Abstract: Based on the panel data of 30 provinces in China from 2009 to 2018, a static and dynamic panel data model was established to explore the environmental effects of agricultural intellectual property protection from the perspective of international transfer of environmental technology.The results show that the environmental effect of the current period is not significant, but the environmental effect of the lagging period is significant. The relationship between the degree of protection of agricultural intellectual property and environmental technology spillover is nonlinear, and there is the optimal environmental effect value of the degree of protection of agricultural intellectual property.The protection of agricultural intellectual property rights has indirect positive impact on environmental technology spillover through foreign direct investment, R&D investment and human capital stock, while indirect negative impact on environmental technology spillover through international trade.The protection degree of agricultural intellectual property should be matched with the development of agricultural economy, the consumption ability of human capital to the new knowledge of agricultural environmental technology should be enhanced, the property right consciousness of the public should be cultivated, and the green design of the protection system of agricultural intellectual property should be strengthened.

Key words: degree of protection of agricultural intellectual property, environmental effect, optimal protection, the ability to consume new knowledge, multiple synergy of ecological interests
