Abstract: Under the background that the Chinese economy has been stepping into the new normal, the contradiction and conflict in the field of labor relations have become more and more serious. Therefore, it is necessary to play the role of the labor relations adjustment mechanism, including collective bargaining on wage. This paper argues that the implementation of collective bargaining in the practice is not satisfactory and the key reason is the role of the state is not in place. Consequently, the state needs to define its relations with labor and capital, and carry out effective coordination between two sides in collective bargaining on wage. The state should not play the leading role in the collective bargaining on wage, but should be the maker of the rules, the coordinator and referee of the contradiction between labor and capital, and the defender of public interest. In the face of the overall situation of "strong capital and weak labor", the state should mainly through legislation support for the labor and regularize and restrict the captital, in order to achieve the proper balance between labor and capital, so as to promote the optimization of the collective bargaining system on wage and the effective governance of labor relations, and thus provide a stable social environment for Chinese economic transformation and upgrading and stepping into the new normal.
