摘要
推进农业绿色发展是乡村振兴战略的关键点。深入探讨农业经济与农村环境质量之间的关系对于重塑常规农业向绿色可持续方向转变具有重要意义。本文基于我国31个省区农村环境质量综合评价指数,建立了农业经济发展水平与农村环境之间的计量模型,对二者关系进行了环境库兹涅茨曲线(EKC)验证。研究结果表明:(1)农村环境质量与经济发展水平呈倒"U"型曲线关系,符合EKC假说,这表明随着经济水平增长,农村环境质量将呈现先恶化后好转变化态势。但EKC曲线并不意味着污染可以自然而然得到解决,深层原因分析显示只有技术进步及政府对环境问题实施治理,农村环境和经济发展才可实现"双赢"。(2)农村环境质量好转转折点为人均GDP 57393元/人(2000年不变价),目前上海、天津、江苏3省(市)达到了这一门槛,大部分省份离转折点有一定距离。(3)不同发展水平省份EKC假说所处阶段存在区域差异。东部省份已呈现倒"U"型曲线,中部和西南地区多数省份接近转折点,西北省份仍处于倒"U"型曲线左侧。
Green development of agriculture is a key point in the rural revitalization strategy.An in-depth discussion of the relationship between rural economy and environmental quality is crucial for the transformation of traditional agriculture into a green and sustainable agriculture.Based on the comprehensive evaluation index of rural environmental quality of 31 provinces,this article establishes an econometric model,and verifies the Environmental Kuznets Curve(EKC)Hypothesis between rural economic development and environmental quality.The results shows that:(1)There is an inverse U-shaped Kuznets Curve between rural economic development and environmental quality.It indicates that rural environmental quality will be deteriorated and then be improved with economic growth.However,it doesn’t mean that pollution can be solved naturally.Only technological progress and government’s treatment of environmental problems can achieve a win-win effect in both rural economic development and environment.(2)The inflection point of the improvement of rural environmental quality is at the per capita GDP of 57,393 yuan/person at 2000 constant prices.Shanghai,Tianjin and Jiangsu have reached this threshold,but most provinces are still lag behind.(3)Regional differences exist in different stages of EKC hypothesis at different provinces.The eastern region shows an inverted"U"curve,most of the central and southwestern region are close to the inflection point,but the northwestern region are still on the left side of the inverted"U"curve.
