矿产地质勘查的层次性、投资规划及快速预查          下载免费PDF全文

冯建忠  续婧 《地质找矿论丛》2008,23(1):67-72

探矿工程是一个逐步缩小工作范围、由浅入深、由表及里、逐渐加密的取样工程.地质勘查是分阶段、有层次进行的,按工作面积由大到小分为5个层次.文章探讨了每个工作层次的工作平台、主要工作内容、野外工作量和预期目标.根据投资经验统计,一个中小型矿床的勘查从选区申请立项到详查结束,用于纯地质勘查上的费用大体需要1330万元(选区-预查阶段130万,普查-详查阶段1200万元).认为项目建设与找矿前景评价应抓住3个关键:建立专家群体(快速选区)、建立和完善研判准则和流程(快速研判)、建立精干队伍野外调研(快速评价).建议组建3人快速勘查组半年完成野外预查:2个月完成地质、化探调查,2个月完成靶区验证.  相似文献   

Foreign Direct Investment,Ecological Withdrawals,and Natural-Resource-Dependent Economies     

Michael A. Long  Paul B. Stretesky  Michael J. Lynch 《社会与自然资源》2017,30(10):1261-1276

This article examines the relationships between foreign direct investment (FDI) and natural resource depletion and natural resource rents for a longitudinal (2005–2013: N?=?125 nations) sample of less developed countries (LDCs). Theoretically, we argue that FDI contributes to increased ecological withdrawals and dependence on the natural resource sector for economic growth within countries. We hypothesized that LDCs with higher levels of FDI would also have higher levels of natural resource depletion and income (i.e., rents). We assess whether this hypothesized relationship holds across nations in our sample for four different natural resource depletion and rents measures (energy, forest, mineral, and total natural resources). We find strong support for our hypotheses regarding natural resource depletion and resource rents, with the exception of energy rents. The outcome lends support to the ecological withdrawal and ecostructural theory of foreign investment dependence perspectives.  相似文献

焦华富 《地理研究》1997,16(3):32-38

改革开放以来,我国引进外资工作取得了较大进展。然而,外资地域分布的不平衡,成为导致区域经济发展水平差距拉大的一个重要原因。如何改善外资地域分布结构,成为各界关注的焦点之一。文中采用定量和定性相结合的方法,研究了中国外资地球分布的现状及特点,分析了外资地域分布的动态变化趋势,并在此基础上提出若干改善外资地域分布结构的举措。  相似文献   

Source Country Differences in the Spatial Distribution of Foreign Direct Investment in the United States     

Breandn hUallachin  Neil Reid 《The Professional geographer》1992,44(3):272-285

Statistical analysis of foreign direct investment in the United States reveals source country differences in interstate location. We relate these differences to the knowledge foreign investors have of the United States. Regression analysis indicates a significant concentration of foreign investment from individual countries in larger states and in border states. Worldwide investment in the United States does not show these preferences. Investment from Japan and Canada accounted for most of the interstate dispersal of foreign employment in the 1980s.  相似文献

Firm entry modes and Chinese business networks: Malaysian investments in Vietnam          下载免费PDF全文

Guanie Lim 《Singapore journal of tropical geography》2016,37(2):176-194

This paper examines the Malaysian Chinese firms that have expanded into Vietnam. Based on research and qualitative personal interviews with Malaysian Chinese firms that have invested in Vietnam, the paper unpacks the entry modes that these firms have undertaken. It argues that the Malaysian Chinese firms prefer joint ventures in their Vietnamese businesses to wholly‐owned subsidiaries and personal direct investments. This paper also argues that such investments are often embedded in social and intraethnic ties, which connect Malaysian Chinese firms with Vietnam's ethnic Chinese businessmen. To this end, these firms tend to rely on informal ties and nonmarket institutions in the form of the ethnic Chinese business networks. Nevertheless, the Malaysian Chinese firms are not averse to collaborating with nonethnic Chinese firms that enjoy a good relationship with the Vietnamese state. This observation is especially marked in the property and construction, and finance sectors.  相似文献   

