Abstract:In order to improve the science and accuracy of the comprehensive analysis for photovoltaic (PV) industry, quantify the multi-level and multi- perspective evaluation , this article researches on the construction and application of PV development index model based on the multi-dimensional fusion of electric data and government data.First ,based on analyzing the development level of PV and its impacts on power grid and users’ income，a set of evaluation index system including popularization、coordination and economical efficiency is proposed. Next,considering subjective and objective factors , a weight model combining entropy weight method (EWM) and analytic hierarchy process (AHP )is constructed, and the weight of the index system is given dynamically. Finally，empirical analysis based on data of a prefecture-level city in Zhejiang Province is conducted，the results reveal the PV development level of each month in recent years, analyse the differences of development level and industry characteristics in different regions.Besides, some suggestions are made. Practical application shows that the research methods and results have referential significance on comprehensive evaluation、scientific layout and reasonable planning for government departments and industrial companies.
