摘要
生态效率是循环经济与可持续发展的有效测度。本文基于2008—2019年我国16个主产茶省的面板数据,运用非期望产出的超效率SBM模型测算我国茶产业生态效率并分析其时空变化特征及损失原因。结果表明,江北茶区生态效率较高,华南茶区与江南茶区次之,西南茶区较低,我国茶产业生态效率具有较大的提升空间;土地投入、劳动力投入与化肥投入冗余及总氮和总磷流失率过高是造成各主产茶省茶产业生态效率损失的主要原因。
Eco-efficiency is an effective measure of circular economy and sustainable development.Based on the inter-provincial panel data of 16 major tea-producing provinces in China from 2008-2019,this paper uses the Super-SBM-Undesirable model to measure the Eco-efficiency of China's tea industry and analyze its spatio-temporal variation characteristics and causes of loss.The results show that the Eco-efficiency of the tea industry in China is higher in Jiangbei tea area,followed by South China tea area and Jiangnan tea area,and lower in Southwest tea area.China's tea industry has more space for improvement.The reasons for the loss of Eco-efficiency of the tea industry in the main tea-producing provinces are the redundancy of land input,the redundancy of labor input,the redundancy of chemical fertilizer input,and the high loss rate of total nitrogen and total phosphorus.
