企业与环境的互动关系是组织和战略管理研究的核心主题。我们认为，其一，有关环境影响企业战略的文献多关注产业或企业内部因素的作用，而忽视了介于产业和企业之间体现组织间关系的集群影响；其二，有关企业行为对环境的反作用研究中，现有制度变革文献忽略了组织构建环境的微观过程和条件。在我国，丰富多样的企业集群为考察环境与企业的互动过程提供了适宜的情境和研究层面。因此，本研究以乡镇企业集群为对象，整合制度理论和社会网络理论，运用问卷调查和档案数据等方法，探究集群制度与企业间网络特征对集群内企业战略的影响机制；采取过程研究方法，运用案例研究和深度访谈等手段，考察企业行为构建集群制度环境的反作用过程和条件，试图描绘出完整的制度环境、企业间网络和企业战略间的互动机制。本研究不仅对企业选择并适应集群、政府优化集群管理具有指导意义，而且为我国乡镇企业集群的发展和变迁提供了基于制度和社会结构视角的解释。

The interplay of firm and environment is the core theme in organizational and strategic management study. When examining the effect of environment's influence on firm strategy, extant literatures overemphasize the impact of macro level industrial or the intra-firm factors, ignoring that of firm's most proximate external environment- - cluster. When investigating the active role of organization on environment, institutional change studies fail to examine the condition under which individual organizations could shape environment and the micro-process of this change. The township enterprise clusters in China provide a perfect scenario to examine the interaction of organization and environment. Therefore, in this study, we would like to explore how township cluster institution and inter-firm network characteristics impact firm strategy by integrating institutional theory and social network theory and using questionnaire and archival data. Moreover, we will employ process method and conduct case study or survey to investigate when and how firm behaviors could shape cluster institution environment. In this way, we would capture the interactive mechanism of institutional environment, firm network and firm strategy. This study serves an important guidance for firms to choose and further adapt to cluster, for government to improve cluster management. It also provides an explanation for development and evolvement of township clusters from the perspective of institutional theory and network theory.
