中国石化原油多元化国际投资战略研究

2010年我国进口原油2．39亿吨,原油对外依存度已经超过55％。截至2010年,三大石油公司的海外业务已遍及全球50多个国家和地区。中国石化海外原油产量从2008年的901万吨增长到2009年的1700万吨。在当前“走出去”的大环境下,为保证我国的能源安全,中国石化也在积极寻求海外油源多元化投资。中国石化海外油源投资应主要关注石油储量和产量排名前三十名的国家,包括亚太国家7个,非洲国家6个,中东国家7个,欧洲和西半球国家10个。根据政治、储量、技术、经济和环保五类风险的分析结果,优选地区排序依次为中东、非洲、南美、亚太和中亚。在海外油源国投资时,针对政治、经济、管理、技术和自然环境风险,应采取与当地国际石油公司加强合作、认真分析当地法律政策、进行资产管理分散风险、加大科技研发投入、加强安全培训等方法。中国石化在未来油源国际化投资的发展战略中,应加大上游投入,发挥自身优势与国际石油公司合作共赢,并且在国际上游投资难度不断加大的情况下,大胆采取与境外公司并购的方式获取油源。

International Freight Forwarding Services Network in the Yangtze River Delta, 2005–2015: Patterns and Mechanisms

This study examined the spatio-temporal trajectories of the international freight forwarding service(IFFS) in the Yangtze River Delta(YRD) and explored the driving mechanisms of the service. Based on a bipartite network projection from an IFFS firm-city data source, we mapped three IFFS networks in the YRD in 2005, 2010, and 2015. A range of statistical indicators were used to explore changes in the spatial patterns of the three networks. The underlying influence of marketization, globalization, decentralization, and integration was then explored. It was found that the connections between Shanghai and other nodal cities formed the backbones of these networks. The effects of a city's administrative level and provincial administrative borders were generally obvious. We found several specific spatial patterns associated with IFFS. For example, the four non-administrative centers of Ningbo, Suzhou, Lianyungang, and Nantong were the most connected cities and played the role of gateway cities. Furthermore, remarkable regional equalities were found regarding a city's IFFS network provision, with notable examples in the weakly connected areas of northern Jiangsu and southwestern Zhejiang. Finally, an analysis of the driving mechanisms demonstrated that IFFS network changes were highly sensitive to the influences of marketization and globalization, while regional integration played a lesser role in driving changes in IFFS networks.     

World cities and international organizations: Political global-city status of Chinese cities

In this study, the authors use a political perspective to explore the relative global status of cities in China. Two questions are addressed. Firstly, by using international organizations as the subjects and quantitative analysis of the spatial distribution of their offices, the overall position of Chinese cities in the global distribution of international organizations is estimated. The results show that 22 Chi- nese cities are involved in international political affairs. Beijing, Shanghai and Guangzhou dominate these activities and have high po- litical global-city status. Secondly, through qualitative analysis of Guangzhou City, the authors explore how its status as a center for intemational organizations has been shaped in recent years. The locational decision-making process is analyzed and the factors are demonstrated at both national and city scales. The definition of international organizations as used in this study refers not only to those supranational bodies that have the ability to manage relations across states （such as the European Union）, but also those in- ter-governmental organizations （IGOs）, international non-governmental organizations （INGOs） and diplomatic representatives and delegations that today also manage and regulate relations between and among states.

The Square Kilometre Array: An International Engineering Perspective

The pace of the international Square Kilometre Array (SKA) project is accelerating, with major concept reviews recently completed and a number of technology demonstrators well underway. First-round submissions to host the telescope were lodged by six countries. The SKA timeline currently shows a site decision in 2006, and one or more technology concepts chosen in 2008. The telescope is expected to be operational, in various phases, in the period 2015–2020. This paper gives a status review of the project, and outlines engineering concept development and demonstration projects.     

基于新闻数据的新冠疫情事件下“全球-中国”国际关系变化分析方法

在新冠疫情的冲击下,国际关系错综复杂、瞬息万变,不稳定性不确定性剧增。全面及时地分析“全球-中国”国际关系变化特征,对于中国的外交发展规划具有重要的参考价值。复杂的国际关系可以分解为一系列事件单元,新闻数据中蕴含了时间、地点、人物、事物等关键信息,是构建事件的最直接、最全面的信息来源。本文以GDELT（Global Database of Events, Language, and Tone）新闻事件数据库为数据源,基于“全球-中国”的视角,利用2020年1—5月全球疫情相关新闻数据,研究新冠疫情事件背景下的国际关系的变化。本文首先以事件数量、事件强度值和事件被提及数作为关键变量,提出了国际关系的分类表达和计算模型,解决了国际关系表达模糊和难以计算的问题。然后从时空可视化角度展示疫情下国际关系的变化特征,并结合疫情期间的国际重要事件,进一步分析引起国际关系变化的原因。研究表明,采用本文方法能精确掌握新冠疫情下“全球—中国”国际关系的发展程度,发现“全球-中国”国际关系的变化规律和变化原因,具有重要的应用价值。本文的研究可以为大数据时代的国际关系研究提供一个新的视角,同时也为新闻数据的分析提供参考。
