“Three Social Co-ordinations” is a new measure of social governance innovation in the new era，bring new support to community development. This new thing is facing some special challenges in the process of embedding the original community governance，especially in the development of the Western Region. Through the investigation of the pilot community of “Three Social Co-ordinations” in Gansu province，this study found the following challenges：The development space of professional social workers under the leadership of administration is insufficient；The three associations are “linked” without moving，which is difficult to effectively coordinate and operate efficiently；Community social organizations are stunted and cannot effectively play their role in community governance；The problems of shallow involvement in social work and formalization of community participation are prominent. At the same time，the development of social workers’ talents lags behind the people’s demand for social work services for a long time，which is also a bottleneck restricting the further development of the three social cooperatives. Social workers，social organizations，etc. are easily absorbed by the original administrative system，which further expands the original administrative system，making the “Three Social Co-ordinations” risk of “involvement”. This article puts forward the corresponding policy suggestions based on the practical environment generated by the problem，with a view to helping the practical exploration to achieve a good operation.
