随着经济发展与环境保护之间矛盾的日益突出，绿色发展己成为世界各国工业发

With the increasingly prominent contradiction between economic development and environmental protection, green development has become an inevitable choice for the industrial development of all countries in the world. Under the new normal of economic development, the industrial development of Fujian Province is at <br>an important stage of structural transformation and upgrading and power shifting. At the same time, it is also facing the important task of energy saving, emission reduction and ecological province construction. How to achieve the "win-win" of industrial transformation and upgrading and environmental protection has become a major problem facing Fujian Province in achieving sustainable industrial development. Ecological efficiency is an important indicator to measure the degree of coordinated development of industry and the environment. Improving industrial ecological efficiency is the key to promoting industrial green development. Therefore, improving the industrial ecological efficiency of Fujian Province has important theoretical value and practical significance for realizing the coordinated development of industry and the environment in the whole province, building the first demonstration zone of ecological civilization, and creating a "fresh Fujian". <br>This paper takes nine cities in Fujian Province as the research object, and takes industrial eco-efficiency as the main line of research. First, aiming at the shortcomings of the traditional DEA method, construct an SBM industrial eco-efficiency evaluation model based on undesired output and a dynamic evaluation model based on Malmquist-Luenberger index Secondly, the industrial ecological efficiency of Fujian Province from 2008 to 2018 was statically evaluated and dynamically decomposed, and the a-convergence and absolute Q convergence models were used to test the convergence of industrial ecological efficiency in Fujian Province. At the same time, based on the analysis of the mechanism of industrial eco-efficiency influencing factors, a Tobit panel regression analysis model is constructed to carry out empirical research on the influencing factors of industrial eco-efficiency: Finally, according to the results of the empirical analysis, from the industrial structure, technological innovation , Opening to the outside world, environmental regulation, and regional development, and put forward countermeasures and suggestions to improve the industrial ecological efficiency of Fujian Province.

With the increasing contradiction between economic development and environmental protection, green development has become the inevitable choice of industrial development in all countries of the world. Under the new normal of economic development, Fujian Province's industrial development is in the process of structural transformation and upgrading<br>With the important stage of power shift, at the same time facing the responsibility of energy conservation and emission reduction and ecological province construction. How to realize the "win-win" of industrial transformation and upgrading and environmental protection has become a major problem for Fujian Province to achieve sustainable industrial development. Ecological efficiency is an important index to measure the degree of coordinated development of industry and environment, and improving industrial ecological efficiency is the key to promote industrial green development. Therefore, it is of great theoretical value and practical significance to improve the industrial ecological efficiency of Fujian Province to realize the coordinated development of industry and environment in the province and to build a pilot demonstration area of ecological civilization and to build a "fresh Fujian".<br>Based on the shortcomings of the traditional DEA method, the SBM industrial eco-efficiency evaluation model based on non-expected output and the dynamic evaluation model based on the Malmquist-Luenberger index are constructed in this paper. Secondly, the static evaluation and dynamic decomposition of industrial ecological efficiency in Fujian Province from 2008 to 2018 were carried out, and the convergence of industrial ecological efficiency in Fujian Province was tested by a-convergence and absolute Q convergence model. At the same time, based on the analysis of the mechanism of the factors influencing industrial ecological efficiency, the Tobit panel regression analysis model is constructed, and the empirical research on the factors influencing the industrial ecological efficiency is carried out: Finally, according to the empirical analysis results, the countermeasures to improve the industrial ecological efficiency of Fujian Province are put forward from five aspects, such as industrial structure, scientific and technological innovation, opening-up level, environmental regulation and regional development.

With the increasingly prominent contradiction between economic development and environmental protection, green development has become the inevitable choice of industrial development in the world.
