Analysis of Withholding and Tacit Collusion Behavior of Power Suppliers;
发电商的持留及默契串谋行为分析
2.
With the uniform clearing pricing method and the pay-as-bid pricing method,the power supplier abuses market power by withholding action,but with the EVE pricing method,especially when there is no sufficient electricity,the optimal capacity decision of the power supplier is to su.
指出在统一出清和按报价支付定价机制下,发电商会通过持留行为滥用市场力,而在当量电价下,尤其在缺电情况下,发电商的最优产量决策仍然是申报其最大可用容量,而不是持留发电容量。
3.
Under uniform clearing pricing method,withholding generation capacity is the most common means of abusing market power.
在统一出清电价下,发电厂商常用的行使市场力的手段是持留发电容量。
4) persitance

因此,研发抗结核分枝杆菌持留菌的药物,对缩短抗结核治疗疗程,减少耐药性发生意义重大。
6) physical withholding
物理持留
1.
This article first points out the two market power methods exercised by electricity generation business: physical withholding and economic withholding,then conducts the quantitative analysis to physical withholding using the economic profit maximization principle.
电力市场中市场力的存在不利于电力市场的健康发展,首先指出了发电商行使市场力的两种手段:物理持留和经济持留,并利用经济学利润最大化原理对物理持留进行定量分析,实例表明,物理持留将会使电价上升,发电商利润增大,且需求弹性愈小项有市场力愈大。
补充资料：持气率
分子式：
CAS号：
性质：气相占气液两相混合物的体积分率。空塔线速度是影响持气率的主要因素。在有大量液流循环的高液相流速下，持气率比较重要，当液相空塔流速小于3cm/s时，持气率的影响可忽略不计。
