This study employed a data envelopment analysis (DEA) by using slacks-based measure (SBM) with undesirable outputs to assess the industrial environmental efficiency of western China during the period of 2001-2015. The Malmquist index was further used to examine the changes in the industrial environmental efficiency of the analyzed region. The result showed that western China presented a low industrial environmental efficiency throughout the period of 2001-2015. Chongqing City was the only province that exhibited strong economic and environmental coordination. The level of technical development was identified as a key determinant of industrial environmental efficiency. This study provided policy implications on emissions reduction and the improvement of industrial efficiency. Limitations of the approach were provided to lay foundation for future studies.
本研究采用基于松弛的测度（SBM）的数据包络分析（DEA）方法，评估了 2001-2015 年期间中国西部地区的工业环境效率。进一步使用 Malmquist 指数来检验分析区域工业环境效率的变化。结果表明，2001-2015 年期间，中国西部地区的工业环境效率较低。重庆市是唯一一个表现出较强经济和环境协调能力的省份。技术发展水平被确定为工业环境效率的关键决定因素。本研究为减排和提高工业效率提供了政策建议。还提供了方法的局限性，为未来的研究奠定了基础。
