Case Study on Indigenous Rice Germplasm Conservation in Yuanjiang Based on Stakeholder Theory

Abstract Native rice, which can grow at higher altitudes, contains high quality genes and genetic characteristics, but its distribution is worrying. Therefore, conservation of native rice is of great significance both from the perspective of germplasm resources conservation and economic value.This paper introduced the stakeholder theory, and based on the results of the three-party evolutionary game model involving local government, enterprises or cooperatives, and farmers, put forward suggestions for wild rice conservation in Yuanjiang County, and provided references for the conservation and sustainable utilization of agricultural biodiversity and genetic resources in food and agriculture in other areas.The results showed that in the short term, the protection of native rice is in urgent need of encouragement, support, publicity and guidance from local governments. There is a close relationship between government subsidies to enterprises and farmers and their enthusiasm for buying and planting native rice.When the subsidy coefficient of government to enterprises is small, enterprises tend to "not purchase". The higher the subsidy coefficient is, the faster the enterprises reach evolutionary stable state, but the faster the government and farmers reach evolutionary stable state slows down.The higher the subsidy coefficient, the faster the farmers, enterprises and cooperatives reach the evolutionary stable state, but the slower the government reaches the evolutionary stable state. When the government's subsidy coefficient to farmers is large, farmers may tend to "do not plant" and the government tends to "do not encourage".Therefore, the government should carefully weigh the subsidies given to enterprises, cooperatives and farmers, and take into account the local financial situation and the status quo of the restoration of native rice planting and in-situ protection.
