【Abstract】A simple and robust approach to predict the spillover effects of emerging technologies enables proper formulation of investment strategies. In this study, we propose the method in order to detect industry sectors impacted by the spillover effect of emerging technologies in their early stage. The method integrates patent analysis with input-output analysis to model knowledge spillover among industrial sectors and has the following three steps. The first is an analysis of technological features in industry sectors. Using the IPC group of patents, we characterized each industrial sector by technological features. The second is an analysis of technological features in a given emerging technology. The third is a similarity analysis of the technological features between emerging technology and industry sectors. In this paper, we conducted a case study on blockchain technology. We demonstrated the effectiveness of the proposed method by comparing the results with the existing reports. We found that the predictive performance became the highest when we used an industrial sector-normalized matrix in patent analysis and producer's price table in input-output analysis. This method is expected to be used for the early detection of spillover effects of emerging technologies.
