Spatial Characteristics of Coupling Development of Ecological Protection and Agricultural Economy in China

Abstract

[Purpose] To explore the coupling coordination evolution law of China’s agricultural ecological environment and economic development, and provide reference and a decision-making basis for coordinating the relationship between the ecological environment and agricultural economy in the process of China’s agricultural economic development. [Method] Based on the coupling coordination mechanism between ecological protection and agricultural economy, this paper constructs an evaluation index system for agricultural ecological environment and economic growth, and explores the spatiotemporal evolution law of the coupling coordination between the agricultural ecological economic system in China’s 31 province administrative regions from 2010 to 2020. [Result] From 2010 to 2020, the overall development level of China’s agricultural ecology and economy was gradually improving; the level of coupling coordination increased significantly before 2015, but then the growth remained stable; the global Moran’s I index of coordination is “first descending and then ascending”; and the LISA cluster diagram of the local Moran’s I index was “east high and west low” before 2015, but then “west high and east low”. [Conclusions] The level of coupling and coordination development of agricultural ecological economic systems in various provinces has steadily increased, but the development level between regions is uneven. It is necessary to strengthen natural disaster management, increase investment in agricultural development, and enhance regional cooperation between regions to promote high-quality and green sustainable development of agricultural ecological economic systems. [Innovation] A new evaluation index system was constructed, the indicator data are complete and comprehensive (including data from 31 different province administrative regions from 2010 to 2020), and the analysis perspective is rich and diverse (through the comparison and changes of the time and space perspectives, the results from different perspectives were comprehensively analyzed). This paper finds that the coordination degree shows significant periodicity with 2015 as the boundary; the growth rate is “west fast and east slow”.
