中国跨境风电项目的建设模式、梯度转移及减排潜力研究

作为“一带一路”倡议的样板工程和旗舰项目,中巴经济走廊中的风电项目建设已经初现规模。中国在巴基斯坦的工程建设中,风电优先项目涉及的项目金额约为6.47亿元,运营期累计发电量可以达到近180亿千瓦时,可累计减少二氧化碳排放13.90兆吨。伴随跨境风电项目的梯度转移,中国可再生能源项目落地并网取决于东道国的政策制度安排、建设运营模式、设备供应体系以及电价收购协议等。本研究有助于协助沿线国家完善能源政策制度、加快清洁电力发展、应对气候变化、落实碳减排承诺,为绿色“一带一路”建设中可再生能源项目的推广提供借鉴。     

哈大巨型城市带要素集聚程度与生态环境水平关系演变

基于耦合模型和象限图法,从整体和内部分异2个角度对2000~2012年哈大巨型城市带要素集聚程度与生态环境水平演变及其关系进行分析,结果表明：哈大巨型城市带要素集聚程度呈波动上升的演变特征,生态环境则“先波动上升,后缓慢下降”,城市带整体要素集聚程度与生态环境水平间关系趋于协调,产业结构演变、资源消耗水平、经济密度是导致城市带要素集聚程度与生态环境水平协调度提高的主要驱动因子,其中产业结构演变的影响作用更加明显。城市带内部要素集聚的“四城市”格局已经形成,呈现出“核心-边缘”结构,要素集聚程度与生态环境水平可分为高级协调、要素集聚滞后、低级协调、生态环境滞后4种类型。4个区域中心城市要素集聚程度与生态环境水平关系趋向不协调,中心城市周边地区主要向要素集聚滞后型转变,资源型城市和重工业城市要素集聚程度与生态环境水平多表现为低级协调。     

长江经济带创新产出的时空演化特征及其成因

利用区位基尼系数、空间自相关、相对发展率指数（NICH指数）以及空间面板数据模型等分析方法,以长江经济带沿线38个中心城市作为空间观测单元,结合专利授权量等相关数据,研究了创新产出的时空演化特征及其成因。结果表明：2000~2013年长江经济带沿线中心城市的创新产出在整体上逐年增长,地理集中度呈现波动下降趋势;长三角地区相对发展速度较快;创新产出的空间集聚程度表现出反“Z”字形的波动上升态势;创新产出的热点区域由长三角-成渝“双核心”空间结构发展成长三角“单极突出”空间格局,且长三角热点区域范围有所增长,冷点区域则分布在长江中游地带;技术溢出、政府行为、空间区位和金融支持均对长江经济带沿线中心城市的创新产出具有显著地正向影响,经济基础对下游城市具有促进作用。根据研究结论还提出了相应政策建议。

哈大巨型城市带空间开发-经济发展-环境演变的耦合分异机制

通过构建空间开发、经济发展、资源环境水平的评价指标体系,引入耦合度概念,并应用变异系数、趋势面分析、回归分析等定量模型研究2000~2014年哈大巨型城市带空间开发-经济发展-环境演变的耦合分异特征及其影响机制,主要得到以下结论：① 2000年以来哈大巨型城市带各城市空间开发-经济发展-环境演变的耦合度均处在不同程度失调状态,且整体表现为“西高东低-南高北低”的空间格局,但耦合度水平总体趋于上升。哈长次区域和辽中南次区域以及哈大巨型城市带整体的耦合度波动性均先升高后下降,总体趋势不断向好;② 政府投入强度是2000年影响哈大巨型城市带各城市耦合度差异的重要作用因素,资本投入强度与科技投入规模是2007年、2014年2个阶段的主导影响因素,且城市发展能级差异与2007年各城市间的耦合度差异表现出一致性;③ 在政府投入强度、科技投入规模、资本投入强度等因素的共同作用下,哈长次区域空间开发-经济发展-环境演变的耦合程度出现空间分异。辽中南次区域耦合度分异的影响因素由人力资本效率和行政等级逐渐演变为以资本投入强度主导。     

“一带一路”建设研究进展

“一带一路”经历了从中国倡议到国际共识的巨大转变,正在成为世界上越来越多国家和政治领袖们探索全球经济治理新模式的平台。伴随这种转变以及“一带一路”建设所取得的成就,“一带一路”研究已经深入到除了基础科学领域外的几乎所有学科。本文根据中国知网（CNKI）数据分析了4年多来“一带一路”研究文献的特征,而后总结了与地理学密切相关的“一带一路”核心议题的研究进展。研究发现：① 自2014年以来“一带一路”研究发文量迅速上升,由2014年的1000多篇飙升到2017年的20000多篇;② 文献比较庞杂,以宏观性、战略性和一般性文献为主,舆论性很高,基于深入研究的高水平学术文献少,还不能很好地支撑“一带一路”建设;③ 对外直接投资、互联互通、“走出去”、全球化、全球治理、命运共同体、人民币国际化等得到的关注较多;④ 地理学在“一带一路”的战略内涵和理论构建、地缘政治经济分析、“中欧班列”、海上航运战略支点、海外投资模式、经贸格局及其经济影响、资源环境问题等方面研究较为深入。最后,本文呼吁加强“一带一路”的理论建构以及建设机制和国别研究,并积极开展中外学者之间“一带一路”研究对话以及合作研究。     

