Abstract

<p>This paper conducted a quantitative analysis on the period of maintenance of the breeder's right and examined the possibility of use it as economic value evaluation index. The following two hypotheses were verified by the Kaplan Meier method and the discrete time logit model.</p><p>1) Since breeder's right is low in registration fee, right holders continue to maintain their rights until the expiration date of the duration specified by the law</p><p>2) If the right holders abandon the right before the expiration date, the tendency varies depending on the type of agricultural products and the attributes of the right holder</p><p>In the present study, the right holders judge maintaining the right or not based on the registration fee every year. Also, it is revealed that the difference between the type of agricultural products and the right holder attribute has an influence on the period of maintaining right.</p>
