How does employee development affect turnover intention? Exploring alternative relationships

This study explores alternative relationships between perceived investment in employee development (PIED) and turnover intention by including affective commitment, perceived internal employability, and perceived external employability as potential mediators. Data were collected through a structured survey from 337 employees working in two large companies in Italy. The factorial validity and dimensionality of the latent constructs studied were evaluated in a confirmatory factor analysis framework, and the mediation hypotheses were tested in a full structural equation model. Results show that the overall effect of PIED on turnover intention is negative and almost fully mediated by external employability and affective commitment, whereas the path through internal employability is not supported. More specifically, PIED increases commitment, which in turn limits the likelihood of turnover. In addition, although perceived external employability is positively associated with turnover intention, PIED seems to reduce this effect by negatively affecting employee perceptions of their marketability in the labour market. The study supports the assumptions of social exchange theory in explaining turnover behaviour as a consequence of employee development support. Contextually, it questions the existence of the employability paradox because it does not reveal either a retention path via perceived internal employability or a turnover risk via perceived external employability.     

An emerging market multinational Company's internationalization: From original equipment manufacturer to global brand leader

We examine an emerging market multinational company's (EMNC's) transformation from an original equipment manufacturer (OEM) to an original brand manufacturer (OBM) and global leader. Our longitudinal study of Hisense—China's largest TV company (and the world's third largest) spans three decades and involves detailed interviews with over 50 executives. We study how the company's global value chain network evolved, how it reconfigured its organization, upgraded its capabilities, and enhanced its brand reputation. We develop propositions that may contribute to improved explanations for an EMNC's internationalization sequence, development of competitive advantages, overseas management practices, and brand building.     

Model-free portfolio theory: A rough path approach

Based on a rough path foundation, we develop a model-free approach to stochastic portfolio theory (SPT). Our approach allows to handle significantly more general portfolios compared to previous model-free approaches based on Föllmer integration. Without the assumption of any underlying probabilistic model, we prove a pathwise formula for the relative wealth process, which reduces in the special case of functionally generated portfolios to a pathwise version of the so-called master formula of classical SPT. We show that the appropriately scaled asymptotic growth rate of a far reaching generalization of Cover's universal portfolio based on controlled paths coincides with that of the best retrospectively chosen portfolio within this class. We provide several novel results concerning rough integration, and highlight the advantages of the rough path approach by showing that (nonfunctionally generated) log-optimal portfolios in an ergodic Itô diffusion setting have the same asymptotic growth rate as Cover's universal portfolio and the best retrospectively chosen one.

建设抚—哈合作开发区的设想

抚远县和一江之隔的哈巴罗夫斯克市及其周围地区,以其优越的地缘优势、资源优势和互补性,具有发展双边(多边)经济技术合作的广阔前景。建设抚哈合作开发区,不仅有利于振兴当地经济,而且可作为参与东北亚国际分工与合作的窗口,通过外参内联,实现由边疆到内地,由双边到多边的多种形式的经贸合作,带动和促进两国内地经济的发展。     

市场培育视角下科技协同创新模式的构建与完善

科技创新是创新驱动发展战略的核心,创新驱动发展战略的实施需要先进的科技创新模式支撑。由于目前我国科技创新市场发育还不完善,科技创新成果转化率、原创性以及经济增长效应均较低,尤其是现有科技创新模式忽视创新成果的原创性及转化率,且与国家发展战略的契合度不高,有效科技创新不足成为制约创新驱动发展战略实施的主要因素之一。从科技市场培育角度来看,应基于创新驱动发展战略理念,构建以企业、高校和科研院所、政府为主体的科技协同创新模式,转变创新主体观念和行为,完善创新成果交易市场,强化创新人才培养和管理,为创新驱动发展战略的顺利实施提供充分有力的科技创新支撑。     

区域经济协调发展与财税政策研究

遏制煤矿事故构建和谐社会

近几年,煤炭企业的伤亡事故频频发生,成为建设和谐社会不能承受之重。我国煤矿事故多发的直接原因是利益的驱动,煤矿事故多发的深层次原因是经济增长方式落后,旧的生产模式遗留的恶果。要以科学发展观指导,建立和完善煤矿安全生产指标及控制体系,提高科学技术水平。遏制煤矿事故,促进社会主义和谐。     

成渝地区双城经济圈协同创新发展现状与对策

成渝地区双城经济圈的建设对于当前形成国内大循环的经济发展新格局具有重要的战略意义。本文以成渝地区制造业与生产性服务业协同集聚为研究对象,以城市层面的全要素生产率作为城市高质量发展的衡量指标,利用成渝地区16个城市2005-2018年数据,构建动态面板模型,采用系统GMM的方法实证检验成渝地区双城经济圈制造业与生产性服务业协同集聚对成渝地区城市全要素生产率的影响,并基于DEA-Malmquist的方法对城市全要素生产率进行分解,通过对产业协同集聚和全要素生产率水平的测算构建模型,并实证检验了产业协同集聚对生产率影响的效果,提出通过平台共建、政策共通、市场共融以及人才共用等方面建立一体化协同发展体系推动成渝地区双城经济圈协同创新发展。     

大城市边缘区土地利用变化与社会经济发展关系分析——以北京市平谷区为例

大城市边缘区是城市化最敏感、变化最大、最迅速的地区,也是土地利用变化最显著的地区,研究大城市边缘区土地利用变化时空过程及其驱动机制,对实现大城市自身可持续发展具有重要意义。该文采用数理统计与综合分析方法,对北京市平谷区土地利用动态变化及其与GDP、产业结构、消费结构、城镇化以及人口等社会经济发展因素的关系进行了分析。研究结果表明:1996~2004年,平谷区农用地面积持续减少,其中耕地减少较多,园地增长速度较快,林地略有减少。建设用地持续增加,其中交通用地增长速度最快。平谷区的土地利用变化与经济增长、产业升级、城镇化发展、消费结构变化以及人口增长具有显著的相关性,社会经济发展是土地利用变化的主要驱动因素。节约集约土地,提高土地利用效率,调整土地利用结构,促进产业优化升级,保障服务首都北京功能和平谷区域社会经济发展成为平谷区土地利用的必然要求。
