金融约束、代理成本假说与企业投资行为——来自中国上市公司的经验证据

Financial constraints due to the imperfection of capital market have been emphasized as an important factors determining investment by researchers recently. Beside of which, the soft budget constraints (SBC) and agency problem caused by dual property structure of enterprise system are even more important for investment in transitional China. Combing the background of aggregate investment, this paper analyzes the investment behavior and its inner mechanism of listed company in China from different views of SBC, agency cost theory and financial constraints. Based on the empirical study of 1 373 listed company, we find there is indeed some differences for SOE and non-SOE in the aspect of financial constraints even the hypothesis on nexus of cash flow and investment fails. Evidence has been found to support that principal-agency problem in the background of SBC and financial constraints can explain the investment behavior of listed company jointly, which provides another way to interpret the investment behavior of listed company in transitional country. __________ Translated from Nankai Jingji Yanjiu 南开经济研究 (Nankai Economic Studies), 2008, (1): 3–18     

政府创新投入可以促进市场创新投入吗——基于我国内地63所教育部直属高校科技创新数据的实证研究

高校是我国重要的创新研发主体,高校经费主要来源于政府和市场,这两种异质性研发创新投入关系值得关注。选取2005-2018年我国内地63所教育部直属高校科技创新数据,采用面板VAR模型和个体固定效应模型,从动态和静态两个方面对高校科技创新投入中政府创新投入与市场创新投入的关系进行实证检验。结果发现,在高校科技创新活动中,政府创新投入对市场创新投入存在积极影响,这种促进作用存在两期左右的滞后期,且只在短期内显著;从长期看,政府投入对市场投入的促进作用不显著。     

数字普惠金融对高技术制造业创新韧性的影响——基于系统GMM与门槛效应的检验

基于2011—2019年中国内地30个省份面板数据,运用系统GMM和门槛效应模型,检验数字普惠金融对高技术制造业创新韧性的影响以及消费升级和研发投入强度的门槛效应。结果表明,数字普惠金融及其覆盖广度、使用深度和数字化程度均对高技术制造业创新韧性具有显著正向影响;消费升级、研发投入强度分别在数字普惠金融对高技术制造业创新韧性的影响中表现出单一门槛效应和双重门槛效应。进一步的地区异质性研究发现,数字普惠金融仅对中西部地区高技术制造业创新韧性起到提升作用,消费升级在东部和中西部地区分别表现出双重门槛效应与单一门槛效应,研发投入强度在东部和中西部地区均表现出单一门槛效应。研究结果有助于丰富数字普惠金融应用于高技术制造业相关研究,为高技术制造业利用数字普惠金融提升创新韧性提供实践启示。     

近20年来台湾对大陆直接投资的空间格局演化

在台湾对大陆直接投资的时间序列演变与东西部差异分析的基础上,运用Moran指数及Getis-Ord Gi方法,进一步对1991年以来台商直接投资(以下简称TDI)在大陆的空间格局演化进行研究。结论表明:①TDI在大陆分布表现出明显的东西差异,同时表现出沿海向内陆地区不断扩散、转移的趋势;②TDI的空间分布存在显著的空间相关性,在大陆存在明显的空间集聚,但这一集聚趋势逐渐减弱;③TDI的空间格局存在明显"圈层结构",冷热点区域波动变化,热点区域近20年不断向北扩展,但环渤海地区至今仍未成为台商投资的热点区域。     

Decision Utility and Anticipated Discrete Emotions: An Investment Decision Model

Integrating theories and findings from various disciplines, we develop a decision utility model to explain how anticipated discrete emotions mediate investment decisions. We illustrate the model with the anticipated discrete emotions of a hypothetical Ponzi scheme investor and suggest practical measures to manage financial risks, emotionally.     

Sudden stops, banking crises and investment collapses in emerging markets

We evaluate whether financial openness leaves emerging market economies vulnerable to the adverse effects of capital reversals (“sudden stops”) on domestic investment. We investigate this claim in a broad sample of emerging markets during the period 1976–2002. If the banking sector does not experience a systemic crisis, sudden stop events fail to have a significant impact on investment. Bank crises, on the other hand, have a significant negative effect on investment even in the absence of a contemporaneous sudden stop crisis. We also find that openness to capital flows worsens the adverse impact of banking crises on investment. Our results provide statistical support for the policy view that a strong banking sector which can withstand the negative fallout of capital flight is essential for countries that open their economies to international financial flows.     

政府背景风险投资对创新的甄选与培育效果——不同区域环境视角的检验

以创业板企业数据为样本,使用Logit模型及工具变量法,研究不同区域环境下政府背景风险投资对企业创新的事前甄选与事后培育作用,并对其机制进行探讨。结果表明：①经济区域对政府背景风险投资行为影响有限,与非核心发达地区相比,金融发达地区的政府背景风险投资对企业技术创新没有表现出差异性甄选行为,但却有更好的事后培育作用,而且这种培育作用会随着地区投资环境优化而增强;②行政区域对政府背景风险投资行为影响显著,与异省投资相比,本省政府背景风险投资对技术创新的事前甄选具有显著优势,但对被投企业后续创新投入产生了一定的负面作用,这种作用会因政府背景风险投资占有董事会席位而加大。     

城市轨道交通站点周边“灰色用地”选区研究

在对我国轨道交通建设的投融资问题进行探讨的基础上,研究了城市"灰色用地"规划对轨道交通建设的适应性,指出这种动态用地规划模式可以提高土地的使用价值和利用效率,解决轨道建设投融资的部分问题,并结合苏州轨道2号线建设对轨道站点周边"灰色用地"选区方法进行了详细研究。     

Holdup in oligopsonistic labour markets - a new role for the minimum wage

We consider a labour market model of oligopsonistic wage competition and show that there is a holdup problem although workers do not have any bargaining power. When a firm invests more, it pays a higher wage in order to attract workers from competitors. Because workers participate in the returns on investment while only firms bear the costs, investment is inefficiently low. A binding minimum wage can achieve the first-best level of investment, both in the short run for a given number of firms and in the long run when the number of firms is endogenous.
