论汽车工业空间组织之变化——生产方式转变的影响

汽车工业出现一百多年来空间组织发生了几次重要变化,而生产方式的转变是导致空间演化的主导因素之一。本文首先回顾了８０年代以前世界汽车工业空间组织的主要特征,并将其演化过程归纳为四个阶段,即初始分散阶段、大规模生产初期的高度集中阶段、“核心—边缘”结构阶段和网络化分散阶段。其次介绍了８０年代以来世界汽车工业发展的新特点,特别是精益生产方式的广泛扩散。最后归纳了新的生产方式下汽车工业空间组织的影响因素和特征,即网络化聚集,并简要地讨论了这种发展趋势对中国汽车工业的启示。

“一带一路”倡议下中国与重要节点地区的贸易格局及影响因素--以外高加索国家为例

外高加索国家地处欧亚十字路口,是古丝绸之路上的重要国家,也是“一带一路”的核心节点,区位战略意义重大。该文分析了外高加索三国自1991年独立以来中国与其贸易发展历程,借助HM指数和贸易互补性指数,从贸易总体格局和贸易商品特征两个角度分析双向贸易关系,并探究了影响其贸易发展的因素。结果表明:1)中国与外高加索三国长期保持贸易往来,贸易总额呈波动攀升趋势,阶段性特征明显;贸易差额起伏变化,整体长期维持贸易顺差状态;外高加索三国对中国的贸易依赖性显著大于中国对其依赖性。2)中国对外高加索三国出口商品互补性显著高于进口互补性,说明与作为中国进口商品来源国相比,外高加索三国作为中国商品的消费市场更具优势;中国对外高加索三国出口商品类型较为相似,结构呈集中与多元并存态势,主要出口商品逐步由资源、劳动密集型的低附加值商品向技术密集型等高附加值商品转变,而中国自外高加索三国进口的商品类型虽有所扩展,但主要类型仍较为单一,高度集中于未加工或半加工类资源型商品。3)地理距离、政局稳定性、产业结构、地缘关系、贸易环境及便利性是影响中国与外高加索三国贸易发展的主要因素。

“一带一路”沿线地区隐含碳流动研究（英文）

In the past few decades, economic globalization has driven rapid growth of cross-border trade and a new international division of labor, leading to increasing inter-country embodied carbon flows. Multi-region input-output(MRIO) analysis is used to identify embodied carbon flows between major world regions, including seven regions along the Belt and Road(BR), and the spatial distribution of production-and consumption-based carbon intensities. The results show that current embodied carbon flows are virtually all from BR regions to developed countries, with more than 95% of world net embodied carbon exports coming from BR regions. Consumption in the United States and European Union countries induce about 30% of the carbon emissions in most BR regions, indicating that the former bear a high proportion of consumers' responsibility for the carbon emitted in the latter. For this reason, measuring environmental responsibilities from consumption rather than a production-based perspective is more equitable, while developing countries should be given a louder voice in the construction through dialogue and cooperation, in part in the context of the Belt and Road Initiative, of an inclusive global climate governance system.     

中国在东南亚的海外经贸合作园区——以嵌入性视角检验政策移动性（英文）

The development of overseas industrial parks is a key component of the Belt and Road Initiative and an expected experimental way of promoting inclusive globalization by inventing new forms of cooperation between China and local host countries. Policy mobility, a classic theory within international political geography addressing the connection between local and global policies, has implications for overseas industrial parks development. In this paper, we argue that policies are not easily moved directly from one place to another; instead, policies are embedded due to the role of local actors in policy mobility. This article first provides an overview of seven China-Southeast Asia economic and trade cooperation zones identified by the Ministry of Commerce, and analyzes their key participants. It then discusses policy mobility by looking into the roles of revenue, land, and talent in developing these industrial parks. The paper finds that these parks face challenges, such as the complicated geographical environments of host countries, huge pressure from enterprise investment capital, the lack of overseas service platforms, and underdeveloped agglomeration economies. In the light of the current situation, policy suggestions for the future sustainable development of overseas industrial parks are put forward.     

1980-2017年中国碳强度关键影响因子变化特征

The Chinese government ratified the Paris Climate Agreement in 2016.Accordingly,China aims to reduce carbon dioxide emissions per unit of gross domestic product(carbon intensity)to 60%–65%of 2005 levels by 2030.However,since numerous factors influence carbon intensity in China,it is critical to assess their relative importance to determine the most important factors.As traditional methods are inadequate for identifying key factors from a range of factors acting in concert,machine learning was applied in this study.Specifically,random forest algorithm,which is based on decision tree theory,was employed because it is insensitive to multicollinearity,is robust to missing and unbalanced data,and provides reasonable predictive results.We identified the key factors affecting carbon intensity in China using random forest algorithm and analyzed the evolution in the key factors from 1980 to 2017.The dominant factors affecting carbon intensity in China from 1980 to 1991 included the scale and proportion of energy-intensive industry,the proportion of fossil fuel-based energy,and technological progress.The Chinese economy developed rapidly between 1992 and 2007;during this time,the effects of the proportion of service industry,price of fossil fuel,and traditional residential consumption on carbon intensity increased.Subsequently,the Chinese economy entered a period of structural adjustment after the 2008 global financial crisis;during this period,reductions in emissions and the availability of new energy types began to have effects on carbon intensity,and the importance of residential consumption increased.The results suggest that optimizing the energy and industrial structures,promoting technological advancement,increasing green consumption,and reducing emissions are keys to decreasing carbon intensity within China in the future.These approaches will help achieve the goal of reducing carbon intensity to 60%–65%of the 2005 level by 2030.     

新时期我国区域空间规划的方法论探讨——以"西部开发重点区域规划前期研究"为例

地理科学的中国进展与国际趋势

中国地理学取得了骄人的进展,表现在科研方向的突破、对国家建设的贡献、研究手段的革新、对科学和教育的贡献、对社会的贡献等方面。但当前中国也存在基础研究薄弱、学科整合不足、学术走向迷茫、竞争能力堪忧、全球视野欠缺、地理教育错位等问题。国际地理学对科学界所确定的关键研究问题表示出更大的关注,科学界也将更加了解地理学及其视角能对科学知识做出的贡献。地理学所关切的科学问题直指今天决策者的紧迫需求。地理学家以多种方式对解决实际问题做出贡献。国际地理学的发展聚焦在：揭示复杂系统中的不平衡和动态,认识全球化 (包括环境、经济、人口、政府和文化等)的潮流及其影响,建立从地方到全球的空间连续系列研究,利用包括时间系列数据在内的纵向数据进行过程比较研究,加强地理学理论、技术和研究成果对决策的影响,加强地理教育,包括努力提高公众的地理学能力,改进高等院校地理学家的训练,提高地理理解力,加强地理组织机构。
