Basing on the fair principle and arbitrage theory, this paper gave out a Rational Consideration Formula in term of market equilibrium. Empirical analysis on 46 experimental firms and 72 firms carrying out recently shows that some consideration schemes were obviously unreasonable. In addition, we explained why the unreasonable consideration schemes have been accepted with high vote by game theory. Finally, using quantitative model, this paper analyzed the relationship between the cost and opportunity for carrying the shareholder structure reform into execution, which shows that nowadays is a very good chance to resolve the shareholder structure problem for the non- circulating shareholders and listed corporations in the term of economy.
