中国多气源天然气区域市场特点与定价原则

Market characteristics and pricing principles of Chinese natural gas regional market with multiple gas sources

多种气源混合输送将是中国天然气区域市场的发展趋势,如何定价将成为未来市场的焦点。中国区域天然气市场具有气源多样化、客户类别化、供应灵活化、调度一体化的特点,也存在不同气体质量的互换性、混合气的区域标准等关键问题。在综合分析的基础上,建立了多气源混输的定价模型,并提出了区域市场的定价原则:①统一以热值为计价单位,以混合比例确定基本价格;②制造成本以成本加成为主,合理确定不同区域交付价格。

The mixed transportation with multiple gas sources is the developing trend for natural gas regional market in present China,thus the issue of pricing has become the focus of future gas market.In the future regional natural gas market,the integrated regulation and distribution will guarantee the classified end users to obtain all kinds of gas sources through flexible supply ways;while the key problems will have to be encountered such as the interchangeability of different gas quality and the regional criteria and standards of the mixed gases.On the basis of the analysis of the above problems,a pricing model is set up for the mixed transportation with multiple gas sources,and the gas heat value is recommended to be the pricing foundation by use of the cost-plus pricing system as the principle.
