随着世界能源供需格局的变化,中国与加拿大天然气方面的合作逐步加强。本文将经济学理论与突变理论相结合,构建出价格尖点突变模型用于加拿大2002-2011十年间天然气价格的突变研究。结果表明加拿大天然气价格十年间变动不大,说明加拿大政府对国内天然气价格的调控很有效,中加关于天然气的合作具有保障。最后,给出中国企业投资加拿大天然气项目的建议。
As the world’s energy supply and demand pattern changes, China and Canada’s natural gas cooperation has been gradually strengthened. This paper combines the theory of economics and catastrophe theory to construct a cusp catastrophe model to study the abrupt change of natural gas prices in Canada during the decade of 2002-2011. The result shows that the price of natural gas in Canada has not changed much in the past 10 years. This shows that the Canadian government is very effective in controlling the price of natural gas in China and that Sino-Canadian cooperation in natural gas is guaranteed. Finally, the suggestions of Chinese enterprises to invest in Canadian natural gas projects are given.
