【摘要】：创新煤炭交易机制为处理好政府与煤炭市场的关系、解决煤炭市场稳定问题提供新思路。传统的交易机制如挂牌交易、竞价交易、招标交易都具有单向选择性、信息不对称、竞争不充分和交易关系不稳定等缺点。双边匹配理论为解决煤炭供需企业稳定匹配问题提供了理论基础。本文的煤炭供需企业稳定匹配交易模型是对双边匹配模型的进一步拓展。利用带交易量的延迟接受算法,可以求得煤炭供需企业稳定匹配结果。该算法具有可操作性,即煤炭供需双方可以通过调整偏好和供需量,达成预先约定的匹配交易。算法下得到的匹配结果为煤炭需求企业最优的成对稳定匹配结果,更好地保护了消费一侧的利益。算法具有较为广泛的适用性,是对婚姻匹配模型、大学生入学模型、企业员工匹配模型下延迟接受算法的一般化,可以求取其中任意一种模型的成对稳定匹配结果。煤炭供需企业稳定匹配交易机制也是对竞价交易和招标交易的融合、一般化,可以通过参数设定转化为竞价交易和招标交易机制。在煤炭供需企业稳定匹配交易机制下,匹配交易成对稳定具有一定的交易量弹性范围,单个供应方供应量的小幅度增加或者单个需求方需求量的小幅度减少不会改变算法的匹配结果。更重要的是,如果供应方能够准确响应需求方的需求变化,稳定的匹配关系也不会因为供需量变化而改变。带交易量的延迟接受算法具有较高的算法效率,能在较短的时间内得出结果,能够适应大量用户的匹配交易运算。挂牌交易的匹配结果可能存在多个阻碍匹配对,造成交易关系的不稳定。与挂牌交易不同的是,煤炭供需企业稳定匹配交易机制能够避免阻碍匹配双对的出现,使得供需企业之间形成相对稳固的交易关系,从而也能便于煤炭企业更加准确的响应市场的需求,应对市场的变化。
[Abstract]:The innovation of coal trading mechanism provides a new way to deal with the relationship between government and coal market and to solve the problem of coal market stability. The traditional trading mechanism, such as listing, bidding and bidding, has the disadvantages of one-way selectivity, asymmetric information, inadequate competition and unstable trading relationship. Bilateral matching theory provides a theoretical basis for solving the problem of stable matching between coal supply and demand enterprises. The stable matching transaction model of coal supply and demand enterprises in this paper is a further expansion of bilateral matching model. The stable matching results of coal supply and demand enterprises can be obtained by using the delay acceptance algorithm with trading volume. The algorithm is operable, that is, both sides of coal supply and demand can reach a pre-agreed matching transaction by adjusting their preferences and quantity of supply and demand. The matching result under the algorithm is the optimal pairwise and stable matching result of the coal demand enterprise, which better protects the interests of the consumption side. The algorithm has more extensive applicability, which is the generalization of delay acceptance algorithm under marriage matching model, college entrance model and enterprise employee matching model, which can obtain the pairwise and stable matching results of any one of the models. The stable matching transaction mechanism of coal supply and demand enterprises is also the integration of bidding and bidding transactions, which can be transformed into bidding and bidding by setting parameters. Under the stable matching trading mechanism of coal supply and demand enterprises, matching transactions have a certain range of trading volume elasticity. A small increase in the supply of a single supplier or a small reduction in the demand for a single demand-side will not change the matching result of the algorithm. More importantly, if the supply side can accurately respond to the demand changes on the demand side, the stable matching relationship will not change with the change of the supply and demand quantity. The delay acceptance algorithm with transaction volume has high efficiency and can get results in a short time. It can adapt to the matching transaction operation of a large number of users. The matching result of the listed transaction may have several blocking matching pairs, resulting in the instability of the trading relationship. Different from listed trading, the stable matching transaction mechanism of coal supply and demand enterprises can avoid obstructing the occurrence of matching double pairs, and make a relatively stable transaction relationship between supply and demand enterprises. Thus, it is convenient for coal enterprises to respond more accurately to market demand and market changes.
