The character of core stakeholders corporate governance is that core stakeholder, manager, employee are the ownership of material capital and human capital of the firm. They share the firm surplus demand right and control right. On the way of benefit distribution, the core stakeholders' corporate governance can avoid to make parasitic relation and have partiality for benefit relation, which can form mutually beneficial and alternate relation. So this paper introduces intergrowth degree and intergrowth coefficient for describing the stakeholders corporate governance.
