Coupling coordination between producer services development and low-carbon economic transformation in china: spatial differences and forecasts

This study employs the coupling coordination model, the Dagum Gini coefficient, and the grey GM(1, 1) model to examine the coupling coordination degree (CCD) of producer services development and low-carbon economic transformation (PSLE). The research finds that the CCD of PSLE in China has been steadily increasing and has undergone a change process from “on the verge of imbalance” to “primary coordinated”. The CCD of the three major regions, from largest to smallest, are the eastern, central, and western regions. The CCD of the six major industries has also increased, but the two systems of high-end PSLE do not have a high overall CCD. Spatial difference analysis results indicate that the spatial differences of CCD in PSLE continue to expand on the whole, mainly reflected in regional differences. Prediction results further indicate that the CCD of PSLE is expected to continue its growth trend in the next five years, but it remains in the “primary coordination” stage. The CCD of the three major regions and six major industries has also increased, but it shows differential characteristics in terms of stage leaps. The article’s conclusion offers references for fostering the coordinated evolution of PSLE systems and attaining sustainable development.
