The synergy between CO2 emission reduction and air pollution control in urban China under scale-oriented strategy: A perspective of efficiency

Abstract

At present, energy shortages and air pollution are of increasing concern worldwide. During the "14th Five-Year Plan" period, China will more firmly implement the green development strategy. In order to explore the synergistic emission reduction effects of urban greenhouse gases and air pollutants under different strategies, this paper takes 30 major cities in China from 2011 to 2019 as the research object, and analyses the input-output performance of 30 cities under the scale-oriented strategy. The empirical results show that most large cities in China are still in a state of low efficiency and insufficient growth momentum.