东北三省对外直接投资空间格局及影响因素   总被引：4，自引：4，他引：0  

郑蕾  刘毅  刘卫东 《地理科学》2016,36(9):1329-1337

对外直接投资不仅是东北三省建立全方位开放型经济体制的必经阶段,也是实现全面经济振兴的重要契机。在中国进入对外投资加速发展阶段的背景下,“一带一路”战略、东北亚经济圈建设等为东北三省对外直接投资发展提供了机遇。利用2003~2014年的省际对外直接投资规模、境外投资机构等数据,全面分析了东北三省对外直接投资的发展路径、空间特征及其在国内地位,并采用地理加权回归（GWR）模型深入地分析了东北三省对外直接投资的关键影响因素及其时空差异,最后提出相应的空间发展战略及政策建议。研究表明：① 东北三省对外直接投资主要集中在农、林、矿等资源型行业,具有显著的贸易服务、市场服务特征,并且对政府和国有经济的依赖较大;② 技术水平和金融环境对东北三省对外直接投资的推动力仍有较大的提升空间;③ 未来东北三省应推进企业联合投资和空间差异化投资战略,发挥国有企业的投资带动作用,加强对科技型企业和技术追寻型对外直接投资的鼓励和支持。  相似文献   

Visa restrictions and economic globalisation     

《Applied geography (Sevenoaks, England)》2017

The cross-border mobility of people, goods and services, and capital has expanded enormously both in intensity and diversity over recent decades. States have a general interest in facilitating these flows in order to benefit from economic globalisation. Yet, mainly due to security concerns, most governments grant visa-free mobility only very selectively. Drawing on a new bilateral visa policy database covering up to 194 destination and 214 origin countries over the 1995 to 2013 period, our analysis finds that the introduction of a visa restriction by a destination country for citizens from a particular origin country deters tourism inflows by about 20 per cent. Visa restrictions also reduce bilateral trade and foreign investment, but to a smaller extent than previous studies have suggested. We further find that some of the deterred flows in tourists and goods and services are redirected to other (visa-free) destinations. This deterrence-cum-deflection effect of restrictive visa policies implies significant economic costs for both visa-issuing and visa-targeted countries, but it creates some positive externalities for countries with a more liberal visa policy. Liberalised visa policies would in particular help poorer countries to partake more in the benefits of economic globalisation.  相似文献   

中国地质工作转型升级中的资金投入特征     

姜杉钰  王峰  樊笑英 《地质论评》2022,68(6):2022112003-2022112003

通过对当前地质工作转型升级时期的资金投入分析,梳理了财政投入和社会资金的现状特征和问题,进而提出了对策建议。研究结果显示,中国的地质工作正处于转型升级期,在资金投入上主要表现出资金投下滑总体趋势放缓、矿产勘查资金供需矛盾突出、新旧动能转换引领投资分化、科技和信息化投入仍需提升、投入空间格局正发生转变五大特征。研究认为,为进一步优化资金投入以适应新的发展形势,应该以中长期战略引领投资布局,强化两级财政的协同配合,多措并举吸引社会资本注入,完善财政投入评估调整机制。  相似文献   

哈萨克斯坦主要矿产资源特征及矿业投资环境     

高永伟  刘明义  张丹丹  张宇轩  李旭拓  曹凯 《地质与勘探》2022,58(2):454-464

哈萨克斯坦地处中亚核心位置,是丝绸之路经济带的重要节点和战略枢纽,具有丰富的矿产资源,地缘政治经济意义重大,是中国企业开展国际矿业投资合作的重要目标国之一。本文在系统梳理哈萨克斯坦基本国情、主要矿产资源特征及开发现状、地质工作程度和地矿管理体系等基础上,对哈萨克斯坦的矿业投资环境进行了评价,分析了矿业投资的有利和不利条件。研究认为哈萨克斯坦矿产资源禀赋优势突出,油气、铀、铬、金、钨、铅、锌及铜等矿种的资源储量居世界前列;全国仅有10%～15%的已探明矿产资源处于开发阶段,采矿业发展潜力巨大;哈萨克斯坦的总体投资环境优越,吸引外资力度逐渐加大,矿产勘探开发水平不断提升。但中国企业开展矿业投资也存在竞争力不足,以及面临政策法规不稳定、地质技术资料不可靠及运营等方面的风险。为此,建议中国投资者一方面要加强对哈萨克斯坦优势矿产的投资力度,积极拓展合作方式及合作领域;另一方面要注重与哈萨克斯坦各利益集团建立良好关系,结合企业优势,综合评价矿业项目,做好风险预警防范;同时,在投资过程中要尊重地方文化习俗,积极履行社会责任。  相似文献
