“Suggestion” in the fifth plenary session of the 18th central committee is proposed that “the social governance of the whole people co-construction and sharing” reflects our party’s great changes in the idea of social governance. The “Co-construction and sharing” embodies that people are the creators of the reform and development achievements. The “Co-construction and sharing” is also the enjoyment’s development ideas of the reform and development achievements. The “sharing” can only be achieved through the “co-construction”. If the co-construction is the common responsibility of all members in the society，sharing development achievements is the right which people should have. The “sharing” needs to be achieved through the “co-construction”. The key of which is to deal with the dialectical relationship between sharing and development. The relationship tries to avoid the “development of non - sharing”，“sharing of non - development” and “no development and no sharing”. The implementation of “sharing development” needs to combine the current social governance innovation，which is realizing the goals of “sharing development”. The goals contain that according to the level of economic development，guarantee the people to share the achievements of reform and development；to realize the effective supply of public goods and social services，guarantee the social fairness and justice；to focus on the people’s developmental livelihood construction，the “whole people co-construction” promotes the “whole people sharing”；to break the development bottleneck，complete the short board of sharing development.
