A Study on the Heterogeneous Effects and Pathways of Technological Innovation on High Quality Agricultural Development under Water Resource Constraints
For ecologically fragile areas with insufficient water resources,it is of great significance to clarify the impact and mechanism of technological innovation on the quality of agricultural development under different water resource con-straints in the face of the goal requirements of high output and high-quality development of agriculture in the new era.It can reduce the constraints of ecological resources on agricultural development,improve the matching and contribution of techno-logical innovation,and enhance the level of high-quality agricultural development.Taking 12 cities in Inner Mongolia as an example,based on panel data at the municipal level from 2008 to 2021,this paper objectively measures the level of high-quality agricultural development in different regions,and introduces a constrained dependent variable model and a general-ized moment estimation model to quantitatively identify the heterogeneous impact and mechanism of technological innovation on high-quality agricultural development under different water resource constraints.The results indicate that:①Technological innovation can significantly promote high-quality agricultural development under different water resource con-straints,and the impact of technological innovation on high-quality agricultural development in strong water resource con-straint areas is five times that in weak water resource constraint areas;②The impact of technological innovation on the high-quality development of agriculture has a time lag,and the impact of technological innovation talents is also significant;③Mechanism analysis shows that technological innovation mainly promotes high-quality agricultural development by promoting"water-saving"and"efficiency enhancement"of water resources.Finally,the article suggests strengthening investment in technological innovation,establishing support policies for technological innovation that adapt to different water resource con-straints,alleviating the problem of insufficient water resources through technological innovation measures,achieving effective support and guarantee of water resources for agricultural development,and promoting sustainable agricultural development.
