Development of Knowledge-Based Economic Indicators to Analyse the Decisive Factors of Knowledge Stock

近年来，知识作为资源的重要性在宏观经济和企业增长机制的研究领域受到了重视。然而，由于无形资产的特性很难衡量知识，目前的许多研究都局限于对这一概念的探讨。为了解决这一问题，本研究开发了知识存量决定因素相关指标。为了收集基础数据以制定指标，对日本500家公司进行了问卷调查。此外，可能将数据库用于智力成果(论文、专利等)都进行了检查。根据这些测试结果对知识存量进行了测量。分析了知识存量及其与其他各项经济指标的关系。

Recentry, the importance of knowledge as the resource has been paid to attention in the research field concerning the mechanism of the growth of the macro economy and the firms. However, because it is difficult to measure knowledge with the characteristics of the intangible assets, many of current researches have been limited to discuss the idea. To solve this problem, this research developed the indicators which the decisive factors of the knowledge stock concerned. To collect basic data to develop the indicators, a questionnaire survey for the Japanese 500 companies was conducted. Moreover, possible use of the data bases for intellectual results (thesis, patent, etc.) were examined. The knowledge stock was measured based on those examination results. Thus, the knowledge stock and the relation to other various economic indices were analyzed.
