The Synergistic Effect of Carbon Reduction,Pollution Abatement,Green Expansion and Economic Growth:A New"Four In One"Evaluation Framework and Measurement Method
In China's quest to build an ecological civilization,the collaborative advancement of carbon reduction,pollution abatement,green expansion,and economic growth stands as a strategic imperative.This article adopts a scientific,typical,and user-friendly approach,employing four key indicators-carbon productivity,environmental quality index,ecological capital service value per unit area,and per capita GDP-to encapsulate the facets of carbon and pollution reduction,green expansion,and economic development.Drawing inspiration from the methodology behind the United Nations Human Development Index,we've synthesized the"Four in One"development index,which consolidates the evaluation and analysis of 253 Chinese cities.Our analysis not only benchmarks the overall development levels and geographic distribution of these cities but also categorizes them into four distinct types-high growth-high green,high growth-low green,low growth-high green,and low growth-low green-based on the interplay between economic growth and green development.The"Four in One"index serves as an enhancement to the evaluation and accounting frameworks for green development,offering a universal and scalable tool that can be applied across various regional levels to dynamically monitor the developmental trajectories of cities.
