| Abstract | This study explores the boundary response of domestic firms faced with increased openness to new foreign multinational M&A in an intermediate-input market in a host country. We develop a theoretical framework to study the impact of new foreign multinational M&A on the wholesale price of intermediate inputs as a key market condition in the host country and explore how the intermediate-input prices affect the organizational choice of domestic firms between domestic vertical integration and outsourcing. We find that new foreign multinational M&A raises the intermediate-input prices and facilitates the firms’ choice of domestic vertical integration. |

| Title Alternative | Survival, Creation, and Disappearance of Manufacturing Firms in the First Stage of Regional Revitalization |
| FullText URL | oer_056_3_015_033.pdf |
| Author | Nakamura, Ryohei| |
| Abstract | 地方に位置する多くの自治体においては，従来からある事業所の活性化や新規事業所の誕生に加えて，製造工場の誘致は地域振興にとっていまも重要な政策となっている。今日，高度経済成長期における重厚長大型の産業の誘致とは異なり，地域優位性をできるだけ活用した企業誘致の傾向になっている。雇用創出効果は昔に比べて小さくなっているとはいえ，製造業の多くにおいて，地域の基盤産業としての位置づけは残っている。第1期の地方創生の期間で，どのような地域において，どのような製造工場が消失，撤退や出現，存続しているのかを識別し，それらの要因を分析する。 2014年と2019年の事業所の比較において，付加価値生産性の平均と分布を見ると2014年，2019年ともに存在する事業所の労働生産性が最も高い。次いで高いのが2019年に存在する事業所で，最も低かったのが2014年には存在したが2019年には存在していない事業所であった。またロジット分析の結果から，生産性が高く事業所規模が大きいと消滅しない傾向があり，また都市化の程度が高いと消滅傾向にあることが推定された。他方，発生した製造事業所について，産業別に同業種集積と人口規模で測った都市集積を説明変数とした市町村単位の回帰分析からは正の効果が示された。 |

| Title Alternative | Market Segmentation and Market Reactions to Earnings Announcements: A Quarterly Analysis |
| FullText URL | oer_056_3_001_013.pdf |
| Author | Nakagawa, Toyotaka| Yamanishi, Yuki| Kobayashi, Hiroaki| |
| Abstract | The purpose of this paper is to examine, using quarterly financial data, how the market reaction to earnings announcements in each market segment （prime market segment, standard market segment, and growth market segment） has changed after the revision of market segmentation at the Tokyo Stock Exchange. For the research design, the abnormal volume and residual returns for the 12 quarters around April 1, 2022, when the market segmentation was changed, were calculated using the analysis method of Beaver et al. ［2020］. The results of the analysis suggest that volume is significantly affected by changes in market segmentation. In addition, for the group of stocks in the growth market, there appears to have been some change in the trend of stock price fluctuations after the market segmentation revision. |

| Title Alternative | Reproducing Self-organizing Agglomeration using Agent-based Model: ICT Establishments in Tokyo’s Special Wards |
| FullText URL | oer_056_2_041_071.pdf |

| Abstract | As a preliminary step to conducting a self-organizing simulation of the agglomeration and dispersion of the information and communications industry, we quantify the spatial agglomeration of the information and communications industry in Japan’s major cities. Using the town and district data from the Economic Census for Economic Activity, we attempted a spatial analysis of the information and communications industry in the Tokyo Special Wards as well as in Sapporo, Sendai, Hiroshima, and Fukuoka, which have regional central functions. As a result of detecting spatial autocorrelation in small areas within each city, hotspots indicating the agglomeration of information and communications industry offi ces were found in the city center of each city. At the same time, we were able to confi rm the impact of agglomeration economies, which are the premise of the self-organizing model, and confi rmed that the information and communications industry is an industry suitable for simulation of the self-organizing model. Krugman（1996）was the fi rst to model the self-organizing model in cities and clarifi ed the emergence principle of peripheral cities, but this was limited to numerical simulations. Later, Kumar et al.（2007）used actual data to show that Krugman’s self-organizing model could be applied to predict corporate agglomeration and dispersion. In this paper, we use an agent-based model to examine whether a self-organizing model is also effective in reproducing and predicting the concentration and dispersion of the information and communications industry in Japanese cities. |

