The stability and predictability of the institution let it become the foundation of social order in the relentless pursuit of the process in the efficiency and effectiveness in western nations，institionalization becomes a certain result of its organization and management，and has been internalized among the whole social and cultural backgrounds.China has been in the critical period of transforming from“economic construction”to“institutional construction”；unfortunately，currently the management of many universities’libraries have still existed in the state of lacking institutionalization and the institutionalizing process of organization management is relatively backward.With the rapid changes of technology，structure and environment，university library needs to cope with these changes efficiently in terms of institution.In other words，whether it can coexist with external resources of exchange depends on the effectiveness of its management system.

Based on a variety of relative research studies and cases both from home and abroad，this study defined a theoretical boundary of the effectiveness of management system of university library.Additionally，it also constructed theoretical model and recognized critical dimension of its effectiveness；meanwhile，the present study developed the measurement scale for the management system effectiveness of university library.

The main conclusions of this study were.

1.The basic concept of the effectiveness of university library’s management system.Based on the literature review，this study Preliminary proposed the basic concept，that is“It is a symbolic criteria established by university library，under the joint influence of consistent framework and institutional mechanisms，it can promote the institutional individual to meet institutional goals，as well as to improve the ability of adjusting the institutional texts dynamically.”

2.The theoretical model of the management system effectiveness of university library.This study constructed the theoretical model through a grounded theory research on three university libraries，based on institutional text，institutional environment，institutional mechanism and institutional individual，which referred to the formation of the effectiveness in terms of the establishment，implementation and adjustment of institution in the process of management institution of university library.

3.Four dimensions of the management system effectiveness of university library.197 analytic units were analyzed in order to recognize the criticaldimensions of the effectiveness：operability，structure，legitimacy and consistency.Besides，the critical elements model of the management system effectiveness of university library was constructed.

4.The panoramic concept of the management system effectiveness of university library.The current study traced theories of management system of university library，defined its theoretical boundary，constructed its theoretical model and recognized related four features.Additionally，it developed the measurement scale for the effectiveness which tested the theoretical model and conceptual structure in depth.In conclusion，in terms of the panoramic concept，the management system effectiveness of university library refers to a symbolic criteria established by university library according to its internal organization and external environment，which has operability，equilibrium，compatibility and constraint.Under the joint influence of framework consistency and institutional mechanism，the effectiveness could impel the individual to meet the institutional goals，considering the quality of its own ability level and emotional value judgment.

Based on theoretical analysis and empirical research，Innovations of this research as follows.

1.Establish a position for the research on the management system effectiveness of university library.Related studies belong to the categories under the theoretical framework of organization，institution，management，and library science.And the research findings would enrich and deepen related studies.

2.Constructing the panoramic concept of the management system effectiveness of university library.The current study defined theoretical boundary of the management system effectiveness of university library，constructed its theoretical model，and recognized four features，which established the theoretical basis for the relevant research study，and provided the research direction.

3.Developing MIE assessment scale for the management system effectiveness of university library.In terms of research studies on the effectiveness，the assessment scale based on the theoretical model with logical association is critical for research paradigm transforming from qualitative to quantitative.Besides，it was also an effective step to test the management system effectiveness of university library.
