Abstract
The advancement of information technology has increased the need for estimating the market size of new industries that did not previously exist. Companies require market size estimations to pursue new business ventures, but these emerging markets are not yet mature, making it difficult to define the boundaries of sub-industries and systematically establish industry-related data such as corporate sales and operating profits. Therefore, this study explores methods for estimating market size using public data. The economic indicator data, which are industrial statistics public data released by the National Statistical Office, include monthly, quarterly, and yearly industrial statistics. Specifically, these data encompass economic indicators such as the Mining and Manufacturing Production Index, the Mining and Manufacturing Shipment Index, the Domestic Supply Index, and the Value Added by Industry. This study analyzed whether market size can be estimated through standardized panel data analysis, focusing on the future mobility sector, and estimated the market size for 2021 and 2022 through statistical significance tests. The results of the study confirmed the existence of interrelationships among economic indicator data in the future mobility sector, enabling market size estimation. However, it was found that if the annual data for economic indicators are insufficient, the temporal correlations among indicators may not be reflected, leading to significant errors in long-term market size predictions.
