RESEARCH ON THE IMPACT OF AGRICULTURAL INSURANCE ON AGRICULTURAL CARBON PRODUCTIVITY
This study aims to explore whether agricultural insurance can achieve dual promotion of agricultural economic development and carbon reduction,thereby improving agricultural carbon productivity.Based on the panel data of 30 provinces,cities or autonomous regions(excluding Hong Kong,Macao,Taiwan,and Tibet)in China from 2008 to 2020,a two-way fixed effect model and a mediation effect model were constructed to empirically test the impact of agricultural insurance on agricultural carbon productivity and its mechanism.The results were listed as follows.(1)Agricultural insurance was conducive to improving agricultural carbon productivity,that was,with every 1%increasing in the development level of agricultural insurance,agricultural carbon productivity increased by 0.049%on average.(2)From the perspective of its mechanism,agricultural insurance improved agricultural carbon productivity by promoting agricultural industry agglomeration and agricultural technology progress,and the intermediary effect accounted for 39.1%and 24.5%respectively.(3)Further discussion found that there was a single threshold effect of the proportion of agricultural output value on the impact of agricultural insurance on agricultural carbon productivity,the threshold value was 0.012 5.When the proportion of agricultural output value was lower than the threshold value,the role of agricultural insurance on agricultural carbon productivity was not obvious,while when the proportion of agricultural output value exceeded the threshold value,agricultural insurance would have a significant role in promoting agricultural carbon productivity.Therefore,to further strengthen the environmental positive externalities of agricultural insurance,the government should strengthen policy support to improve the level of security,implement differentiated subsidies to promote large-scale production,improve insurance clauses,and explore innovative varieties.
