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

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.     

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

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。

中国外商直接投资的地域结构研究

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。     

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

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.

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。     

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

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.     

Governing a city of unicorns: technology capital and the urban politics of San Francisco

San Francisco is now widely considered to be the most important city in the world for the location of new technology start-up firms, especially high valuation “unicorns,” and is increasingly seen as both a locational and metaphorical extension of Silicon Valley. In this paper, I trace some of the political strategies and tensions that have accompanied the city’s prominence in this area, and in particular the distinctive role of technology and venture capital in the political economy of urban development. The paper has four empirical sections. It describes (1) the political machinations surrounding the 2011 and 2015 municipal elections, which saw the election of Ed Lee as Mayor with significant support from individual technology investors such as Ron Conway and Marc Benioff, and accompanied by various “tech-friendly” policy shifts; (2) the foundation of the “tech chamber of commerce” sf.citi as a means of enhancing the policy influence of the tech industry in San Francisco; (3) the introduction of a low taxation regime in the city’s Central Market area that has attracted technology companies such as Twitter as tenants; and (4) the urban policy tensions associated with the evolution of new “sharing economy” firms such as Uber and Airbnb, which have aggressively challenged municipal regulations in the taxi and property rental fields. Throughout these machinations, we can see a reshaping of capital fractions, with venture and angel capital increasingly involved in reengineering the labor, housing, and public transport markets of the city in order to circumvent the accumulation problems that tech investors had suffered in the earlier dot.com failures.
