On the basis of the perspective of co-construction，co-governance and sharing，this paper analyzes the influence of government guiding social capital to empower comprehensive land consolidation.An evolutionary game model of government and social capital is established through the theoretical derivation method.Based on the survey data of comprehensive land consolidation projects in Hubei province，the evolution trend and behavior strategy of government and social capital are dynamically simulated.The research results show that：The concept of co-construction，co-governance and sharing points out the influencing factors and logic of the behavior of government guiding social capital to empower comprehensive land consolidation from the dimensions of subject，tool，and value.The concept of co-construction，co-governance and sharing expands the game space between the government，the initial intention，government subsidies，government penalties，and incremental costs are key factors that affect the behavior strategy of game players.The changes of key factors can have different types and degrees of influence on the behavioral strategies of social capital.In conclusion，the government can effectively guide social capital to empower the comprehensive land consolidation by implementing incentive policies，integrating departmental resources，implementing reward and punishment measures.It will promote the transformation of land consolidation mode from strong government dominance to co-construction，co-governance and sharing among multiple stakeholders.
