Diversification, vertical integration, and industry analysis: New perspectives and measurement
研究了垂直整合、多元化和行业分析的概念化与正确测量方法，通过分析COMPUSTAT II和TRINET数据库，提出了区分不同阶段垂直整合的潜力，并建议保护研究完整性。
Abstract Vertical integration, diversification, and industry analysis are fundamental topics in strategic management content research. We develop the conceptualization of these issues by exploring their nature as well as their correct measurement. Toward these ends, we conduct an extensive analysis of the COMPUSTAT II data base and the TRINET data base in all three research contexts. In addition to these two data bases, we also evaluate the Census of Manufacturers, S&P's Financial Dynamics , S&P's Industry Surveys and Dun and Bradstreet's Industry Norms and Key Business Ratios , for purposes of industry analysis. Important contributions include our identification of the potential of COMPUSTAT 11 data to distinguish within‐stage forward and backward vertical integration, and between‐stage forward and backward vertical integration, as well as our recommendations for the protection of the integrity of studies based on the COMPUSTA T II and TRINET data bases.
