中国吸引外资的浪潮对东南亚国家和地区的影响

中国吸引外资的浪潮引起了人们普遍的忧虑:中国吸引外资的浪潮是否会导致流入东南亚其他国家和地区的外资逐渐减少。本文在假定外资的供应是在有弹性的前提下,利用对外投资区位决定因素的模型,运用固定效应分析方法来检验中国吸引外资与东南亚吸引外资间的关系其结果显示,在1986年至2001年间,中国吸引外资的增长实际上提高了邻国经济吸引外资的能力, 而不是排挤了邻国外资的流入。这很可能是因为各国并没有在市场寻求型对外直接投资和资源寻求型对外直接投资之间竞争,唯一具有竞争性的部分很可能是出口加工。由于中国在电子产品方面恰恰与其他国家互补,因而与其他国家正在形成区域生产一体化体系。中国在其他的出口导向型产业中可能出现吸引外资的替补效应,但是这种效应还不足以影响到结果。

山东地区城市天然需求负荷与气温关系研究

作为清洁能源的天然气,近年来在山东的销售量持续增长.天然气的负荷需求主要受地区气象条件、工业企业生产情况、居民生活习惯、价格水平、节假日等多种因素的影响,其中气温是造成城市天然气短期负荷波动的主要原因之一.本文研究山东省天然气市场需求量与气温之间的关系,对天然气日均负荷进行周期分析,找出天然气日均负荷变化与日均气温之间的相关关系,为天然气公司进行地区性天然气计划平衡决策提供基础信息参考.     

近期国际石油价格回顾与预测

8月份,美国经济数据好转提振了人们对世界经济恢复前景的信心,加上国际能源机构（IEA）上调全球石油需求预估,以及美元下跌等因素的影响,国际原油价格走势较为强劲,大部分时间维持在70-75美元／桶波动。美国西得克萨斯轻质原油（WTI）、英国布伦特原油和亚洲迪拜原油的现货平均价格分别为71．05、72．83和71．34美元／桶,较7月份分别上升了6．95、8．22和6．52美元／桶。     

不同所有制企业创新主体地位评价 ——规模与效率双重视角的研究

推动企业成为创新决策、研发投入、科研组织和成果应用的主体,是实施创新驱动发展战略的关键。针对企业创新主体地位较难衡量且缺乏考虑企业创新效率的问题,从规模视角入手,基于创新价值链分析,通过区分企业所有制性质,研究企业创新主体地位评价指标体系和评价方法。同时,结合BCC-DEA模型和DEA-Malmquist指数,从创新效率角度系统探讨企业创新主体地位。以上海为例的实证结果表明,上海企业在研发投入端的创新主体地位相对突出,但呈不断弱化趋势,尤其是R&D经费增长显著落后于科研机构和高等院校;在以发明专利为代表的产出端,企业创新主体地位尚不明显,且同样存在比重下滑迹象。外资企业年度创新效率表现最优,内资企业处于明显劣势,但得益于技术效率增长,科技创新全要素生产率保持年均微幅增长,而港澳台商投资企业创新效率存在递减态势。最后提出加强科技资源配置、挖掘科技产出、加大科技成果转化力度等建议。     

Close relationship with the supervisor may impede employee creativity by suppressing vertical task conflict

Leader‐member exchange as a form of supportive leadership is expected to foster employee creativity. However, empirical evidence suggested this relationship is complex. This study attempts to address this complexity by proposing and testing a curvilinear mechanism, which attenuates the overall positive effect of LMX on creativity by transmitting a curvilinear indirect effect via vertical task conflict. Results drawn from a sample of 276 supervisor–subordinate dyads provided support for the hypothesized curvilinear indirect effect. Specifically, LMX was found to negatively influence employee creativity by suppressing vertical task conflict for subordinates in high‐quality LMX relationships, while the indirect effect was not significant for subordinates in low‐quality LMX relationships.     

Quantitative Analysis of Foreign Trade and Environmental Efficiency in China

This article analyzes the relationships among trade, the economy, and environmental quality in China. First, in the context of these relationships, the Super-SBM model is used to calculate the environmental efficiencies of thirty Chinese provinces and cities to obtain the degrees of regional disparity. Second, China’s provincial panel data from 2003 and 2012 are used to establish an influential factor indicator system of environmental efficiency. A section-weighted fixed effect model then provides insights about influential factors such as spatial heterogeneity. Third, the article establishes a variable coefficient model to identify the relationships among the objects of the study and divides the Chinese regions into four types. The suggestions include enhancing environmental and business regulations to ensure equilibrium between trade, the environment, and local economies.     

Carbon Markets in China: Development and Challenges

China is attempting to initiate its own carbon market—an important market-based policy instrument which would determine the fate of global climate policy as the largest emitter of carbon dioxide across the world. This article looks at carbon trading development so far and examines the key challenges ahead in China. These past experiences—whatever from international CDM practice, or SO₂ emission trading and a domestic voluntary carbon market—have paved the solid way to build the existing ETS pilots similar to European Union Emissions Trading System (EU ETS). The investigation into China’s ETS pilots discovered some important and urgent issues such as the capsetting and deepening energy market reform.
