4th 산업혁명 전후 기술 간의 질적 유의성 실증을 통한 기술 동태 연구 - 기술 다양성을 중심으로

The European Patent Office analyzed the quantitative dynamics of technology patents related to the 4th industrial revolution(hereinafter referred to as 4th IR) on a global scale in a time series perspective, and based on these analysis results, the rapid spread of the 4th IR technologies were defined as starting in 2010. Going one step Further from the results of these quantitative studies, this study dealt with the changes in the qualitative dynamics of knowledge assets (based on technology patents) around 2010 from the perspective of diversity. Firstly, it was confirmed from previous studies that the qualitative characteristics of technology in the 4th IR period are convergence and this convergence is linked to technological diversity. On the basis of this fact, the significance of qualitative changes in technology before and after the 4th IR technology spread (2010) was analyzed throughout the industry from the perspective of the diversity index. As a result of the analysis, qualitative changes based on diversity in technology increased significantly before and after 2010 in pharmaceutical·bio-health and electric·electronic·IT industries, and industries with significant increase in diversity accounted for a majority of the stock market's market capitalization than industries that did not. These facts suggest that pharmaceutical·bio-health and IT·electricity·electronics industries are leading convergence through the increase in diversity during the 4th IR period and these industries lead the value of the entire industry. In this study, the change of qualitative characteristics in technology before and after 2010(when 4th IR technology exploded) were demonstrated by industries on the basis of technological diversity which is extracted from actual patent technology information, and compared with the current distribution of market capitalization (enterprise market value) by industry sector. In the era of 4th IR technology, it is meaningful that this study demonstrated the direction of ‘corporate technology management strategies’ & ‘qualitative research related to knowledge assets’ from diversity that is based on actual technology data, and presented the basis for study between technology diversity and corporate value.
