Coordination Development of"Water-Energy-Food"System in China's Agriculture and Its Influencing Factors
This article aims to clarify the connotation and influencing factors of the coordination development of the"water-energy-food"system of agriculture.Based on the panel data of 30 provincial-level regions in China from 2000 to 2021,this article constructs an evaluation index system for the coordination development of the"water-energy-food"system of agriculture.Various models including coupling coordination,spatial autocorrelation,spatial Markov chain,and spatial econometrics are utilized to explore spatial-temporal evolution and influencing factors of the coordination development level of the"water-energy-food"system of agriculture.The results indicate that:1)In terms of spatial-temporal evolution,the overall coordination development level of the"water-energy-food"system of China agriculture is relatively low,and shows a fluctuating upward trend and a uneven spatial distribution characteristic which is higher in eastern region than that in western region,followed by northeastern region and central region respectively.2)In terms of spatial correlation,the coordination development level of the"water-energy-food"system of China agriculture shows a significant positive spatial correlation,with obvious spatial agglomeration characteristics.3)In terms of influencing factors,urbanization level,agricultural operation scale,sci-tech innovation,fiscal support for agriculture,environmental regulations,and farmer income are all conducive to the improvement of the coordination development level of the"water-energy-food"system of local agriculture.Urbanization level,agricultural operation scale,and sci-tech innovation have significant positive spatial spillover effects.
