Abstract

Context Collaborative governance of pollution reduction and carbon reduction is one of the important issues in current ecological environment protection. Aims In order to promote the coordinated reduction of pollution and carbon emissions in the Yangtze River Delta region. Methods; This article uses panel data from four provinces and cities in the Yangtze River Delta from 2011 to 2020 to evaluate the order degree, internal coordination, and coordination degree of the composite system using a composite system coordination model. Key results The following conclusions were drawn: firstly, the orderliness of pollution reduction and carbon reduction subsystems in the Yangtze River Delta region is showing a slow upward trend; Secondly, the level of internal collaboration between the two subsystems is not significant; Finally, the coordination between the pollution reduction subsystem and the carbon reduction subsystem is at a relatively low level. Conclusions Overall, the orderliness of pollution reduction and carbon reduction subsystems in the Yangtze River Delta region is on the rise, but lacks coordination. Implications Promotion policies are put forward: overall optimization of regional target coordination, further improvement of region management system design, establishment of regional resource sharing mechanism and technological innovation system.
