摘要：

以中国七大区域的农业部门为研究对象, 引入水足迹–碳足迹–土地足迹为代表的环境足迹来表征其资源环境影响, 从溢出–反馈的新视角分析区域间的资源环境压力转移。首先在区域间投入产出模型的基础上分解出溢出–反馈效应模型, 并将其拓展至资源环境领域, 构建耦合环境足迹的溢出–反馈效应模型, 从区际双向影响的角度评价农业部门的资源环境压力转移。研究结果表明, 2007—2012年七大区域的农业部门区际水足迹–碳足迹–土地足迹的溢出–反馈效应空间差别较大; 反馈效应较为显著, 不应忽略。在各区域农业部门反馈占溢出的比例中, 华北区域最大, 均大于31.3%; 华东、华南和中南区域的比例也较大, 均大于10.7%。考虑到我国农业部门现有的区际资源可使用量和需求量与区域经济发展水平并不匹配, 应在一定程度上改善贸易结构, 建立区域一体化贸易模式。

Abstract:

This study takes seven regional agricultural sectors in China as the research object, and introduces water footprint (WF), carbon footprint (CF) and land footprint (LF) to analyze the spillover-feedback effect of these environmental footprints to characterize their resource and environment impacts. Based on the inter-regional input-output model, this paper first decomposed the spillover-feedback effects model, extended it to the environmental field, constructed the spillover-feedback effects model coupled with environmental footprints, and evaluated the transfer of resource and environment pressure in the agricultural sector from the perspective of interregional two-way impacts. The results show that the spillover effects and feedback effects of WF, CF and LF in seven regions of China’s agriculture sectors varied greatly in spatial level in 2007?2012. The feedback effects of WF, CF, and LF were more significant and should not be ignored. Through further analysis of the ratio of feedback effect to spillover effect of each region’s Agricultural Sector, it was found that the ratio of feedback effect to spillover effect of North (NO) region’s agricultural sector was the largest, all more than 31.3%. The ratio of feedback effect to spillover effect of East (EA), South (SO) and Central South (CS) regions’ Agricultural Sectors were also larger, all more than 10.7%. Finally, it was pointed out that the current interregional available resources in China’s Agriculture Sector did not match the demand and the level of regional economic development, so to some extent, the current trade structure should be improved to support agricultural sustainable development.

Key words:  environmental footprint, spillover-feedback effect, agricultural sector, China
