【摘要】 本文以我国生物技术的代表———转基因抗虫棉为案例 ,从其对生产者、社会福利分配的影响和技术的外部性三方面概述了相关的研究方法。其中对生产者影响研究方法的重点是对农药生产率的测定 ,同时讨论了规避风险和生物过程与农药使用的关系 ;社会福利分配的研究方法论述了采用完全市场模型的必然性 ;技术的外部性则讨论了转基因作物的收益评估与外部成本。最后针对上述方法的特点和不足 ,提出进一步研究的方法展望。更多还原

【Abstract】 This paper looks the transgenic pest resistant cotton as a case of Chinese biotechnology, and summarizes relevant research methodologies from three aspects including its impacts on production, social welfare distribution and its externalities. The crucial research method of its impacts on production is the measuration of pesticides’ productivity, here also discusses the relationship between risk aversion and biological process and pesticides use. The method on social welfare distribution discusses the inevitability for the application of complete market model on Chinese cotton market. The technological externality discusses the benefit evaluation and external costs. According to the characters and shortages of above methodologies, this article puts forward to the method prospect for further research.更多还原
