Managing distance in international purchasing and supply: a systematic review of literature from the resource-based view perspective

The aim of this research is to find out how the extant literature on international purchasing and supply management (PSM) covers the elements of capability from the perspective of distance. A priori, we form a framework of capability driving elements and conclude that distance—in its multiple dimensions—is the fundamental management aspect in international PSM. Equipped with analytical frameworks and a bottom–up process for identifying emergent themes, a systematic literature review was conducted on a representative sample of scholarly literature on international PSM, using the NVivo analysis software and a data display as tools. We identify several capability relevant themes from the literature, and provide a distance-based a posteriori conceptualisation of international PSM, founded in the information processing theory, with the source-user, user-user and source-source distance types driving the information processing requirements, and loading avoidance, policy-based and enhancement mechanisms determining the information processing capacity.     

粤港澳大湾区城市技术创新能力时空演化及影响因素研究——来自空间、门限面板数据模型的实证检验

为促进城市间协同融合发展，采用极差、变异系数、基尼系数和ESDA等方法考察粤港澳大湾区城市技术创新能力的时空演化特征及空间关联模式，并通过SPDM模型剖析影响城市技术创新能力的关键因素，结合门限面板模型进一步探讨在经济发展水平门限效应下，核心创新要素对城市技术创新能力的影响。结果显示：①城市技术创新能力总体呈上升趋势，2014年后增速加快，各城市技术创新能力均衡发展；②城市技术创新能力“中心—外围”特征明显，“中心”城市位于区域东南部沿珠江口东岸地带，空间关联模式主要表现为H-H型和L-L型；③人力资本、研发经费投入对城市技术创新能力具有显著促进作用，但人力资本的溢出效应显著为负，研发经费投入的负向溢出效应不明显；④在经济发展水平的单一门限效应下，人力资本对城市技术创新能力的影响先升后降，研发经费投入对城市技术创新能力的促进作用随着城市经济发展水平越过门槛值而不再显著。     

信贷内生扩张能力、投资外生收益冲击与价格波动——我国投资与通胀关系的一个新的解释视角

本文从一个新的视角--信贷内生扩张能力和投资外生收益冲击,对我国近些年来的投资与通胀的关系进行了解释.具体分析过程是先建立一个信贷内生扩张约束条件下的厂商长期投资动态最优化模型,并给出一个有关投资外生收益对价格影响的命题.在此基础上,我们以中国为对象,对命题成立的三个条件进行了实证检验,并对其中两个关键条件成立的背后动因进行了分析,且给出了长期增长与政策含义.

Motivation matters: Corporate scope and competition in complementary product markets

Research summary : We argue that a pure capabilities‐based view does not accurately explain the competitive dynamics of increasingly common settings in which firms act as both complementors and competitors. We propose that the Awareness‐Motivation‐Capability framework is more appropriate for these settings. We derive predictions from both a pure capabilities view and the AMC framework, and test those predictions in the U.S. auto leasing market, in which the leasing subsidiaries of car manufacturers directly compete with the same independent lessors who provide complements to the manufacturers. Although our results are consistent with capabilities playing an important role, motivation appears to be a critical factor explaining the competitive dynamics of the market. Managerial summary : Firms that compete with business units owned by larger corporate parents face additional considerations. Such subsidiary competitors can be motivated by broader corporate considerations, shifting their objectives, and consequently, their strategic actions. Expecting subsidiary competitors to pursue business unit profitability can mislead managers toward pricing, product mix, or market entry errors. We present an important example from consumer finance, where independent auto lessors, such as Bank of America (BoA), compete with captive leasing subsidiaries like Ford Motor Credit (FMC). Since FMC is motivated to subsidize and support vehicle sales for its manufacturer parent, a cost advantage is not enough for BoA to dominate the market. Understanding broader corporate motivations of competitors helps managers anticipate competition levels in potential markets, thereby improving decision‐making and performance.

环境动态性视角下大数据能力对制造业绿色竞争力的影响机制研究——基于SBM-GML指数模型

随着数字经济兴起，大数据在降低环境成本、提高组织效益等方面显示出巨大潜力。选择包含非期望产出的SBM-GML模型，测算2014—2019年50家制造业上市企业绿色竞争力，并运用Stata16软件分析大数据能力对绿色竞争力的影响以及环境动态性在其中的调节作用。研究表明，大数据战略规划能力和大数据分析能力对绿色竞争力具有显著积极作用，非高新技术制造业当期与滞后一期的大数据管理能力能够提高绿色竞争力水平，高新技术制造业当期与滞后一期的大数据管理能力对绿色竞争力没有显著作用；环境动态性在大数据战略规划能力、大数据管理能力与绿色竞争力的关系中起正向调节作用，但是对大数据分析能力与绿色竞争力的调节效应不显著。     

团队跨边界行为与新产品开发绩效：设计创新能力的中介效应

设计驱动创新逐渐成为企业竞争中除市场创新和技术创新之外的第三种致胜方式，设计创新能力较强企业往往在市场上占据独特优势地位。基于团队学习理论，构建一个“行为-能力-绩效”双调节模型，探讨团队跨边界行为对于新产品开发绩效的作用机制和边界条件。结果表明：①团队跨边界行为对新产品开发绩效具有正向影响；②设计创新能力在跨边界行为对新产品开发绩效间起中介作用；③团队知识共享在跨边界行为和设计创新能力间起调节作用，团队知识共享越强，跨边界行为对创新设计能力的正向影响越大；④团队监督在设计创新能力与新产品开发绩效间起到调节作用，团队监督越强，设计创新能力对新产品开发绩效的正向影响越大。     

本地能力视角下战略性新兴产业政策扩散研究——以中国内地31省份新材料政策为例

识别产业政策扩散背后驱动因素能为政府科学制定政策和正确选择产业提供理论指导，本地能力对战略性新兴产业政策扩散具有重要影响。以2005-2018年新材料政策在我国内地31个省市区的扩散过程为例，分析省级战略性新兴产业政策扩散机制。研究发现：本地能力影响省级战略性新兴产业政策扩散，其中资源禀赋、产业实力和知识技能对政策扩散有正向影响，制度环境对政策扩散有负向影响；中央政府应避免强制推行产业政策导致的资源浪费，地方政府应因地制宜地发展战略性新兴产业并不断增强本地能力建设。     

Gender Roles and Labor Use Strategies: Women's Part-Time Work in the European Union

Progress towards equal opportunities is critically dependent upon the development of a more equal and more balanced allocation of time in both paid and unpaid work. Gender divisions relating to working time arise primarily from differences in gender divisions within the household but the extent and form that these gender divisions take in the labor market are moderated or mediated by national working-time regimes. These regimes are found to be extremely diverse across Europe with very different implications for gender equality. Current interests in greater flexibility in working time are leading to pressures to changes in working-time regimes and to an increase in the extent of unsocial hours working. The strategies adopted to meet these pressures may vary by country and sector but the restructuring of working time is also likely to be influenced by gender factors and divisions. The result may be increasing differentiation by both gender and class. Progress towards equality requires a renewal of interest in reducing standard working hours and a questioning of the current assumption that increasing unsocial hours working is essential for competitiveness.
