摘 要:采用生态足迹法测度我国各省区农村居民生活消费的环境压力,利用STIRPAT(Stochastic Impacts by Regression on Population,Affluence and Technology)模型分析农村人口和富裕对环境压力的具体作用,并在此基础上探讨农村技术环境效益.研究发现:我国各省区农村居民生活消费的生态足迹构成不尽相同,且具有显著的地域分异特征;人口数量是农村生态足迹变化的主要驱动因子,二者近同比例变化,富裕程度增加也将加剧农村环境压力;在现有观测数据范围内,分析结果不支持存在环境Kuznets曲线的观点;省际农村技术环境效益差异很大,多个省市存在较大的通过技术改善环境效益的空间.Environmental pressure of rural living consumption in every province of China was analyzed with ecological footprint as the environmental indicator.By using STIRPAT(Stochastic Impacts by Regression on Population,Affluence and Technology) model,specific effects of rural population and richness on environmental pressure were analyzed.Based on this,rural technical environmental benefits were discussed.The results showed that the constitution of ecological footprint from rural resident consumption in every province was different with significant characteristics of regional distribution.Population was the main driving factor of rural ecological footprint with the similar change ratio by these two indicators.Increase of richness also aggravated environmental pressure.Among the existing observational data,the results didn′t support the hypothesis of environmental Kuznets curve.Technical environmental benefits varied widely between provinces and there were more improving spaces for environmental benefits by means of technology in some provinces.
