摘要

Agricultural modernization is an inherent requirement for the high-quality development of agriculture. High-standard farmland construction (HSFC), as one of the most typical modes for sustainable farmland development in China, plays a significant role in promoting agricultural modernization. This study first constructs a more practical evaluation index system for agricultural modernization, which is used to measure the agricultural modernization level (AML) of 278 cities in China from 2013 to 2022. Next, the fixed effects model, mediated model, and threshold model are sequentially employed to analyze the impact mechanisms and nonlinear moderating effects of HSFC on AML. Finally, the spatial model is applied to examine the spillover effect and to identify the distance boundaries of this effect. The main findings are as follows: (1) AML is highest in eastern China and lowest in western China. (2) HSFC significantly contributes to the enhancement of AML. This effect is more pronounced in midland and western China, as well as in major grain-producing and agriculture-dominant cities. HSFC promotes AML by fostering the agglomeration of agricultural industries and large-scale farming. (3) HSFC exhibits a positive spatial spillover effect on AML. This effect diminishes sharply after 100 km and becomes negligible beyond 200 km.
