Abstract: Based on the micro-survey data of 2 628 farmers in 26 districts and counties in Jiangsu Province in 2020, the effect and mechanism of the adoption of green production technology influenced by farmers' entrepreneurship were empirically tested by measuring methods such as poisson regression with endogenous treatment effects, endogenous switching regression and intermediary effect model. The results show that: (1) Farmer entrepreneurship can significantly promote the adoption of green production technology by farmers, and this conclusion is still supported after eliminating endogenous and selective bias problems. (2) Farmers' entrepreneurship can promote the adoption of green production technology by expanding social capital, strengthening risk appetite, establishing environmental protection awareness and enhancing financing capacity. (3) Further analysis of the heterogeneity of entrepreneurship types proves that agricultural entrepreneurship plays a greater role in promoting green production behavior than non-agricultural entrepreneurship. In view of this, it is suggested that the grass-roots government should increase its support for the "mass entrepreneurship and innovation" policy, implement precise entrepreneurial guidance according to the basic endowment of farmers, help farmers who have long been engaged in green agricultural production grow into new business entities such as family farms and large grain-planting farmers, and recommend them radiate green production technology outwards. At the same time, agricultural entrepreneurs are encouraged to rely on the local agricultural technology extension service stations to establish green production technology promotion and discussion network, and to lead ordinary farmers to contact and integrate into the green production network structure.
