天津市服务业利用外商投资的实证分析     

王艳红  李伯辰  张芃 《地域研究与开发》2015,(3):34-38

服务业的发展是促进全球经济增长的重要力量,发达国家普遍呈现出产业结构高级化特征。利用外商投资可以促进中国服务业的发展,是加快经济发展的有效手段。通过对天津市服务业发展以及服务业利用外商直接投资现状的分析,对服务业外商直接投资与经济增长的关系进行了实证研究。研究结果表明:服务业外商直接投资不仅促进了天津经济的增长,同时,还对资本积累、产业结构、技术水平、就业程度及人力资本产生了不同程度的促进作用;技术水平进步、就业水平的提高、人力资本的提升又将带动天津经济增长。天津市应发挥现代服务业发展的优势,发挥天津自贸区的区位优势和政策优势,积极承揽国际服务外包。  相似文献   

Scientific advice in integrated ocean management: The process towards the Barents Sea plan   总被引：1，自引：0，他引：1  

Maaike Knol   《Marine Policy》2010,34(2):252-260

It is widely held that integrated management of ocean areas needs to be based on integrated scientific advice. Such advice crosses disciplinary and traditional sector boundaries. This paper aims to provide insight into the role of science and scientific knowledge in a process towards integrated ocean management. It does so by exploring the organization of the process towards the integrated management plan for the Barents Sea-Lofoten area in Norway. It sheds light on the complexity of management questions in a context characterized by uncertainty and political controversy, largely concerning petroleum activity. Scientists were asked to provide a dynamic view on these issues and have delivered important material that furthers the task of policy development. However, there is a persisting lack of understanding about the consequences of human impact on the ecosystem. The paper finishes by pointing at the need for a larger societal discussion on what activities we consider appropriate, considering the limits of science to provide the knowledge base for questions that transcend the environmental domain.  相似文献   

上海外资生产空间演变及影响因素   总被引：6，自引：0，他引：6

利用2004 年经济普查数据对上海制造业外资企业的空间分布、区位选择及其空间效应进行了研究。空间分布结果表明,20 世纪90 年代以来,上海外资企业在分布上表现出明显的郊区化和向近郊区局部地区(尤其是园区和新城) 集聚的特征,并形成了沪西南、浦东和沪西北3 大集聚区;制造业外资企业的分散和集聚推动了上海外资生产空间的郊区化重组。对制造业外资企业区位选择影响因素的分析显示：上海制造业外资企业区位选择是经济全球化与地方政府互动的过程;具体来说,传统区位因素作用在逐渐减弱,制度因素和集聚因素的作用在不断增强;制度因素内部产业优惠政策对外资的吸引力强于空间优惠政策,而国家级园区优惠政策对制造业外资企业(尤其是高技术外资企业) 的吸引力则强于市级园区,上述研究对上海未来的产业及外资引进政策都具有重要的参考意义。  相似文献   

金融危机下国家大规模投资政策模拟   总被引：2，自引：0，他引：2

构建了一个中国多区域可计算一般均衡模型(MReCGE-C),利用该模型分析了我国应对国际金融危机的大规模投资政策。MReCGE-C根据城乡属性和年龄结构对居民进行了分组,放松了要素流动的限制,使劳动力和资本可以同时跨区域跨部门流动,并设计了一种基于居民终生效用的区域均衡机制,通过区域差距变量可以调控和测度区域差距。最后利用MReCGE-C模型针对国家大规模投资计划下的3种典型投资方案进行了模拟。结果发现在等量新增投资下,针对中部地区投资方案的GDP增长率高于针对中西部和全国投资方案的GDP增长率,同时针对中部地区投资方案对于城乡就业的拉动也要优于其余两种投资方案,而且可以实现缩小区域差距的目标。综合比较,目前国家大规模投资的优势应该指向中部地区。  相似文献

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.  相似文献

基于重心模型的环境污染和治理投资偏离分析     

杨磊  高向东 《亚热带资源与环境学报》2012,7(2)

利用重心的概念和模型,采用2000-2009年各省工业废水、工业废气和工业固体废弃物的排放量和污染治理投资额等数据,计算出各自的重心和重心演变路径．从移动方向、移动距离和相互关系3个方面分析环境污染重心和治理投资重心各自的动态变化和空间演变轨迹,结果显示：2000-2009年,工业废水、废气和固体废弃物污染重心从移动方向来看总体向西部偏移,而且移动距离有快速西移的趋势,表明当前西部地区在环境污染方面有加重的趋势．另外,环境污染重心和投资治理重心之间存在偏离,例如,工业废水排放重心偏北,而工业废水治理投资重心偏南,并且与工业废水重心相比,工业废气和工业固体废弃物排放重心和治理投资重心偏离度要小．  相似文献

The article discusses the importance of services as agents of internationalisation. Services are seen as dynamic agents of change, and services and commodities are considered composite in production processes. Modes of entering the global scene such as trade in services, foreign direct investment, forming of alliances, franchising and intrafirm trade are focused on, and limits to globalisation are highlighted. Some services, particularly advanced business services, more easily fall prey to institutional and cultural constraints than others. Empirically, Norway is analysed as an arena of international services against the background of its historical tradition particularly in shipping and affiliated activities. Recently, however, manufacturing has gained in importance, mainly in exports and to a lesser extent in imports, due to the petroleum economy. This appears to indicate that export of services has lost momentum over time. The development profile in shipping is highly negative. The negative picture changes somewhat when not only the trade balance, but also investment abroad is considered. In this respect, services have grown in relative importance, notably in the financial sector and in telecommunications. When juxtaposing outgoing and incoming investments, petroleum-related services have gained an increased export and investment surplus in recent years, from a balance in the mid-1990s.  相似文献   

基于可达性分析的高速公路投资空间溢出效应   总被引：1，自引：1，他引：0

基于可达性分析方法,探讨新建交通基础设施投资给邻近地区带来的空间溢出效应及其特征。以2005-2009年江苏省各市新建高速公路为例,通过GIS 空间分析模型、经济潜力指数及情景分析法,得到江苏各市新建高速公路投资建设带来的经济潜力收益值,并在此基础上应用平均溢出效应模型得到区际可达性溢出矩阵,结合各地交通投资与溢出效应货币化模型将区际溢出矩阵货币化,得到区际交通投资矩阵来重新分配各市交通投资成本,以此表示交通投资空间溢出效应。结果显示：可达性溢出效应传递基本上随着到新建高速公路距离增加而衰减,然而各市新建高速公路在邻近地区产生非均衡性的溢出效应,新建高速公路方向、区位以及高速公路网络体系影响了溢出效应强度分布。中间地区交通建设更有助于推动边缘地区可达性水平提高,其交通投资溢出效应普遍比边缘地区规模大,溢出投资占实际投资比重高,区域边缘地区多数为溢出效应的输入地区。  相似文献
