Economicapproachtothedemand-drivenR & DinminororIocaIspecificagriculturalproducts

从理论上讲，R&D受到知识产权的激励。由于最近加强的知识产权增加了研发的交易成本，公共投资作为一种研究机构受到了关注，特别是对小农或地方特有作物的开发。在本研究中，我们调查了消费者对北海道或东京农产品的偏好。土豆是东京农业最重要的当地农作物之一，一年四季都在学校午餐中使用。面包小麦是新开发的地方专用型小麦，由于当地农业的准公共性质，也将受到当地消费者的需求。

Theoretically, R & D is encouraged by the intellectual property rights(IPRs). Since the recent strengthened IPRs increase the transaction cost of R & D, public investment has become paid attention as a research institution, especially for the development of minor or locally specified crops.In this research, we have investigated the consumer preference toward Hokkaido or Tokachi agricultural products. Potato, one of the most important locally produced crops in Tokachi agriculture, is used in school lunch for whole year. The bread wheat, newly developed local specific type wheat, will also be demanded by local consumers because of quasi-public nature of local agriculture.
