JAPAN'S DIRECT MANUFACTURING INVESTMENT IN THE UNITED STATES

Japan is the most important foreign investor in the United States. Japanese companies are trade-oriented and have ownership-specific advantages in select industries; their US investment is aimed at protecting their market share. The distribution of Japanese plants correlates well with US manufacturing, except that the West Coast and states that aggressively sought Japanese investment have more employees in Japanese plants. Japanese presence in US manufacturing is most prominent in consumer electronics, steel, automobiles, and high-technology industries.

黄腊石滑坡基岩弯曲松弛带工程地质特性、形成机制及失稳预测

黄腊石滑坡是发育在三叠系中统巴东组砂泥岩夹灰岩构成的逆倾坡上的滑坡群,总方量约1 800×104 m3.滑坡滑带下面存在着大致连续分布的基岩弯曲松弛带.对于该松弛带工程地质特性的认识,将影响防治工程方案的设计及实施.本文通过野外工作、以往工作资料和研究成果的收集整理及再认识,对该滑坡下伏松弛带工程地质特性、形成机制及失稳预测作了一定深度的探讨,认为基岩弯曲松弛带是发生在特定的岩层中,由构造、重力、侵蚀、岩溶、风化、降雨及上部滑坡等因素共同作用的产物,工程地质环境质量较差,受重力及其上滑体滑动等因素影响,后期改造明显.在斜坡长期受重力累积变形、三峡水库运行期江水位变化及库岸再造作用下,将形成牵引式滑动.防治工程应在削方、排水等基础上,重点考虑防止库岸再造和斜坡坡脚部位变形.     

西非塞拉利昂—利比里亚盆地深水岩性油气藏成藏特征

立足于大西洋的构造演化,划分了盆地构造演化阶段,明确了不同演化阶段的构造、沉积特征,分析了漂移期岩性油气藏的成藏特征,建立油气成藏模式,指出了油气勘探的方向。研究表明,塞拉利昂—利比里亚盆地经历了裂陷期和漂移期两个演化阶段,早白垩世裂陷期,构造活动强烈,以陆相沉积为主;晚白垩世至今的漂移期构造活动弱,以海相沉积为主。赛诺曼—土伦阶海相烃源岩是漂移期岩性油气藏的主要油气来源,是油气成藏的基础;盆地漂移期广泛发育大型深水沉积体,深水沉积体是漂移期储层和岩性圈闭形成的关键;油气运移控制了岩性油气藏的成藏模式,漂移期构造活动弱,缺少油源断裂,赛诺曼—土伦阶成熟烃源岩生成的油气就近运移至烃源岩层内的岩性圈闭中聚集成藏,形成自生自储的油气成藏模式;寻找赛诺曼—土伦阶烃源岩灶内大型沉积体是盆地未来深水区油气勘探的重要方向。

Geological and geochemical indicators and prediction of deep-seated ore bodies in Jiudian gold deposit of Pingdu,Shandong Province

Based on the geology and geochemistry of gold-bearing quartz veins in the Jiudian gold deposit of Pingdu,Shandong Province,the geological and geochemical indicators of occurrence of deep-seated ore bodies in the Jiudian gold deposit have been summarized.Extent occurrence of wide,intensive,varied alteration zones around the gold-bearing quartz veins and continual presence of diorite porphyrite and lamprophyry indicate the probable occurrence of deep-seated ore bodies at depth of gold lodes.As,Sb and Hg belong to the head halo elements, and their anomalies could reveal the probable occurrence of the deep-seated ore bodies below.

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。     

New-type urbanization in China: Predicted trends and investment demand for 2015–2030

The future development of new-type urbanization has drawn great attention from both the government and public alike. In this context, the present study had three related research aims. Firstly, it sought to predict the urbanization and population dynamics in China at both national and provincial levels for the period of 2015 to 2030. Secondly, on this basis, it sought to examine the spatial variation of urbanization given the predicted national urbanization rate of 70.12%. Thirdly, it sought to estimate and evaluate the national and provincial demands of investment in the development of new-type urbanization. The main conclusions from this study were as follows: (1) The population size and urbanization rate will reach 1.445 billion and 70.12%, respectively, from 2015 to 2030. (2) The demographic dividend will vanish when the population pressure reaches its maximum. During this period, there will be 70.16 million urban population born. The suburban population that becomes urbanized will be 316.7 million, and thus the net increase in urban population will reach 386 million. (3) Although the urbanization rate of every Chinese province will increase during 2015–2030, it will do so unequally, while differences in urbanization quality among provinces will also be substantial. In some provinces, moreover, the urbanization quality is not compatible with their eco-social development. (4) A total of 4,105,380 billion yuan is required to fund new-type urbanization and the investment demand for each province varies greatly; for example, Guangdong province requires the most funding, amounting to approximately 148 times that required by Tibet, the province in least need of funding. In the final part of this study, policy suggestions concerning the investment of the new-type urbanization are put forward and discussed.
