Abstract: Agricultural insurance is an important means to promote the transformation of agricultural development from over reliance on resource consumption to green and sustainable development. The article constructs a panel data of agricultural input-output and polluting emission in 31 provinces of the whole country from 2001 to 2015, calculates green productivity of agriculture using GML index and decomposes it into green technical change and green technical efficiency, then empirically tests the influencing mechanism of agricultural insurance on green productivity of agriculture with system GMM. The main conclusions are as follows:agricultural insurance plays a significant role in promoting green technical change of agriculture while it has a significant inhibitory effect on green technical efficiency of agriculture. The promoting impact of agricultural insurance on green technical change of agriculture is larger than the inhibitory impact of agricultural insurance on green technical efficiency of agriculture, which makes it significantly promote green productivity of agriculture.

Key words: agricultural insurance, green productivity of agriculture, green technical change, green technical efficiency
