four policy suggestions.Firstly,implement green production mode,promote agricultural transformation and upgrading to improve quality and efficiency.Secondly,construct a diversified investment pattern to make up for the shortcomings of rural residential environment governance.Thirdly,strengthen environmental supervision and law enforcement,protect and restore rural natural ecological space.Fourthly,improve the ecological compensation mechanism and innovate the way to realize the value of ecological products. |
