黄河流域生态福利绩效与工业企业绿色创新效率耦合协调性研究

Study on the Coupling and Coordination of Ecological Welfare Performance and Green Innovation Efficiency of Industrial Enterprises in the Yellow River Basin

运用超效率DEA模型和耦合协调度模型,对黄河流域2010—2020年生态福利绩效与工业企业绿色创新效率的耦合协调性进行了深入探讨。结果显示,两者绩效总体呈上升趋势,但绿色创新效率提升显著快于生态福利绩效。不同省区绩效差异明显,部分省区生态福利水平持续下降。耦合协调度整体呈下降趋势,其中甘肃波动较大,而青海较平稳。生态福利绩效与绿色创新效率发展不同步,且不协调性有上升趋势。西部省份耦合协调水平相对较高,而中东部省份偏低。为此,建议加强政策引导,促进两系统协调发展,以实现黄河流域的可持续发展。

This study employed the super-efficiency DEA model and coupling coordination degree model to investigate the coupling coordination between ecological welfare performance and green innovation efficiency of industrial enterprises in the Yellow River Basin from 2010 to 2020.The results revealed an overall upward trend in both performances,with green innovation efficiency significantly outpacing ecological welfare performance.Significant differences in performance across provinces were observed,with some experiencing continuous declines in ecological welfare.The coupling coordination degree generally declined,with significant fluctuations in Gansu and relative stability in Qinghai.Ecological welfare performance lagged behind green innovation efficiency,exhibiting a rising trend of incongruity.Western provinces exhibited relatively higher coupling coordination levels,while those in central and eastern regions were lower.Consequently,policy guidance is recommended to promote coordinated development of both systems,thereby achieving sustainable development in the Yellow River Basin.
