摘要
天然气管输是连接天然气“上下游”的重要环节,科学合理的天然气管输定价对天然气市场发展具有重要意义。国家管网公司的成立在进一步推进“管网独立”的同时,也对传统的管输定价及其机制提出了挑战。基于政府与管输企业在天然气市场的双层决策机制,建立了上层政府以社会效益最大化为目标和下层管输企业以利润最大化为目标的双层规划模型,通过算例模拟,比较了在传统的与“两部制”的管输定价机制下,天然气管输定价及其对社会效益的影响。结果表明:在“两部制”定价机制下,管输量显著增长,管网利用效率显著提高,管输企业承担的总成本降低,总收益增加;两部制定价机制促进了天然气市场交易,极大提升了社会效益。并且,为构建合理的管输定价体系,提出相关政策建议。
The transmission of natural gas pipeline serves as an important link connecti ng the “upstream” and “downstream” of natural gas. And scientific and reasonable pricing of natural gas pipeline transportation is of great significance to the development of natural gas market. The establishment of PipeChina advances the “independence of the pipeline and network”. Also, it raised challenge towards traditional pricing and mechanism of pipeline transmission.Based on the dual decision-making mechanism featuring government and pipeline transmission enterprises in the market, a two-level programming model has been established in which the upper-level government aims at maximizing social benefits and the lower-level pipeline transmission enterprises target at maximizing profits. By way of simulation,this paper compares the pricing of natural gas pipeline transmission and its influence on social benefits under the traditional and “two-part system” pricing mechanism. According to the result, based on the “two-part system” pricing mechanism, the pipeline transmission volume increases significantly, the pipeline network utilization efficiency increases significantly, the total cost borne by the pipeline transmission enterprises decreases, and the total revenue rises;such pricing mechanism facilitates the transaction in the natural gas market and gre atly improves social benefits.Besides, relevant policy suggestions have been proposed herein in order to build reasonable pipeline transmission pricing system.
