黄河流域和长江经济带制造业绿色转型效率对比

以黄河流域和长江经济带沿线19个省份为样本,建立超效率SBM模型测算分析了2013—2022年黄河流域和长江经济带的制造业绿色转型效率,并利用“泰尔指数”进行转型效率的差异性分析。研究发现,长江经济带绿色转型效率呈上升趋势,相反黄河流域发展相对缓慢;通过差异性分析发现黄河流域的域制造业绿色转型效率低于长江经济带,并且黄河流域中各省份的差异性相差较大。

Comparative Study on the Efficiency of Green Transformation of Manufacturing Industries in the Yellow River Basin and Yangtze River Economic Belt

Taking 19 provinces along the Yellow River Basin and the Yangtze River Economic Belt as samples, a super-efficient SBM model was established to measure and analyze the green transformation efficiency of the manufacturing industries in the Yellow River Basin and the Yangtze River Economic Belt from 2013 to 2022, and a differentiation analysis of the transformation efficiency was conducted by using the "Tyrell Index". It is found that the green transition efficiency of the Yangtze River Economic Belt is on the rise, on the contrary, the development of the Yellow River Basin is relatively slow. Through the difference analysis, it is found that the green transition efficiency of the manufacturing industry in the Yellow River Basin is lower than that of the Yangtze River Economic Belt, and the difference of the Yellow River Basin is larger than that of the other provinces.
