Innovation and Entrepreneurship: A first look at linkage data of Japanese patent and enterprise census
This paper presents the results of a comprehensive analysis of the innovative activities of the entire population of Japanese firms by using a linked dataset of Establishment and Enterprise Census and the IIP Patent Database (JPO patent application data). As of 2006, it was found that about 1.4% of about 4.5 million firms filed patents, and substantial patenting activities were found not only in the manufacturing field but also in a wide range of fields such as B2B services and financial sectors. In addition, a firm's survival and growth are regressed with patenting and open innovation (measured by joint patent application with other firms and universities), and it is shown that innovative activities measured by patenting are positively correlated with such firm performance. It is also found that the relationship between patents and the survival rate is stronger for larger firms, while that between patents and firm growth is stronger for smaller firms.
