跨国公司对华直接投资区位选择战略比较研究

区位因素是影响跨国公司制定对外直接投资战略的重要因素之一。本文以日本、韩国、美国、港澳等国家和地区为代表,分析了跨国公司对华直接投资的动机及区位选择战略,在此基础上提出加入WTO之后中国企业海外直接投资的区位选择战略。     

我国原产地规则存在的问题与对策研究

原产地规则(Rules of Origin,ROOs)是国际贸易中的一项重要规则和各国海关管理的一项重要制度,它涉及到每一国家和地区的经济贸易利益,因此已成为各国对外贸易政策的重要组成部分。然而当美国、欧盟等发达国家、区域集团把原产地规则作为一种“灰色”的政策工具灵活自如地运用时,中国对原产地规则的运用却仍停留在最惠国和普通两栏关税税率的计征和进口国别统计上。由此引发了大量的他国歧视性地使用原产地规则的纠纷。中国制定和运用相对完善的原产地规则以抵御贸易保护主义、维护自身利益已迫在眉睫。

自适应聚类视角下学科领域主题分析——以物流学科为例

基于改进关键词重要性和近邻传播聚类算法,提出了一种学科领域主题分析方法,通过词频分析法和作者潜意识行为计算高频关键词权重,借助共词分析和Ochiai系数构建带权重高频关键词相似性矩阵,利用近邻传播聚类算法对学科领域主题进行自适应提取与分析。以CSSCI收录的2015—2019年物流学科领域期刊论文为研究对象,借助新方法对其进行主题分析,研究结果表明:高重要性的关键词不一定是核心主题,核心主题与同一簇内其它成员关键词最为相似。与此同时,近五年物流学科存在“降本增效”“区域物流一体化”“现代物流技术研究与创新”“物流体制改革与产业转型升级”“农村物流与农产品物流”“电子商务与跨境电商”“可持续发展理念”等七大热门主题。     

平价上网光伏发电项目经济性评价、影响因素及对策

太阳能光伏发电在我国经历了快速的推广应用,虽因享受高额财政补贴而备受争议,但太阳能光伏发电逐步摆脱对财政补贴的依赖,已经达到了平价上网的条件。本文回顾了我国光伏发电上网电价下降的历程,探讨了促进上网电价逐步下降的驱动力。建立以内部收益率(IRR)为平价上网光伏发电项目经济性评价的模型,分析了影响平价上网太阳能光伏发电项目经济性评价的“弃光”严重、非技术成本高企、补贴拖欠等因素,通过算例分析计算了其影响程度,并对解决这些障碍因素从政府和企业两方面提出了对策与建议。     

汽轮机的运行和故障分析

企业的经营生产离不开电力的供应,而现阶段我国的电力供应依靠发电厂供电,通过汽轮机等一系列机械设备来产生电能。就目前的情形来看,为了保证我国更好地发展,还需要加强对电力设备的保障,而汽轮机则是其中的重要环节。     

Does the social security fund help non-financial enterprises to transform from the virtual to the real?

At its 19th National Congress, the Communist Party of China vowed to “strengthen the financial sector’s ability to serve the real economy.” However, many studies provide evidence of the opposite trend, a problematic “transition from the real to the virtual,” among Chinese enterprises. Meanwhile, the investment efficiency of China’s Social Security Fund (SSF), a public fund, attracts much attention. In this context, we use A-share listed companies in China from 2009 to 2018 to study the relationship between holding by the SSF and enterprise financialization. We find that SSF holding significantly inhibits financialization and that this effect is non-linear. Mechanism analysis indicates that SSF holding suppresses enterprises’ financialization mainly by improving their governance. Moreover, SSF holding more strongly inhibits small-scale (vs. large-scale), state-owned (vs. non-state-owned), and non-eastern (vs. eastern) enterprises in China. Furthermore, SSF holding can alleviate corporate value impairment caused by financialization. The conclusions enrich theoretical research and provide empirical evidence that may help regulatory authorities to guide investment by enterprises and prevent financial risks.     

CEO power and annual report reading difficulty

We examine the impact of CEO power on reading difficulty of corporate annual reports. We find that CEO power is positively related to reading difficulty, implying that annual reports of corporations with powerful CEOs are difficult to read and understand. More importantly, we find that the relation between CEO power and reading difficulty is moderated by earnings performance or corporate governance. Additional findings suggest that this relation becomes stronger for firms with lower financial reporting quality or for CEOs with shorter tenure. Our study not only joins the debate on the consequences of powerful CEOs but also uncovers several factors that moderate the relation between CEO power and annual report reading difficulty.     

Regional, national, and spatially explicit scenarios of demographic and economic change based on SRES

We report here spatially explicit scenario interpretations for population and economic activity (GDP) for the time period 1990 to 2100 based on three scenarios (A2, B1, and B2) from the IPCC Special Report on Emissions Scenarios (SRES). At the highest degree of spatial detail, the scenario indicators are calculated at a 0.5 by 0.5 degree resolution. All three scenarios follow the qualitative scenario characteristics, as outlined in the original SRES scenarios. Two scenarios (B1 and B2) also follow (with minor adjustments due to scenario improvements) the original SRES quantifications at the level of 4 and 11 world regions respectively. The quantification of the original SRES A2 scenario has been revised to reflect recent changing perceptions on the demographic outlook of world population growth. In this revised “high population growth” scenario, A2r world population reaches some 12 billion by 2100 (as opposed to some 15 billion in the original SRES A2 scenario) and is characterized by a “delayed fertility transition” that is also mirrored in a delayed (economic) development catch-up, resulting in an initially stagnating and subsequently only very slow reduction in income disparities. The spatially explicit scenario interpretation proceeds via two steps. Through a combination of decomposition and optimization methods, world regional scenario results are first disaggregated to the level of 185 countries. In a subsequent second step, national results are further disaggregated to a grid cell level, taking urbanization and regional (rural–urban) income disparities explicitly into account. A distinguishing feature of the spatially explicit scenario results reported here is that both methodologies, as well as numerical assumptions underlying the “downscaling” exercise, are scenario-dependent, leading to distinctly different spatial patterns of population and economic activities across the three scenarios examined.
