Research on Evaluation and Influencing Factors of Green Transportation Level Based on the DPSIR Model
In order to accurately and scientifically access the level of development of green transportation in mega-cities and investigate the key factors that hinder its progress,this paper utilizes the DPSIR(Driver-Pressure-State-Impact-Response)model to establish an initial evaluation index system for the development of green transportation in mega-cities.The indicators are weighted using the CRITIC-Entropy Weight Method.Besides,set pair analysis-variable fuzzy set model is utilized to establish the comprehensive evaluation model of green transportation level in mega-cities,while the obstacle degree model is employed to assess the factors hindering the development of green transportation in mega-cities.The results indicate that the state of green transportation in mega-cities can be categorized as"moderate"level,and its temporal progression exhibits a"wavy"pattern.The primary impediments hindering the growth of green transportation in these cities are the number of buses owned per 10,000 inhabitants and the urbanization level;the secondary obstacles include factors such as population density,road network density in built-up areas,the number of taxis owned per 10,000 people,per capita green space in parks,daily bus passenger volume,per capita road area,and the average concentration of inhalable particles.The conclusion of this study reveals the shortcomings of mega-cities in the process of green transportation development and provides theoretical support for the formulation of policies aimed at promoting such development.