中国东南极地质考察20年进展与展望

在1998—2017年期间,我国组织了14次东南极地质考察,将考察的范围从中山站所在的拉斯曼丘陵向外扩展了约400 km,主要包括格罗夫山、埃默里冰架东缘-西南普里兹湾、北查尔斯王子山、布朗山、赖于尔群岛和西福尔丘陵等露岩区。通过大、中比例尺的地质编图和多学科综合研究,取得如下重要进展:(1)确定格罗夫山冰下高地为泛非期(~570—500 Ma)单相变质地体,发现镁铁质和泥质高压麻粒岩并刻画了泛非期造山的精细过程,为普里兹造山带的碰撞造山成因以及冈瓦纳超大陆的多陆块汇聚模型提供了岩石学支撑;(2)论证在印度克拉通与东南极陆块之间存在一个延长2 000 km的中元古代长寿命大陆岛弧,岛弧岩浆作用从~1 500 Ma一直持续到~1 000 Ma,提出雷纳造山带格林维尔期(~1 000—900 Ma)的构造演化可能经历了从弧陆碰撞到陆陆碰撞的过程;(3)在赖于尔群岛超高温变泥质岩中识别出早期蓝晶石的残留,确定了超高温变质作用顺时针演化的精细P-T轨迹;(4)在西福尔丘陵西南部基性岩墙群中发现了格林维尔期(~960—940 Ma)不均匀麻粒岩化,变质条件达820—870℃、0.84—0.97 GPa,认为西福尔陆块也卷入到印度克拉通与东南极陆块的碰撞造山过程;(5)在西福尔丘陵东南部浅变质冰川漂砾和松散砂中获得~3.5—3.3 Ga的古老锆石U-Pb年龄,推测在西福尔丘陵东南方向存在一个从前未知的古太古代冰下陆块。建议今后在东南极面向印度洋构造域的地质考察要进一步扩展到南查尔斯王子山、内皮尔杂岩和登曼冰川,研究工作的重点仍聚焦在南极大陆如何响应地质历史时期里超级大陆的聚散过程这一关键科学问题上,并可在以下几个方面展开:(1)太古宙古老地壳及陆核的识别与全球对比;(2)格林维尔期造山记录与罗迪尼亚超大陆汇聚;(3)泛非期造山记录与冈瓦纳超大陆汇聚;(4)显生宙冈瓦纳超大陆裂解及陆块分离。通过这些考察和研究工作,可以促使我国对南极地质科学的研究达到国际先进水平。     

The trade network of the Belt and Road Initiative and its topological relationship to the global trade network

Unimpeded trade is one of the cooperation priorities in the Belt and Road Initiative proposed by China. On 15 May 2017, the Joint Communique of the Leaders Roundtable of the Belt and Road Forum for International Cooperation reaffirmed the participants’ shared commitment to build an open economy and ensure free and inclusive trade. The Belt and Road Initiative (BRI) is not only China's new action to drive its open and global development, but also a platform for an increasing number of countries to explore free and inclusive trade and promote a universal, rule-based, open, non-discriminatory, and equitable multilateral trade system. It is therefore important to examine the topological relationship between the BRI and global trade networks. More specifically, this article first analyzes the community structure of trade networks using a community detection algorithm, and then estimates the topological relationship between different trade communities. The findings of this article are as follows. First, this research identified three trade communities and two sub-communities in the BRI trade network, in which China is the core, Russia is the sub-core of the biggest trade community, and India, United Arab Emirates, and Saudi Arabia are cores of the second trade community (South Asia-West Asia). Second, it identified five trade communities in the global trade network, centred on China, USA, Russia, India-United Arab Emirates, and Germany- Netherlands-France-Britain and other European developed countries. Third, the topological analysis indicated that in the global trade network, most BRI countries are attracted by the core nodes of the BRI regions, such as the China, Russia and India-United Arab Emirates core nodes, and have strong trade contacts with BRI countries. Most Central-East European countries are mainly attracted by Germany-Netherlands-France-Britain and other developed European countries with a low penetration of BRI trade. Although some Southeast Asian countries are incorporated into the Asia-Australia-South Africa community with China as the core, they still need to strengthen trade linkages with BRI countries.     

Tracking embodied carbon flows in the Belt and Road regions

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.     

Chinese overseas industrial parks in Southeast Asia: An examination of policy mobility from the perspective of embeddedness

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.
