Abstract

In this paper, we examine multiple segments, conventionally analyzed from the perspective of business diversification, from multiple perspectives in a multifaceted market. Specifically, based on segmental financial data, we conduct an empirical analysis of whether increased sales in the transportation business increase the profit margin of the real estate business of a railroad company. The results show that there are two types of sidedness among many businesses. The effects of both positive and negative indirect network effects were found to exist. In addition, verification of the difference-in-differences based on the initiation event of the mutual traffic interconnection demonstrates the indirect network effect in the transportation business to a certain extent, and shows that the effect is not uniform in each business, with some businesses showing strong effects and others showing less visible effects.

A methodology for assessing high-Tech regulation: a legitimacy perspective Reviewed

Language：English Publishing type：Research paper (scientific journal)

This study examines necessary and sufficient conditions in terms of legitimacy with respect to digital platform regulation in the context of today’s development and refinement of sophisticated science and technology. With the increasing oligopoly of platforms, the government has established data portability that can be shifted from a particular platform at any time, creating an environment in which new platform-based businesses can emerge and vigorous competition can take place. In terms of legitimacy, this article considers the following necessary conditions: first, sociological acceptance; second, moral legitimacy; and third, reliance on a foundation that is inherently uncertain but is allowable through expectations of the future. As a sufficient condition, the article also discusses applying social psychology’s elaboration likelihood model, which explains how persuasion is particularly effective in changing people’s attitudes. This approach analyzes ‘resources’ and ‘reflectivity’ in terms of motivating content processing, and ‘expertise’, ‘cognition’, and ‘consequences’ in terms of judging the message based on non-essential peripheral cues. In addition, the point of causality is also examined, and, here, further empirical analysis is needed. The digital platform regulation that has been introduced in Japan has not been clarified in terms of necessity and sufficiency.
