产业结构调整的汇率驱动路径:价格穿越模型的解释

汇率作为宏观经济调节变量,在受到其它经济条件或经济因素影响的同时,其变动对国民经济也有着广泛而复杂的作用。通过对中国汇率制度历史演进的分析,可以发现人民币汇率的变动始终与中国产业结构的调整息息相关。文章以价格这一中间变量作为动力因素,建立价格穿越模型,分析汇率变动引起产业结构调整的传导路径与作用机理。     

投资者参与、企业内在价值与IPO抑价——基于中国A股市场的经验证据

本文以中国A股市场为背景,以2009～2010年沪深两市通过IPO募集股权资本的上市公司为样本,探讨了投资者参与程度、企业内在价值与IPO抑价之间的关系。研究发现,在诸多影响因素中,以市盈率衡量的企业内在价值与IPO抑价负相关;以中签率和换手率衡量的投资者参与程度,与IPO抑价正相关。较低的中签率和较高的换手率,代表更高的投资者参与热情,通常会导致更高的IPO抑价。此外,诸如IPO规模和行业特征等其他因素也会对IPO抑价产生影响。     

上市公司可持续增长率偏差的实证分析

按照可持续增长率进行发展,要求企业全面权衡各方面的契约关系,以稳定的契约结构获取企业的长期增长。但是在现实中由于各种原因,企业不可能完全按照可持续增长率进行增长,出现了可持续增长率偏差。本文通过对我国A股市场的上市公司在1997-2005年的可持续增长情况进行分析,研究了我国上市公司可持续增长率偏差的主要影响因素及其对未来经营业绩的影响。研究结果表明：影响可持续增长率偏差的主要因素包括资产运作效率变动、资本结构的调整、外部权益融资和销售净利率的变化,鼓励政策对企业的可持续增长率偏差并没有显著作用。另外本文还验证了较高的可持续增长率偏差对后期（5年）的业绩提高具有消极作用。     

The China model view is factually false

ABSTRACT

Using a cross-regional analysis of China, this article shows that the China model view is factually false and the universal model view is factually true. It is the marketization and development of non-state sectors, rather than the strong power of government and the state sector, that have driven the Chinese economy to grow fast and to be increasingly innovative. If China wants to sustain its economic performance, it must stay on the way to continuing marketization. Otherwise, China will fall into stagnation.     

On the global supply of basic research

In a two-country Schumpeterian growth model, we study the incentives for basic research investments by governments in a globalized world. A country׳s basic research investments increase with the country׳s level of human capital and decline with its own market size. This may explain why some smaller countries invest so much in basic research. Compared with the optimal investments achievable when countries coordinate their basic research policies, a single country may over-invest in basic research. However, the total amount of decentralized basic research investments is always below the socially optimal investment level, which justifies policy coordination in this area.     

Services as drivers of economic growth. Is there an opportunity for Latin America countries?

ABSTRACT

Considering the recent improvements in services innovation and productivity performance, the aim of the article is to analyze if they can act as a new growth driver for Latin American countries. For that, we review the literature on services and structural change in two stages. First, we apply a bibliometric methodology to identify the main trends in literature. Second, we analyze in-depth a smaller set of papers in order to extract the main lessons regarding three aspects of our question: (i) services and productivity growth, (ii) new opportunities for innovation in services and (iii) relation between services and manufacturing through servitization process. The results show that productivity and innovation growth in services are concentrated in only a few branches. Besides this, services performance depends on their links with manufacturing activities. We conclude that the current Latin American servitization process clausure opportunities for developing instead of opening them.     

青海省普惠金融发展对经济增长影响研究

为研究青海省普惠金融发展对经济的影响,本研究结合青海省2015-2020年的统计资料来分析普惠金融的发展对经济增长的影响,分别从国内生产总值、三次工业增加值所占的比重来衡量青海省普惠金融在经济中的发展现状;用金融机构的存款余额及其贷款余额、财政厅专项资金的投入情况来衡量青海省普惠金融的发展现状。得出结论为:普惠金融的发展对经济增速具有正向作用。     

论生态经济及其发展

广义的生态经济,是指地球生态圈内人类经济活动的总和,它涉及生态、经济、社会三大系统层面,是人类经济活动与生命支持系统协调可持续发展的经济模式。狭义的生态经济,是指人类为加强生态保护而采取的经济行为的总和。随着全球可持续发展战略的实施,生态经济以生态产业为标志、以生态产业园区的形成作为方向,正在进入快速成长时期。同时,也正向着产业生态化方向发展,即将生态园区的概念加以拓广,向前延伸到绿色原料、能源及工业无机环境的构建,向后延伸到消费领域。因此,发展生态经济应该注重生态营销策略研究,从而塑造企业的理念与形象,培育企业的品牌、传播企业文化、倡导绿色消费理念。
