In the Market Equilibrium with Stocks, the necessity for existence of stocks stems from the contradictions of the continuity and discontinuity,the elasticity and inelasticity between supply and demand; stocks's role in a Market Equilibrium with Stocks formation mechanism is largely embodied by a cumulative difference of supply and demand, rather than a simple short-term supply and demand residual error.

在有库存市场均衡中，库存存在的必然性源自于供给与需求在连续性与非连续性、富于弹性与缺乏弹性之间的矛盾；库存在有库存市场均衡形成机制中的作用，更多的表现为一个累积效应下的供求差额，而不是简单的短期供求残差。
