摘要

Grasping the current situation of green development in the Pearl River Basin can provide ideas for deciphering the high-quality development of the Pearl River Basin, and provide Chinese experience for the governance and protection of the world's great rivers. This paper takes 47 prefecture-level cities in the Pearl River basin (PRB) as the research object, measures and analyzes the green development efficiency (GDE) through the Super-SBM model with undesired output, and explores the influencing factors of GDE in the PRB with the help of Tobit model. The study found that: First, the level of GDE of PRB shows an N-shaped change, and most of the GDE in the PRB is in a relatively ineffective state. Second, the GDE of the PRB exists as an obvious differentiation phenomenon, and the regional development is extremely unbalanced. During the study period, the kernel density curve of GDE in the PRB showed an obvious double-peak coexistence phenomenon, and the height difference between the main and side peaks gradually increased with time. Last, Economic development (ED), industrial structure (IS), foreign capital utilization (FCU), and environmental regulation (ER) can contribute to the improvement of the GDE of PRB. At the same time, the impact of the technological level (TEC) on the GDE of PRB is negative, indicating that technological innovation has not become the source of growth of the GDE of PRB. Therefore, it is suggested that the ecological protection and high-quality development of the PRB should be upgraded to a national strategy at the national level, and the Pearl River Commission should make a unified deployment for the green transformation and development of the PRB. All regions in the PRB should have global thinking and coordinated development, proceed with the modernization of the governance system and governance capacity, continuously narrow the regional gap, and improve the efficiency of green development. Strengthen support for scientific and technological innovation, build a river basin ecological industry system, and promote green development and transformation.
