| 摘 要： | 世界天然气流动格局演化及其资源效应对科学制定中国天然气发展战略具有重要指导意义。本文采用标准差椭圆分析世界天然气输流节点和汇流节点的资源流动格局及其演化特征,进而揭示格局演化的资源效应。结果表明：①世界天然气供需格局呈现东移发展趋势。管道天然气输流节点东西方向性发展逐步增强,节点分布重心呈现东移趋势;液化天然气输流节点分布在东西和南北两个方向都呈现离散发展趋势,重心移动具有显著的西北-东南阶段性迁移规律;②管道天然气汇流节点格局显著东移,汇流分布在东西向的方向性持续加强;液化天然气汇流节点格局亦整体东移,空间向心集中发展;③世界天然气高流动密度地区主要集中在亚欧大陆及其沿海国家,流动网络呈现出关键节点主导特征;管道天然气以东西流向为主,液化天然气流向较为复杂;④随着世界天然气流动节点格局的不断演化,全球天然气竞争格局、交流关系以及资源治理体系将发生一系列变革。基于研究分析,提出中国应加快页岩气产业革命,持续推进天然气海外供应多元化,引领国际天然气通道规划,加强亚洲天然气贸易枢纽和金融中心建设以及提升全球天然气治理地位等发展建议。 |

| Abstract: | Research on the evolution of the global pattern of natural gas flow nodes and the resource effect have important guiding significance for the scientific formulation of China’s natural gas development strategy. This study used the standard deviation ellipse (SDE) method to analyze the spatial pattern characteristics of export and import nodes, and then reveal the resource effect of pattern change. The following conclusions are drawn from the research: (1) The supply and demand nodes of natural gas in the world are moving eastward. The development of pipeline natural gas (PNG) export nodes in the east-west direction is gradually enhanced, and the nodes distribution gravity center shows a trend of eastward movement; the liquefied natural gas (LNG) export nodes distribution in the east-west and north-south directions shows a trend of dispersion, and the gravity center shows a significant northwest-southeast movement. (2) The PNG import nodes show a significant eastward movement, and the east-west direction of import nodes distribution has been continuously strengthened; the LNG import nodes have moved eastward as a whole and are centralized. (3) The high flow density areas of natural gas in the world are mainly concentrated in the Eurasian continent and its coastal countries, and the flow network shows the characteristics of key node control. The PNG mainly flows in the east-west direction, and the LNG flow direction is more complex. (4) With the continuous change of the spatial pattern of global natural gas flow nodes, a series of changes will take place in natural gas competition, communication relationships, and resource governance systems. China should speed up the shale gas industry revolution, continue to promote the diversification of overseas natural gas supply, contribute to the planning of international natural gas channels, strengthen the construction of Asia’s natural gas trade hubs and financial centers, and enhance China’s position in global natural gas governance. |
