高管性别差异对上市公司投资行为的影响分析

在现在这个激烈竞争的时代,高管对上市公司投资行为的影响越来越大。高管是公司投资决策的制定者和执行者,但是已有关于高管特征的研究仅涉及年龄、教育、任期、职业背景、社会经济地位等几个方面,较少涉及高管性别差异对上市公司投资行为的影响。而高管性别差异又可能是影响上市公司投资行为的重要因素之一,所以关于高管性别差异对上市公司投资行为的影响分析是必不可少的。本文从固定资产投资、无形资产投资、长期股权投资这三个方面进行考察,计算、分析由于高管性别差异对这三个方面投资比率的影响。从而得出优秀的女性高管和男性高管一样,可以为上市公司做出正确的、适当的投资决策。所以在任用高管时不应有性别歧视,应提高女性在上市公司高管中的比例,从而有利于高管做出对上市公司有利的投资决策、投资行为。

欧盟公共与私营电子采购标准化要求异同初探

电子采购的兴起,逐渐革新了传统的采购模式,大大地提高了效率,节约了成本。欧盟是电子采购制度建设较早的地区之一,且渗透到私营和公共采购领域。为了提高公共与私营电子采购之间的兼容性,2005年2月欧洲标准化委员会（CEN）正式发布了《欧盟电子采购标准化要求和差距分析》（CWA15236）。文章将根据《欧盟电子采购标准化要求和差距分析》（cwA15236）,以现有的法律、标准规范和技术为基础,分析欧盟公共与私营电子采购在法律层面、程序层面和技术层面的主要异同点,同时提出了相关建议。     

Formation of entrepreneurial intentions in a regional context

Research on the impact of the regional environment in the very early phase of the business start-up process is currently limited. This paper contributes to the literature by analysing the influence of regional factors on the formation of entrepreneurial intentions within the theory of planned behaviour (TPB) framework. The rationale is based on the previous literature which posits that regional conditions have implications for individual perceptions, which, in turn, constitute the foundation of the three antecedents of intention in the TPB model: attitudes, subjective norm and perceived behavioural control. A multilevel analysis based on a random sample of 834 Finnish working-age individuals, combined with the official national statistics at the municipality level supports the proposition that regional conditions have an indirect impact on the intent to become an entrepreneur. The population density, the level of education, income and wealth and the rate of public and manufacturing sector employment of a region are found to moderate the individual formation of entrepreneurial intentions. This study supports further development of the theoretical understanding of entrepreneurial intentions by demonstrating that regional characteristics are important moderating influences in the TPB model.     

Entrepreneurship and path dependency in regional development

This paper describes a case study of path-dependent industrial development in a specialized medium-sized region characterized by a specialized high-tech industry cluster, located near Norway's capital, Oslo. The case study examines the path-dependent process of new industry arising from technology-related industries through three main branching mechanisms: entrepreneurship, mobility, and social networks. More particularly, the study explores the extent to which regional branching mechanisms relate to different path-dependent processes of path extension, path renewal, or path creation. The case study of industrial development in a medium-sized region that critically examines the concepts of path dependence, and argues that specialized medium-sized regions follow different path processes from core regions due to regional branching that does not happen automatically but instead may require policy action and external investment to avoid stagnation or negative lock-in.

Measuring China’s domestic production networks through Trade in Value-added perspectives

Evaluating the role and performance of China's participation in Global value chains (GVCs) has been a hot policy and research issue in recent years. However, most GVCs-related literature about China focuses on country-to-country relations; less attention has been paid to China's domestic value chains (DVCs). GVCs should have their domestic foundations since strong linkages across domestic firms and regions can improve productivity through gains from specialization, which make domestic industries more competitive in GVCs in turn. This paper applies the so-called Trade in Value-added (TiVA) concept and the decomposition of domestic-regional trade in TiVA terms to re-measure the inter-industrial and interregional linkages in China's DVCs. We show that TiVA-based measures can significantly enrich our understanding on both the structure change of China's regional economy and the position and participation degree of Chinese regions in DVCs.     

世界遗产保护与区域旅游可持续发展关系的《周易》解读

<周易>是中华民族古代思想的结晶,是中国文化的核心和灵魂.其中"易"的思想、"阴阳平衡"论,"天人合一"观,对于正确处理世界遗产保护和区域旅游可持续发展的关系具有重要指导意义.目前,世界遗产保护和区域旅游可持续发展存在着阴阳失衡、忽略了易的思想、违背天人合一观等三个问题.我们应从<周易>哲学思想得到启示,立足长远.采取有效措施,保护世界遗产,实现区域旅游可持续发展.     

The impact of production offshoring on the skill composition of manufacturing firms: evidence from Italy

In this work we explore how the international outsourcing of production impacts the skill composition of employment within Italian manufacturing firms. In particular, our aim is to assess whether the choice to offshore production activities to cheap‐labour countries implies a bias in the employment of skilled workers relative to unskilled ones.

Using a balanced panel of firms covering the period 1995–2003, we set up a counterfactual analysis in which, by using a difference‐in‐differences propensity score matching estimator, we compare the dynamics of skill demand for treated and control firms while addressing the possible problem of selection bias.

Our results identify a ‘potential’ skill bias effect of production offshoring. In particular, we find that treated firms tend to show an upward shift in the skill ratio with respect to the counterfactual sample, but coefficients are not significantly different from zero. When we look at the elements of the skill ratio separately, we find that the skill bias is driven by a fall in the employment of production workers (blue collars), rather than by the increase in the employment of non‐production workers (white collars), thus providing further evidence on the unskilled labour‐saving nature of international outsourcing.
