中文摘要：

社交新时代的到来使企业内正式及非正式网络互动问题愈发突出。主流理论往往将企业内正式及非正式因素割裂开来讨论；而少数尝试分析组织内正式和非正式网络互动的研究还停留在概念界定不完整、研究关系静态的阶段，难以反映正式和非正式网络互动影响企业的全貌。CAS理论提供了崭新的思路。在系统分析以往理论研究的基础上，基于CAS视角并结合社会网络分析了企业正式及非正式网络互动适应环境的现象、机理、权变情境等问题，构建了企业通过正式和非正式网络互动适应环境相关问题的理论框架，希望从根本上推动主流理论关注组织内正式及非正式因素整合，弥补现有研究存在不完整和静态的不足，并为实践界设计正式和非正式网络适应环境提供指导。

英文摘要：

With the advent of the new social era, the interplays between formal and informal elements of organiza- tions have become more important. Mainstream theory often separates to discuss formal and informal factors of or- ganizations. Furthermore, a few studies of the interplay between formal and informal networks of organizations are still stuck in the concept of incomplete definition and the static level of research relationships, which is diffi- cult to reflect the overall picture of interplays between formal and informal networks of organizations. CAS theo- ry provides us with a new way of thinking. Therefore, the study is ready to analyze related issues which enterpri- ses adapt to the environment with the help of interplays between formal and informal networks of organizations by using mixed research methods based on CAS perspective. Firstly, we will prepare a complete definition of the types of interplay between formal and informal networks of organizations by learning from the concept of ＇legal system＇ and ＇shadow system＇. Secondly, we will analyze the impact of interplays between formal and informal net- works of organizations on organizational adaptation according to the concept of ＇order＇, ＇chaos＇ and ＇disorder＇. Final- ly, we will explore the mechanism and contingency conditions of the above-mentioned relationships based on the theory of ＇edge of chaos＇, ＇creative space＇, ＇the match between the complexity of system and the complexity of en- vironment＇. We hope to promote the study of the integration of formal and informal factors and attract more inte- rests of the mainstream theories, and fill fundamentally the gap of the existing research on the concept of incom- plete definition and the static level of research relationships, and provide guidance of the design of formal and in- formal networks to adapt to the environment for management practices.
