【摘要】 选取2001-2019年的时间序列数据,采用DEA法对广东省物流业在不考虑环境资源约束条件下与考虑环境资源约束条件下的两种技术效率进行测算,并运用协整检验方法研究了环境规制因素与广东省物流业绿色技术效率之间的动态关系。结果表明:考虑非期望产出的绿色技术效率远低于不考虑非期望产出的传统技术效率,2001-2019年绿色技术效率处于递增趋势;环境规制因素两项指标与绿色技术效率存在协整关系,尤其是广东省物流业二氧化碳排放情况的改善对广东省物流业绿色技术效率的提升具有长期推动作用。更多还原

【Abstract】 Based on the time series data from 2001 to 2019,this paper adopts the DEA method to measure two kinds of technological efficiency of Guangdong’s logistics industry without considering environmental and resource constraints,and the co-integration test method to study the dynamic relationship between environmental regulation factors and green technology efficiency. The results show that the efficiency of green technology taking into consideration unexpected output is much lower than that of the traditional technology without such consideration. From 2001 to 2019,the green technology efficiency is on an increasing trend; there is a co-integration relationship between the two indicators of environmental regulation factors and the green technology efficiency,especially given that the improvement of carbon dioxide emissions of Guangdong’s logistics industry has a long-term role in promoting its green technology efficiency.更多还原
