Abstract

Land resources and water resources are the important material basis of economic and social development, and their pattern determines the pattern of development. Based on the panel data of the Chengdu–Chongqing Economic Circle from 2011 to 2018, this paper evaluates the matching degree of water and land resources, and their respective matching degrees with the economic development in the Chengdu–Chongqing Economic Circle with the Gini coefficient method. Based on the two-way fixed effect model, an extended Cobb–Douglas production function model is established to analyze the sensitivity of economic growth to land and water factors. In addition, the restriction degree of water and land resources to the economic development of the Chengdu–Chongqing Economic Circle is measured quantitatively by using the growth damping coefficient. The results show that the water and land resources and economic development of the Chengdu–Chongqing Economic Circle have a high matching degree, but the inner cities have a great difference. The contribution of water resources to economic growth is greater than that of land resources. Both of them have a little growth drag, which shows that industrial development has disposed of the dependence of water and land resources. The development of the Chengdu–Chongqing Economic Circle needs to play the role of technological progress in promoting economic growth, and at the same time optimize the use of water and land resources to reduce its constraints on the economic growth. Finally, the policy suggestions of matching water and land resources and economic growth in different regions are put forward.

Highlights

Natural resources are a key factor in the economic development of all countries, of which water and land resources are the most basic natural resources
The damping effect of water and land resources on the economic growth and the matching degree of water and land resources and the economy in the Chengdu–Chongqing Economic Circle were studied in depth
The restraining effect is often realized through the high contribution of capital in the industry, the high growth of the population and the dependence of the economy on water and land resources

Summary

Introduction

Natural resources are a key factor in the economic development of all countries, of which water and land resources are the most basic natural resources. The area, quality and development degree of land resources determine the production efficiency, which is the basis of human survival and economic activities. The abundance of water and land resources determines the regional ecological environment quality and population carrying capacity, and affects the speed of the regional economic growth. The Heckscher–Ohlin theory and the bulk product theory believe that the use of resource advantages can effectively promote regional economic development. With the continuous growth of the population, the shortage of water resources has become an important factor restricting the sustainable development of the environment and society [4]. Large amounts of water and land have long been exploited for fuel, rapid economic growth and an increasing demand has intensified water and soil loss, posing huge risks to the economy [6,7,8]
