Can Urban Green Innovation Promote Collaborative Emission Reduction of CO_2 And Air Pollutants? ‐‐ Based on the Study of Low‐carbon Pilot Cities in China

The situation of carbon emission and haze pollution in China is severe. Collaborative emission reduction has become a powerful means to deal with complex pollution problems. To tackle environmental pollution and wean the economy off excessive reliance on carbon, China has launched low‐carbon pilot projects in three batches in several places. This paper selects panel data of 66 pilot low‐carbon cities in China from 2005 to 2017, uses binary dependent variable index to define urban CO_2 and PM2.5 collaborative emission reduction, and discusses the impact of urban green innovation capability on collaborative emission reduction. The results show that: (1) When multiple factors are excluded, urban green innovation ability significantly promotes the collaborative emission reduction of CO_2 and atmospheric pollutants. (2) Urban green innovation has the best effect on collaborative emission reduction of CO_2 and soot, followed by SO_2, wastewater and PM_(2.5). (3) The research and development cycle is shorter and the low‐quality green innovation which is easy to put into actual production is more obvious. Therefore, we should actively promote green technology innovation nationwide, set up more low‐carbon pilot areas, give full play to the role of green innovation in haze control and carbon reduction, and promote the realization of the dual carbon goal and haze control.
