我国贸易条件与贸易利益增长关系的研究 总被引:1,自引:0,他引:1
长期以来,贸易条件被认为是衡量一国获取贸易利益大小的一项重要指标。文章从价格贸易条件、收入贸易条件及单要素贸易条件的涵义出发,进行了贸易奈件和贸易利益的相关关系分析。分析表明,要全面准确衡量一国的贸易利益必须把价格贸易条件、收入贸易条件和单要素贸易条件这几者结合起来综合考虑,并通过实证研究揭示了我国贸易条件下的静态贸易利益和动态贸易利益现状及制约贸易利益增加的因素。在分析基础上,提出进一步改善我国贸易条件,更多地分享国际贸易利益的措施和建议。 相似文献

Environmental Kuznets Curve with Adjusted Net Savings as a Trade‐Off Between Environment and Development

The Environmental Kuznets Curve (EKC) hypothesises that emissions first increase at low stages of development then decrease once a certain threshold has been reached. The EKC concept is usually used with per capita Gross Domestic Product as the explanatory variable. As others, we find mixed evidence, at best, of such a pattern for CO2 emissions with respect to per capita GDP. We also show that the share of manufacture in GDP and governance/institutions play a significant role in the CO2 emissions–income relationship. As GDP presents shortcomings in representing income, development in a broad perspective or human well‐being, it is then replaced by the World Bank's Adjusted Net Savings (ANS, also known as Genuine Savings). Using the ANS as an explanatory variable, we show that the EKC is generally empirically supported for CO2 emissions. We also show that human capital and natural capital are the main drivers of the downward sloping part of the EKC. 相似文献

中韩自由贸易区的建立对中韩两国净出口与就业影响的实证分析 总被引:1,自引:0,他引:1
本文主要运用计量经济学的方法就中韩建立自由贸易区对中韩两国净出口与就业的影响进行了实证分析。实证分析主要分三步:第一步,分析了FTA的建立对两国之间净出口的影响;第二步,分析了净出口的变动分别对中韩两国GDP的影响;第三步,分析了两国GDP与失业率之间的关系,从而得出FTA的建立对两国就业的影响。结论为:若在2009年中韩建立自由贸易区,中国对韩国的贸易逆差会减少64.9196亿美元,韩国对中国的贸易顺差会减少64.9196亿美元;自由贸易区的建立会使中国的GDP增加约0.426%,韩国的GDP减少约0.938%;会使中国的失业率下降约0.069%,韩国的失业率上升约0.157%。 相似文献

The Welfare Economic Theory of Green National Accounts 总被引:4,自引:3,他引:1
Partha Dasgupta 《Environmental and Resource Economics》2009,42(1):3-38
This paper takes a critical look at the literature on green national accounts. The problem studied is to find a linear index of economic variables that responds to perturbations in the same direction as social well-being. The thesis of a large literature, that net national product (which is a flow) is that index in closed economies, is shown in some interpretations to be simply false and in others to suffer from deep estimation problems. It is argued that capital depreciation using shadow prices should certainly be included in national accounts, but that the right welfare index is a comprehensive measure of wealth, defined as the shadow value of an economy’s stock of all capital assets. It is shown that comprehensive wealth is usable as a criterion for policy evaluation as well as for determining sustainable economic development. 相似文献

In this paper, we investigate the organizational determinants of safety technology adoption. To shed light on this important question, we develop and test nine hypotheses. Results are based on a national survey of motor carriers sponsored by the United States Department of Transportation. Using a Poisson regression model, we find statistical support for seven hypotheses. A key finding is that prior safety performance influences a firm’s adoption of safety technologies. Additionally, a firm’s optimism about the potential for safety technologies, its technological innovativeness, and its level of comfort with new technologies contribute to its safety technology adoption decisions. 相似文献

Many existing studies on emerging markets and firms have concentrated on the separate effects of institutional reforms and quality of the institutional infrastructure for attracting inward foreign direct investment (FDI) and fostering outward FDI. We argue that both these perspectives should be considered in an interplay, as there are links between inward and outward FDI in a country's economic development, which is captured by the investment development path (IDP) concept. Moreover, while predominant attention has been paid to emerging markets, little has so far been done to evaluate the sustainability of the institutional development, including later post-transition stages. We extend the IDP with insights from the institutional theory and conduct a comparative analysis of the effects of institutional reforms on IDP paths of ten Central and Eastern European (CEE) post-communist European Union (EU)-members. We find that while most of the studied post-transition economies follow a quadratic relationship between the net outward investment (NOI) position and each country's economic development, the role of institutional reforms is not in all cases accelerating the movement through the stages of the IDP. We attempt to explain the ambiguous role of institutions in an ensuing detailed discussion of the investigated countries. 相似文献
