On the Adoption of Genetically Modified Seeds in Developing Countries and the Optimal Types of Government Intervention
构建理论模型分析发展中国家农民对转基因种子的采用决策，研究补贴、研发鼓励、知识产权执法等政府干预对转基因覆盖率和国家福利的影响，并考虑政府通过支付许可费在国内分销转基因种子的可能性。
Given the proprietary nature of most genetically modified (GM) seed technologies, the question arises as to how farmers in developing countries can gain proper access. Based on empirical observations, a theoretical model is developed, focusing on farmers' adoption decisions in response to pricing strategies of a foreign monopolist and a domestic supplier of conventional seeds. Government interventions, such as seed subsidies, encouragement of R&D, and intellectual property rights (IPR) enforcement, and their effects on GM coverage and national welfare are analyzed. The possibility of the government obtaining a license to distribute GM seeds domestically through a transfer to the monopolist is also considered.
