Outline
Based on the ecological-technical-economic synergy path, the super-efficiency SBM model combined with the GML index method was used to accurately measure the green total factor productivity in Xinjiang, and systematically evaluate the green development level of Xinjiang mining industry cluster. The results show that the green total factor productivity of mining industry in Xinjiang is lower than the national average, and the lack of technological innovation ability is an important factor restricting the development of mining industry in the region. Through the method of location entropy, the degree of industrial agglomeration of mineral resources in Xinjiang is quantitatively analyzed, and finds that it presents the characteristics of "high agglomeration, low green and weak chain", and there is a phenomenon of "virtual fat" in the cluster. With the help of vector autoregressive model, the dynamic relationship between industrial agglomeration degree, green development level and regional economic growth is empirically analyzed. Among them, the green development level has a significant impact on the agglomeration degree of mining clusters. The synergy effect of green development level and industrial agglomeration degree is the core driving force of sustainable economic development, forming a positive feedback mechanism of "green technology-industrial agglomeration-economic efficiency". Based on this, it is proposed to build a "four-in-one" green development system with "ecological value-added, technological empowerment, network synergy and structural optimization" as the core, so as to provide practical countermeasures for the green and high-quality development of mining clusters in ecologically fragile areas.
