农业水价综合改革对中国种植业高质量发展的影响与作用机制OA

High-quality development of the planting industry is a fundamental support and key pathway for build-ing an agricultural powerhouse in China.Assessing how agricultural water price reform influences the industry's high-quality development can provide evidence to guide the further deepening and effective implementation of re-form policies.From an input-output perspective,this study examines the effects and mechanisms of agricultural water price reform on the high-quality development of China's planting industry and measures the level of high-quality development of planting industry.We construct an index to measure the level of high-quality development and employ a staggered difference-in-differences model to test the policy's impacts,mechanisms,and regional heterogeneity.The results show that(1)From 2011 to 2022,the level of high-quality development in China's planting industry increased overall,with clear spatial disparities:eastern coastal provinces and northern ma-jor grain-producing areas performed better,and a stepwise decline is observed from central to western re-gions.(2)The findings also suggest that agricultural water price reform significantly promotes high-quality devel-opment,but the effects vary across regions,with stronger effects in major grain-producing areas and southern re-gions.(3)The reform advances high-quality development by encouraging agricultural water conservation,opti-mizing cropping structures,and increasing the adoption of water-saving irrigation technologies;these mecha-nisms also exhibit marked regional heterogeneity.These findings suggest that future reforms should adopt a differ-entiated framework for deepening implementation,tailored to regional conditions,to better support high-quality development of the planting industry.
