As an important innovation flow, venture capital has been examined in urban network research. However, the segmentation of capital categories and the cross-scale connection of capital remain scarcely analyzed. This study focuses on the structure and industry differentiation of venture capital flows in the Guangdong-Hong Kong-Macao Greater Bay Area(GBA) and its cross-scale network characteristics. Based on a venture capital database covering capital amount, investment subject address information,...  相似文献   

URBAN CHANGE,CIRCUITS OF CAPITAL,AND UNEVEN DEVELOPMENT*     

David Wilson 《The Professional geographer》1991,43(4):403-415

The circuits of capital/uneven development model is widely used in geography, urban planning, and the social sciences. Its principal weakness is its marginalizing of local influences in explaining the intensity and patterning of metropolitan investment. A deeper consideration of local culture, politics, and biographies is needed to sensitize the model to the particularities of place. Local creative actors set in motion place-specific forms of change whose logic is tied to structured circumstances.  相似文献

不同等级城市的农民工人力资本增长差异及影响因素——基于河北省清苑县的调查分析   总被引：1，自引：0，他引：1  

朱华晟  徐凡  赵雪平  李杰 《地域研究与开发》2017,36(1)

农民工外出务工动机正由"生存型"向"发展型"转变,人力资本成为影响其城市融入的重要因素。通过对河北省清苑县的分层随机抽样调查,运用数理统计和对比分析法研究外出农民工的人力资本增长及其作用机理。结果表明:相对于进入全国中心城市和其他中小城市的农民工群体,区域中心城市的农民工技能增长的比例最高。在人力资本增长途径上,非正式学习途径效果突出,正式培训对人力资本增长的效果以区域中心城市最为显著,不仅进入该类城市的农民工能够获得更多的正式培训机会,而且企业对员工的培训频次及培训专业化程度均较另两类城市高。非正式学习受农民工学习主动性的影响,Logistic回归显示企业培训频次对技能提升主动性发挥正向作用且效果最强,而地方文化设施环境与农民工技能提升的主动性呈现负相关,全国性中心城市尤为明显。  相似文献

Chocolate in China: the cadbury experience     

L.J. Wood  S. Grosvenor 《The Australian geographer》1997,28(2):173-184

Since 1979, China's Open Door policy has attracted increasing foreign investment. To maintain global competitiveness, the British confectioner, Cadbury, authorised its Australian subsidiary to develop a chocolate plant in China. This paper details the decision‐making processes that eventually led to a new factory on a greenfield site near Beijing. It also illustrates some of the adaptations that Cadbury has had to make in its product and production procedures in order to match its own standards for dairy milk chocolate and yet accommodate guo qing (the special situation in China).  相似文献   

中国城市网络团购市场供需协调性评价——基于30个省会城市的实证分析

以30个省会城市为研究对象,从宏观尺度揭示中国城市的网络团购市场供给规模与需求潜力的协调性特征。结果表明:团购市场供给规模较大的城市主要集中在中国东部和西部地区;东部地区城市的供给规模和需求潜力的协调发展程度整体较好,供需失调现象明显的城市主要集中在西北地区;团购市场供给规模及其与需求潜力的协调性均遵循以经济发展水平为标尺的等级式扩张路径。餐饮、娱乐和旅游酒店3类团购市场供给规模相对需求潜力表现出了较明显的过剩现象。城市经济发展水平是团购市场供需协调发展的根本动力,团购市场供给规模和需求潜力水平是团购市场协调发展的直接动力。  相似文献   

Dams and population displacement on China’s Upper Mekong River: Implications for social capital and social–ecological resilience     

《Global Environmental Change》2016

China is home to nearly half of the world’s 50,000 large dams, which provide irrigation, flood protection, and hydroelectricity. Most of these projects involve substantial population displacement, which can disrupt social capital, the webs of interdependence and support that community members maintain with one another through relationships of trust and reciprocity. We use new empirical evidence to examine the association between dam-induced displacement and social capital in China and interpret our findings in the context of social–ecological resilience theory. Our focus is on agricultural households on the Upper Mekong River, where four large hydropower dams have been constructed over the past twenty years.Our broad finding is that resettlement is associated with diminished social capital, as measured by two key indicators: inter-household exchange of financial resources, and inter-household exchange of agricultural labor. These effects differ across the four dam sites in the study based on local economic conditions and changes in resettlement policy. We find that population resettlement is associated with markedly lower levels of agricultural labor exchange. In an economically under-developed setting, this reduces the depth and breadth of social support that agricultural households rely on to produce crops for subsistence and income. This in turn diminishes social–ecological resilience because social capital is a key factor that helps agricultural or resource-dependent communities manage risk and adapt to changes and stressors.We consider the policy implications of our findings in the context of scientific and industry efforts to minimize social harm, promote economic vitality, and improve the sustainability of hydropower as a form of renewable energy.  相似文献
