The present paper aims to analyze causative factors, especially climate factors, for improvement of total factor productivity (TFP) in dairy and beef cow production in Japan by using the panel-data econometric method. Empirical results demonstrated that a 1℃ increase in summer temperature against spring brings about a 2.0-2.6 % reduction in TFP of the dairy sector, but no significant change in the beef cow sector. Regarding socioeconomic factors, knowledge capital stocks which were accumulated by annual research and development investment played an important role in improvement in both sectors' TFPs. Enlargement of average farm size had positive effects only in the dairy sector. Therefore, it is important to increase knowledge capital stocks for canceling out negative effects of future global warming.
