Investigating the coordination between ecological and economic systems in China’s green development process: a place-based interdisciplinary evaluation

Abstract

Harmonizing human activities with the natural environment has received much attention as a development goal and is a longstanding pursuit of human society. In this study, we investigated the sustainability of green development from the perspective of the coordination between economic and environmental subsystems at the place-based scale, with 290 cities in China as research objects. An interdisciplinary method combining an improved data envelopment analysis model and Lotka-Volterra model was conducted to examine the two subsystems’ development efficiency and their correlation (i.e., mutualism, commensalism, amensalism, sacrifice, competition, independence). The results indicate that one-third of the cities’ economic and environmental subsystems are in a mutualistic state, with a relatively stable social-ecological system. However, the two subsystems are in a state of competition in one-fourth of the cities, with rather intense vulnerability, where the harmonious coexistence of humans and nature is facing more significant challenges. In addition, vulnerability of the social-ecological system in economically developed cities shows substantial polarization. The two subsystems in most of these cities are in mutualism or amensalism relations, whereas the social-ecological system in economically underdeveloped cities shows even greater vulnerability.