| Author | Mimura, Satoshi| Tokoo, Akane| |
| Abstract | 岡山大学の公認学生サークルのなかで地方創生活動を展開しているサークルに「まちづくり研究会」がある。岡山大学学生サークル「まちづくり研究会」は，2014年に活動を開始，その活動の目的は，過疎化人口減少の問題を抱える瀬戸内市邑久町虫明（おくちょうむしあけ）の裳掛（もかけ）地区をフィールドとした学生と地域住民による地方創生の協働活動であり，通称『瀬戸内市裳掛地区再生プロジェクト』と呼ばれている。 この10年間，学生たちは先輩たちから後輩たちに実践活動をリレーしながら様々な活動を展開してきた。その主眼が，生徒数の減る裳掛小学校の子どもたちの支援活動を続けることで，生徒数の減少に歯止めをかけることである。そのための具体的な方策として，「学生による情報発信」，「耕作放棄地対策への参加」，「空き家の再生支援による拠点づくり」，「移住定住促進支援」，「地域催事への企画・運営支援」，「子どもたちの見守り」などの活動を実践しながら地域を元気にする応援を継続してきた。なお，掲載写真の使用許可は，活動の都度，地域の皆様（保護者を含む）や学生たちに確認・了解を得ている。 本論では，この学生たちの活動の成果を紹介しながら，学生たちの学びと地域への貢献という互恵性の視座に立ち「学生による地域創生活動の実践事例研究」として報告する。 |

| Title Alternative | Why Is Intermediate Organization Necessary? |
| FullText URL | oer_056_2_001_016.pdf |
| Author | Fujii, Daiji| Oshima, Tamako| |
| Abstract | This paper challenges a fundamental question, ‘Why is an intermediate organization necessary?’ Due to transaction costs and market failures on the one hand and the limitations of organizational control mechanisms on the other hand, many‘ intermediate organizations’ are observed in the real world. How can we tackle to explain the governance mechanism considered to be‘ intermediate?’ If we are to discuss such socioeconomic orders, this paper assumes that we should not be able to link micro-level explanations and macro-level ones concerning the third mode of governance mechanisms all at once. We need to stick to the meso-level at fi rst. The theoretical elaboration since Ouchi’s（1980） discussion of clan-type governance and cumulative empirical research on industrial agglomerations have allowed us to construct a more sophisticated theory called community capital. In effective communities, members are ‘embedded as insiders’ who serve the purpose of the community, share experiences of failures and successes, and find and deepen their common identity. This limited membership is bound by‘ mutual trust to rely on each other’ for‘ distribution of short-term risks.’ In contrast to social norms that need to be abstract enough to be widely shared, the communal norms that are concrete enough to allow the members to understand without hesitation how they should behave in localized contexts are cumulatively cultivated along socializing process. Among the norms, sense of mutual obligation to incur intermittent costs for the whole community is a crucial norm for the sustainable development of the community. However, as a practical matter, membership control, mutual trust and short-term risk allocation may serve the communities in the short run, but they do not guarantee long-term accumulation of shared capital. As a result, the limits of community capital may need to be discussed once again, especially today when market liquidity is increasing, and its failures tend to become more apparent in a variety of areas. |

| Title Alternative | Firm Entry and Exit in the First Stage of Regional Vitalization: Revolving Door Economy or Creative Destruction |
| FullText URL | oer_056_1_001_028.pdf |
| Author | Nakamura, Ryohei| |
| Abstract | The growth of the regional economy needs an economic metabolism in which high-productivity firms newly enter the market, while low-productivity firms exit the market, resulting in a shift in labor and other production factors. A“ revolving door” economy is an economy in which firms that enter the market have a short existence period, withdraw and enter the market repeatedly, and new entrants do not contribute to productivity improvement. This means that if new entrants are not sufficiently innovative compared to incumbents, even if the rate of entry into business rises, they will simply be replaced by firms whose productivity level has not changed much, and this will not lead to job creation or improving productivity. A contrasting concept is the replacement of firms by Schumpeter's “creative destruction.” The high level of technology and productivity of new firms entering the market drives inefficient incumbents out of the market. Looking at the statistics, there is a tendency for both large cities to have higher business entry and exit rates, but the difference between the entry and exit rates is greater in metropolitan areas. Although it depends on the regional characteristics, location competitiveness is generally higher in metropolitan areas, and there is a tendency for the turnover rate to be high or the survival period to be short. Before and after regional revitalization, we will examine whether or not there is a departure from the revolving door economy by industry and region, using economic census and TSR （Tokyo Shoko Research） data. |
