个体领导力形成因素的实证分析——以军队师团职政工领导干部为例

本文以军队师团职政工领导干部为研究对象,通过问卷调查和定量分析,初步验证:军队政工领导干部的领导力主要有16个因素形成,他们构成二阶层次结构。领导特质可作为领导力形成因素的综合表达,主要可通过三个一解因子——品德与价值观、关键领导能力、核心领导素质予以反映。同时,实证分析结果表明,领导者和非领导者对领导力形成因素的看法没有显著差别。     

欧元区成员国通胀差异成因研究

在欧元区内部,不同国家之间的通胀率存在不容忽视的差别。欧元区各经济体间究竟为什么会存在差别如此之大的通胀率呢?什么因素及在多大程度上影响了通胀率的差异?文章从巴拉萨—萨缪尔森效应、价格的收敛效应、输入性通胀、本国要素市场结构差异、本国财政政策和经济周期等六个方面,使用实证数据和面板数据回归探讨了这些问题。     

农业与非农业地租的动态均衡分析

地租是马克思主义经济学中最富争议的问题之一。马克思的地租模型是特定历史条件下的产物,相对较低的农业资本有机构成和地权流转等因素一旦发生变化,马克思地租模型的结论便需要重新审视,而且马克思地租模型缺乏对非农用地地租问题的系统分析,可以说马克思的地租模型是一个局部的、静态的均衡分析。本文在坚持劳动价值论和生产价格理论的基础上,运用动态的一般均衡分析工具,把剩余价值、资本有机构成、地权流转等变量内生化,试图建立起关于农业和非农业绝对地租与级差地租的一般分析框架。     

地区间经济互动与增长差异:一个理论分析框架

尝试将地区间经济增长差异放入一个可分析的经济学模型框架中加以理解。通过建立一个数学形式的经济增长模型,试图从地区间经济互动的角度去理解地区间经济增长之差异,从模型分析中推导出若干有意义的结论。     

Estimating gravity equation models in the presence of sample selection and heteroscedasticity

Gravity models are widely used to explain patterns of trade. However, two stylized features of trade data, sample selection and heteroscedasticity challenge the estimation of gravity models. We propose a two-step method of moments (TS-MM) estimator that deals with both issues. The Monte-Carlo experiments show that the TS-MM estimates are resistant to various combinations of sample selection and heteroscedasticity. Moreover, the TS-MM estimator performs reasonably well even when the data generating process deviates from the TS-MM assumptions. We revisit the world trade in 1990 to illustrate the usefulness of the proposed model, with emphasis on the identification of the extensive margin of trade.     

服务型制造项目治理的影响因素及其作用路径

在网络结构和治理模式影响服务型制造项目治理绩效的相关研究成果的基础上,加入中间变量——治理能力。运用结构方程模型方法,利用调查问卷数据进一步分析了网络结构、治理模式、治理能力与治理绩效之间的影响关系,构建了服务型制造项目治理影响路径图。结果表明:网络结构和治理模式对项目治理能力都有显著的直接影响;治理能力对项目治理绩效有直接的、显著的正向影响;网络结构与治理模式互相影响。     

股权结构和公司绩效的联立实证研究

关于股权结构与公司绩效的研究,传统方法主要以不考虑内生性的OLS实证研究为主,近年来国内学者才逐渐运用联立方程模型研究内生性下的股权结构与公司绩效关系。股权结构具有内生性,但无论考虑内生性与否,股权集中度、股权制衡度与公司绩效之间都呈显著正向线性关系;与股权制衡度相比,股权集中度对公司绩效的影响更加显著。今后应进一步完善外部监督等公司治理机制,发挥外部股东的股权制衡作用,进而减少大股东侵害行为,提高公司价值。     

Key impact factors of visitors’ environmentally responsible behaviour: personality traits or interpretive services? A case study of Beijing’s Yuyuantan Urban Park,China

The environmentally responsible behaviour (ERB) facilitates the sustainability of tourism destinations. This study aims to identify the key impact factors to promote visitors’ ERB in urban park and examine the impact mechanism. A total of 567 visitors were surveyed in Beijing’s Yuyuantan Urban Park. Structural equation modelling results indicate that personality traits are the most important factors that affect visitors’ ERB, while the effect of how satisfaction with interpretive services plays upon visitors’ ERB using place attachment as a mediator. Openness traits positively affect satisfaction with experiential services and general behaviour. Additionally, implications in urban park management are provided.     

The effect of external supply knowledge acquisition,development activities and organizational status on the supply performance of SMEs

Given the increasingly strategic role of external resources, acquiring knowledge about current suppliers and the broader supply market is an important and demanding task for the purchasing and supply management (PSM) function of a firm. Performance-improvement-oriented application of external supply knowledge present further challenges for the function. To examine this, we draw on the knowledge-based view and develop a hypothesized model in which supply knowledge acquisition drives PSM exploration and exploitation orientations which in turn mediate the organizational status of PSM function in terms of supply performance. We test the model on an SME-focused and survey-based dataset, using structural equation modelling. Our results indicate that an exploitative orientation is associated with knowledge gained from the supply base, whereas an explorative orientation is predominantly associated with supply market knowledge and less with supply base knowledge, suggesting natural pairings. The findings also show how an exploitative development orientation mediates the positive association of the PSM function's organizational status with supply performance. Driven by supply base knowledge, a status-empowered exploitative PSM orientation may suppress supply market based explorative orientation in resource-scarce SMEs, thus appearing to serve as the sole path to supply performance. Our research contributes by pointing out the significance of the knowledge-resource, and the knowledge-based view, in understanding performance in PSM.     

特许权价值、最优关闭策略和存款保险定价

随着存款保险制度的推出以及金融机构退出机制的完善,国家声誉将逐渐退出银行无形资本。在激励相容的金融监管趋势下,特许权价值等市场约束力量会显著影响到商业银行的风险承担。在此逻辑基础上,以我国16家上市商业银行为研究对象,一方面探讨特许权价值影响下不同产权结构的商业银行的最优救助机制,另一方面通过最优救助临界指标,利用银行重组模型,推导合理的存款保险风险差别费率。
