普惠金融对投资效率的非线性效应分析

基于湖南省2008年-2013年87个县（市）的面板数据,利用面板平滑转换模型（PSTR）,实证研究了普惠金融等因素对投资效率的非线性效应。研究发现,普惠金融发展对投资效率具有显著的非线性效应,存在明显的门限特征。在门限值前后,普惠金融发展对投资效率的影响由降低转变为提高。预算收入水平、经济发展方式、产业结构等因素对投资效率的影响因受到普惠金融发展的制约,在门限值前后也都表现出截然相反的效应;经济发展对投资效率的影响始终是正向的,只是在门限值之后,经济发展提高投资效率的速度会变缓。     

创业企业创新投入、高管过度自信对企业绩效的影响

基于2012-2015年创业板上市公司数据,实证检验了创业企业创新投入、高管过度自信对企业绩效的影响。研究发现：①企业创新投入与企业绩效呈显著倒U型关系,即随着创新投入的增加,企业绩效呈现边际效应递减规律;②高管过度自信与企业绩效显著负相关,即高管过度自信的自我意识对企业绩效具有显著负向影响;③高管过度自信及企业创新投入之间存在交互效应,显著影响企业绩效。     

The relationship between globalization and insurance activities: A panel data analysis

This study applies a Bootstrap Panel Granger causality test to investigate whether there is causal relationship between globalization and insurance activity. We examine data from sigma reports of Swiss Reinsurance Company for 8 Eastern Asian countries over the period of 1979–2008. Empirically, results for one-way Granger causality show the influence of total insurance activity, life insurance activity, and non-life insurance activity on globalization only in Korea. However, there is strong causality from globalization to insurance activity for Thailand, Malaysia, and the Philippines. In our research, the results show that the causality between globalization and insurance activity varies across countries with different conditions. The findings of this study could provide important policy implications for the 8 Eastern Asian countries under study, namely India, Indonesia, Japan, Malaysia, the Philippines, Singapore, South Korea, and Thailand.     

要素禀赋结构变迁中的农业适度规模经营研究

要素禀赋结构对农业适度规模经营有着直接的影响,构建以土地、劳动力和资本为变量的农业要素禀赋结构模型,可以揭示要素禀赋结构变迁中农业适度规模经营的动态机理以及政府过度干预要素市场行为对农业适度规模经营的影响。农业适度规模经营是在既有的要素禀赋结构下实现土地、劳动力和资本等要素的合理配置,并随着要素禀赋结构的升级而变迁。政府过度干预要素市场,将会造成农业经营规模偏离农业要素禀赋结构,政府促进农业适度规模经营的政策必须建立在符合要素禀赋结构的前提上。当前,为促进我国农业适度规模经营,政府的着力点应该是提供必要的基础设施,努力打造开放、自由和竞争的市场环境,大力培育农业生产单位的自生能力,并建立和完善配套的保险制度和补偿机制以降低农业规模经营风险。     

Antecedents of patent value using exchange option models: Evidence from a panel data analysis

This paper examines the patent impact factor by an empirical study using panel data. To investigate the impact factor of patent value, this study conducts a sensitivity analysis of a patent evaluation model within the framework of a real option, while considering the uncertainties associated with both patent counts and the amount of R&D per patent, and develops an empirical analysis method for examining the impact factor of a patent using an unbalanced two-way fixed effects model. The empirical results indicate that the increase of patent value accords with the increase in the patent counts, volatility and patent lifetime. Although patent value declines with the amount of R&D per patent, the impact is not significant. However, reducing cost, raising patent counts and enhancing innovation efficiency offer a feasible method for a firm to increase patent value.

美、日、中三国废钢利用现状研究

通过对美、日、中三国的长期历史粗钢产量和社会采购废钢量等数据进行分析,探讨各自钢产量的变化情况与废钢利用发展之间的关系。利用废钢净出口量、废钢指数与废钢单耗等指标衡量三个国家废钢资源的充足程度与利用水平,并比较分析三个国家废钢利用的不同之处,从中找出我国与发达国家在废钢利用方面的优势与不足。     

工业制成品国际竞争力决定因素的实证分析

利用1992—2009年的多国面板数据对工业制成品国际竞争力的决定因素进行了实证分析,显著的影响因素包括：FDI、资本深化程度、名义汇率、进口技术水平、本国的技术创新能力等。我国应进一步吸引优质的FDI,促进产业结构升级;不断提高资本深化程度,提升资本技术密集型制成品出口的国际竞争力;扩大进口,尤其是高技术产品进口,通过获得技术溢出来提高自身的国际竞争力;加大研发投入,提高自身的学习、吸收和创新能力。     

IS THERE AN ASYMMETRIC BEHAVIOUR IN AFRICAN INFLATION? A NON‐LINEAR APPROACH

In this paper we test the inflation persistence hypothesis as well as model the long‐run behaviour of inflation rates in a pool of African countries using a non‐linear framework. In order to do so, we rely on unit root tests applied to non‐linear models and fractional integration. The results show that the hypothesis of inflation persistence does not hold empirically for most of the countries. In addition, the estimated models (logistic smooth transition autoregressions) are stable in the sense that the variable tends to remain in the regime (low inflation or high inflation) once reached, and changes between regimes are only achieved after a shock. The results also indicate that the effects of the shocks on inflation tend to die out; exogenous factors, i.e. supply shocks and inertia may be causing this outcome, as they play a substantial role in the determination of the inflation rates for our selected African countries.
