Evaluation on sustainable development of wind power industry in Jiangsu province based on comprehensive integration method

Based on the data of intertidal wind power industry in Jiangsu province from 2012 to 2015, and the actual development situation of intertidal wind power industry in Jiangsu province, the evaluation index system of sustainable development of intertidal wind power industry in Jiangsu province was established, and the sustainable development level of intertidal wind power industry was evaluated.The sustainable development efficiency of the intertidal wind power industry was measured from the perspective of input-output by using data envelopment analysis (DEA).The results showed that from 2012 to 2015, the comprehensive index of sustainable development of intertidal wind power industry in Jiangsu province increased from 0.345 to 0.605 and the average integrated efficiency of sustainable development was 0.916 which was at a relatively high level.From 2012 to 2013, the situations of ineffective sustainable development, excessive input and insufficient output occurred.However, the sustainable development efficiency has entered the stage of benign development from 2014.According to the influence analysis of the input index, we can see that the economic input index has the greatest influence on the input-output efficiency, while the scientific and technological innovation input index has the least influence.So we need to further strengthen the investment in science and technology and talent attraction.
