Dynamic Evolution Characteristics of Water Resources Utilization Efficiency in China Under the Constraint of Triple Attribute Carrying Capacity

Based on the triple attribute constraints of "resource endowment, social economy, and ecological environment," this paper establishes the calculation model of water resource carrying capacity, creatively takes water resource carrying capacity as an input factor, constructs an SFA efficiency calculation model, and analyzes the dynamic evolution characteristics of water resource utilization efficiency by using panel data of 31 provinces in China from 2003 to 2017, using Kernel density estimation and Markov chain methods. The results show that: ① the water resources carrying capacity of most provinces in China was steadily increasing; Northwest China, North China, Northeast China, and central China were at a low level, and Southwest and South China were at a higher level; ② the water resources utilization efficiency of all provinces in China had maintained a stable growth, and the growth rate of the western region was larger than that of the central and eastern regions; ③ the dynamic evolution of China's water resources utilization efficiency had the phenomenon of multi-polarization and convergence, and some provinces had a gradient effect, which had club convergence characteristics, poor liquidity, and a prominent Matthew effect. In order to realize the coordination and coupling of water resources, society, and the environment; reduce the difference in utilization efficiency between regions; and improve the efficiency of water resources utilization, this paper provides suggestions to fully consider the water resource carrying capacity, coordinate the development strategy of water resource supply and demand in the whole country and region, and construct a water rights trading market. © 2021, Science Press.
