Intra-industry diversification effects under firm-specific contingencies on the demand side

How do firm-specific, demand-related factors influence the relationship between intra-industry diversification (IID) and performance? Recent findings regarding the performance effects of IID depict a complex picture with curvilinear relationships and several contingencies. However, firm-specific contingencies on the demand side have remained unexplored. We analyze how IID relates to firm performance (market share) in the German automotive industry using panel data between 1999 and 2008. We specifically focus on a firm's high-quality brand image as a demand-side contingency. We find support for our hypotheses of complex curvilinear relationships as well as for moderating effects of brand quality. Our results have significant theoretical implications for the IID literature.

区域多元化抑或产品多元化?制度环境约束下民营企业核心能力构建与成长战略选择

在文献与理论研究的基础上,构建了制度环境、核心能力与企业成长战略选择之间关系的概念模型,并提出了相关假设。然后,以中国民营上市公司2007-2014年数据为对象进行实证检验,结果发现:市场化程度更高的区域,民营企业倾向于构建"行业专家"型核心能力,进而倾向于选择"做强"的区域多元化战略;市场化程度相对较低的区域,民营企业更多倾向于构建"社会资本"型核心能力,进而会选择"做大"的产品多元化战略。上述发现为企业成长与多元化战略理论补充了新的内容。     

原产地多元化视角下的地方产业集群升级研究

地方产业集群升级是区域经济发展的重要研究主题,由于中国特别是东部地区产业集群具有"天生全球化"特质,基于价值链的集群升级理论在适用性上存在局限。本文以原产地多元化为切入点,依据产业集群嵌入全球价值链的程度,对其通过原产地多元化实现升级的途径进行探讨,并结合案例分析加以验证。进而提出基于原产地多元化实现地方产业集群升级的主要内容和政策建议,以期为现实的产业集群发展和区域经济政策制定提供启示。     

近五年陕西省中小学教师培训多元化需求分析调查及解决策略研究

通过对自2009年以来近五年我国中小学教师专业培训需求研究成果进行分析和整理,分别从培训需求政策、培训动机需求、课程需求、模式需求等方面进行分析,最后提出解决培训中出现的问题和策略,旨在为教育行政部门提供可借鉴的参考。     

电子商务市场产品多元化战略的销售绩效及驱动因素研究

结合电子商务市场特征,从理论方面分析电子商务市场产品多元化战略的驱动因素及其销售绩效,利用正则表达式等数据挖掘技术形成电子商务市场的面板数据库,并对相关研究假设进行实证检验。结果表明：在电子商务市场上,产品多元化战略与企业销售绩效正相关,而市场同质化竞争程度与产品多元化战略负相关,企业经营时间、顾客好评率抑制了企业对产品多元化战略的选择。研究结论对于电子商务市场的企业产品多元化战略选择具有重要参考意义。     

失地农户生计策略多样化研究

利用九江和襄阳两地的失地农户调查数据,刻画失地农户生计策略多样化特征;并利用广义线性模型和广义线性混合模型,分析生计资本对失地农户生计多样化的影响。主要研究结论包括：1）失地前后农户的生计多样化与收入水平、兼业程度和劳动力流动具有某种关联;2）失地农户实施生计多样化的能力依赖于一定的生计资本,生计资本的提高有助于扩展失地农户实施生计多样化的能力;3）生计多样化虽然是失地农户发展生计的重要途径,但当生计资本超过某个临界点后农户不再将生计多样化作为其最优的选择。

Expanding and Diversifying South Mediterranean Exports through Trade Facilitation

This article explores whether trade facilitation – i.e. improved and simplified trade procedures – could be an important part of the reform agenda of the Barcelona Process. Adopting a Southern perspective by focusing on exports to the European Union (EU) from non‐EU Mediterranean countries, it tests whether the efficiency of trade procedures affects (i) bilateral volumes of exports and (ii) the number of products exported. The findings suggest that trade facilitation could lead to substantially increased export volumes and export diversification.     

The multicriteria selection of products in technological diversification strategies: an application to the Spanish automotive industry based on AHP

The economic recession, the dynamism and complexity of the markets and the generalised globalisation of the world economy have forced many companies to rethink and reorganise their industrial strategies. Through identifying and taking advantage of the key technologies of a company, this work presents a new and original methodology for dealing with a general technological diversification process. The methodology, which includes an innovative cognitive perspective and its corresponding decisional tool (decision support system) has been used to select the best product in a process of technological diversification that, along with the key technologies, identifies the sub-levels consonant to the sub-technologies and applications to sectors and products. The multicriteria selection tool employed in the proposed methodology, based on the analytic hierarchy process, allows the integration of multiple scenarios, actors and criteria, both tangible and intangible. The methodology has been applied to a case study in the Spanish automotive auxiliary sector.
