The Effect and Evolution Law ofInnovation-Driven Strategy on Industrial Environmental Efficiency

In this study, taking Anhui Province as an example, the comprehensive indices of industrial environmental efficiency and technological innovation are evaluated by means of the principal component analysis method. Next, the marginal effect of technological innovation on industrial environmental efficiency is calculated via partial least squareregression analysis. Then, based on the optimal fitting regression analysis method, the evolution law between technological innovation and industrial environmental efficiency is investigated. The results show the following: (1) The indices of industrial environmental efficiency and technological innovation rose to 71.28 and 83.63 in 2016 from 47.17 and 43.63 in2005, respectively. (2) Technological innovation has a positive promoting effect on the improvement of industrial environmental efficiency, and its marginal elastic coefficient is 0.0051, while the industrial structure is a constraint factor for the weakness of industrial environmental efficiency, and its marginal elastic coefficient is -0.0014. (3) The evolution law of positive exponential function is shown between technological innovation and industrial environmental efficiency, in which the enhancement of technological innovation ability is conducive to the further improvement of industrialenvironmental efficiency. Based on the research results, corresponding policy suggestions are proposed regarding how to promote technological innovation and avoid the weakness of industrial structure.
