Abstract

In the rapid process of urbanization in China, arable land resources are faced with dual challenges in terms of quantity and quality. Starting with the change in the coupling coordination relationship between the input and output on arable land, this study applies an evaluation model of the degree of coupling coordination between the input and output (D_CCIO) on arable land and deeply analyzes the recessive transition mechanism and internal differences in arable land use modes in 31 provinces on mainland China. The results show that the total amount and the amount per unit area of the input and output on arable land in China have presented different spatio-temporal trends, along with the mismatched movement of the spatial barycenter. Although the D_CCIO on arable land increases slowly as a whole, 31 provinces show different recessive transition mechanisms of arable land use, which is hidden in the internal changes in the input–output structure. The results of this study highlight the different recessive transition patterns of arable land use in different provinces of China, which points to the outlook for higher technical input, optimized planting structure, and the coordination of human-land relationships.

Highlights

  • The world has not witnessed such rapid urbanization as that which has taken place over the past several decades in China [1]

  • To fulfill the research gaps, this study aims to further explore the law of the recessive transition mechanism of arable land use based on the input-output perspective

  • After determining the weight of each indicator using the entropy method, we can calculate the indexes of the input–output subsystem using the following process

Summary

Introduction

The world has not witnessed such rapid urbanization as that which has taken place over the past several decades in China [1]. Along with the urbanization process, China’s economic structure is undergoing rapid transition. The proportion of China’s nonagricultural economy (the ratio of the GDP of the secondary and tertiary industries in the total national GDP) increased from 72% in 1978 to. 93% in 2018, showing a significant shift in economic development focus towards nonagricultural industries. In this vast wave, the use of arable land is facing various challenges. By 2018, more than 200 million rural residents had migrated to urban areas, indicating a large transition of farmers’ livelihood from traditional agricultural production to employment in secondary and tertiary industries in cities [3,4]. Along with a rapid expansion of construction land area
