本文运用技术，以区域经济学、城市地理学等相关理论为指导，探讨城市酒店空间分布规律。指出酒店的空间分布与城市商业布局密切相关，多位于城市经济实力较强的城区，集聚于旅游资源丰富的地区，集聚于交通干道和次干道附近基本符合土地总体价格的阶梯分布，与城市发展规划相一致。

从世界油气资源的空间结构入手，根据其与社会经济空间结构的耦合关系，提出世界油气工业三大空间结构模式，即协同发展（就近供应）模式、通道发展模式和点轴发展模式，以期能为我国油气工业的发展提供有益的思路和借鉴。

目前新能源的发展普遍存在着数量和质量两大问题，世界许多国家均以制定新能源政策为手段，以促进新能源产业的健康发展。文章对世界主要国家新能源政策进行了系统梳理，探讨世界新能源政策的框架基础与形成机制。其框架基础包括战略规划、法律法规和管理体系3个方面，在形成机制上，表现为“关注外部性”和“持续自生”两大原则及“推动”和“引导”一组合力。并从新能源产业的“生产前—生产—市场—消费”四大阶段具体阐述了世界新能源政策框架，力图为我国新能源产业的持续健康发展提供有益的思路与借鉴。

Crude oil flow is a sort of oil spatial movement, and in China, it is large scale and covers wide area with extensive social-economic effects. This paper analyses the spatial structure of crude oil flow in China, the characters of its flow field and the layout of its flow track. The results show that oil flow in China has a spatial characteristic of centralized output and decentralized input; its spatial structure is composed of Source System in the shape of right-angled triangle, Confluence System in the shape of right-angled trapezium and Multiplex System in the shape of obtuse-angled triangle, which are mutually nested, and on a whole, the presence of Multiplex System balances and optimizes the flow layout; oil flow field in China can be divided into four parts, i.e. the North, North-west, East and South Field, two or three of which overlap with each other, extending the oil flow and making the flow more flexible and maneuverable; oil flow track is a multi-objective decision-making route and in the decision-making process oil transportation cost is one of the essential factors, in China, oil flow track falls into the Northeast, North, East, Northwest and South five cluster regions, which connect with each other, and series–parallel connection between various kinds of transportation channels is widely seen in them, reinforcing the supply security of crude oil.
