制度偏好差异与电力产业规制放松的困境--"厂网分开"引发的深层思考

本文利用“芝加哥”学派利益集团理论的基本假设，对我国电力产业内部人势力的形成、强化及其行为对市场交易的扭曲进行了详尽的分析，从而为当前电力产业规制困境的发生提出了一个基于制度偏好和企业行为的解释。结果表明，在缺乏有效规制的背景下．对自然垄断产业实施等同于一般产业的“放权让利”武改革，为利益集团的成长提供了制度条件和资金支持。由于管制权力分散在诸多的“条块”之间。“厂网分开”后也没有建立权威性的专业机构．不同利益取向的参与者之间的博弈使电力产业的规制放松陷入困境。     

THE BENEFITS OF STRATEGIC HOMOGENEITY AND STRATEGIC HETEROGENEITY: THEORETICAL AND EMPIRICAL EVIDENCE RESOLVING PAST DIFFERENCES

Past research on the relationship between strategic variety and industry profitability has argued for either high homogeneity or high heterogeneity. In this paper, we review the literature on strategic variety and use it to develop hypotheses suggesting that the relationship between strategic variety and average industry profits is curvilinear. Based on our analysis of 61 industries, we find empirical support for our hypotheses, suggesting that very high levels of heterogeneity or homogeneity are more likely associated with industry profitability, while the industries in our sample displaying moderate levels of strategic variety are most likely to suffer from widespread financial losses.     

Playing dirty or building capability? Corruption and HR training as competitive actions to threats from informal and foreign firm rivals

Research summary : We examine why a firm takes specific competitive action in nonmarket and resource‐market spaces, particularly when it perceives threats from informal and foreign competitor groups, respectively. We address this question by combining insights from competitive rivalry, strategic groups, and nonmarket strategy literatures in an emerging economy context. Specifically, we theorize how threats from informal and foreign rival firms in an emerging market influence a firm's engagement in corruption activities and its investments in HR training, respectively. We also argue that the likelihoods of such focal firm actions against competitor group threats differ, contingent on the focal firm's market and resource profiles. Results from the empirical analyses, with survey data from the Indian IT industry, provide broad support to our hypotheses. Managerial summary : Based on a World Bank dataset on the Indian IT industry, this study finds that corruption and HR training are pursued by firms in emerging economies as mindful strategies against specific types of rivals—informal and foreign firm rivals, respectively, and are not pursued simply as culturally‐based practices. Multinational companies may need to understand that domestic firms in emerging countries will engage in corruption strategically to reduce their costs and time to market of their products/services. Therefore, multinational firms may need to devise suitable strategies other than corruption to reduce their costs and time to market if they wish to compete with firms in emerging economies for customers who don't care about ethical issues and will buy a cheaper product/service that is delivered quickly.

Does group membership matter? Evidence from the Japanese steel industry

In this study we address criticism that performance differences among strategic groups found in past research may be spurious and attributable to firm effects. The Japanese steel industry provides the setting for the study. Our analysis is based on data from the carbon steel sector of the Japanese steel industry for the periods 1980–87 and 1988–93. A one-way ANOVA indicated that the average performance of firms in the two technology-based groups in this industry—the integrated mills and the minimills—were significantly different during the two periods. Subsequently, we performed a regression analysis to examine the residual group effect after controlling for both environment and firm-specific effects. We found that even after controlling for both environment and firm-specific effects group membership was significantly associated with firm performance. Copyright © 2001 John Wiley & Sons, Ltd.

Measuring strategy coherence through patterns of strategic choices

Strategies at different levels need to be coherent to ensure competitive advantage (Hofer and Schendel, 1978). Strategy coherence is the consistency of strategic choices across business and functional levels of strategy. In this paper we focus on strategy coherence. Using patterns of strategy, we develop a measure of the extent of strategy coherence. The relationship between coherence and performance is used to validate the measure. We illustrate the application of the measurement and validation process, in the context of acute care hospitals. The results indicate that our measure of coherence is monotonically related to performance. We also find performance differences between more and less coherent hospitals on the industry specific performance indicator of occupancy. Implications for theory and practice are highlighted.     

Using information‐processing theory to understand planning/performance relationships in the context of strategy

This study reveals the importance of viewing planning processes within the context of strategic orientation. Information‐processing theory is used to examine the differences in planning processes given variable strategy content in the banking industry. Findings suggest that banks implementing different strategies require their planning systems to focus on different kinds and amounts of information. Moreover, the relationship between planning and bank performance is clarified when information requirements of a specific strategy are considered. It appears the strategy moderates the relationship between planning and performance. Copyright © 1999 John Wiley & Sons, Ltd.

Convergence across alternative methods for forming strategic groups

We studied the convergence of three different methods for identifying group structure (strategic groups) in a single competitive environment. Using a version of the MTMM matrix, we tested the convergent validity of the concept of strategic groups in a mature, geographically delimited competitive environment. We find significant evidence of convergence between competitive structures identified using archival and perceptual data as well as those identified using archival measures of strategy and direct measures of competitors. There is limited evidence of convergence between competitive structures identified from perceptual and direct measures. Taken as a whole, these results are consistent with the emerging theory of strategic groups. We conclude that strategic groups are a theoretical construct and not a methodological artifact, as is suggested by some authors. © 1997 John Wiley & Sons, Ltd.     

Competitive positioning within and across a strategic group structure: the performance of core,secondary, and solitary firms

Drawing from economic and cognitive theories, researchers have argued that firms within an industry tend to cluster together, following similar strategies. Their positioning in strategic groups, in turn, is argued to influence firm actions and firm performance. We extend this research to examine performance implications of competitive positioning not just among but also within groups. We find that performance differences within groups are significantly larger than across groups, suggesting that some firms within groups develop better resource or competitive positions. We also find that secondary firms within a group outperform both core firms within the group and solitary firms, the latter being those not belonging to any multifirm strategic group. This suggests that secondary firms may be able to effectively balance the benefits of strategic distinctiveness with institutional pressures for similarity. We conclude that the primary implication of strategic groups does not relate to the ability of firms to create stable, advantageous market segments through collusion. Instead, strategic groups represent a range of viable strategic positions firms may stake out and use as reference points. Moreover, our results concerning secondary firms indicate that firm positioning within a group structure can have performance implications. Copyright © 2002 John Wiley & Sons, Ltd.
