Identification of influencing factors and evaluation of island green development index based on DEMATEL-AHP model
Green development of island is an important way and inevitable requirement for protecting the marine ecological environment and building China into a maritime power.This paper puts forward the concept of island green development index(IGDI),selects 22 indexes from 6 aspects,including energy consumption and resource utilization,environmental management and governance,environmental quality and safety,economic growth quality,green living standards,and public satisfaction,the evaluation index system of IGDI is constructed,the method of combining DEMATEL and AHP is used,the key influencing factors are identified,and 12 island counties(cities and districts)(hereinafter referred to as"island counties")are taken as examples to conduct a comprehensive evaluation and analysis.The results show that:(1)The influence degree of"the economic agglomeration degree"(2.15)and"energy consumption per unit of GDP"(2.01)is more than 2,and the influence degree of the proportion of investment in environmental pollution control to GDP,carbon emission intensity,ecological damage and environmental pollution,the degree of island land development,the proportion of added value of the tertiary industry,the disposal rate of domestic waste and all the other indicators are more than 1,reflecting environmental management and governance,energy consumption and resource utilization,and the quality of economic growth are the keys to determining the effectiveness of green development of islands.(2)The average evaluation value of IGDI of 12 Island counties is 74.37,with the highest value in Shengsi County(88.24)and the lowest value in Chongming District(65.57).It reflects that the overall level of green development of our country's islands is not high,and there are significant differences between islands.(3)To promote the green development of islands,is necessary to adhere to the people-centered development philosophy,strengthen the comprehensive management of islands based on the concept of green development,promote the green transformation and upgrading of island industries,implement ecological improvement and restoration of the island,and enhance the carbon sink capacity of island ecosystems.
