For green or not for green? The effect of cooperation goals and type on environmental performance

Although many scholars have demonstrated that companies engaged in collaborations achieve better environmental performance than other companies, existing studies have not analyzed in depth whether this effect changes considering the characteristics of cooperation. Our paper aims to explore whether collaboration with other companies always has a positive effect on environmental performance or whether it depends on cooperation goals, collaboration type, or company size. Empirical analysis based on a sample of 773 European companies demonstrated that an external source of knowledge is an important way to foster firms' environmental proactivity, especially when environmental goals are shared at the basis of collaboration. Second, we verified that companies involved in JVs with environmental goals achieve greater environmental performance than companies that use M&As to acquire external knowledge. Finally, we demonstrated that it is more important for small companies to be involved in environmental collaboration than larger ones.     

渠道合作情境下合同双元功能对主动和被动投机行为的影响差异研究

基于交易成本理论，在渠道合作情境下，以制造商的合同监督和企业间联合行动为工具测量合同治理的保障功能和协作功能，探讨二者对经销商主动投机行为和被动投机行为的影响差异。通过对512份问卷数据的统计分析，得到以下结论：第一，合同监督有助于抑制经销商的主动投机行为，但对其被动投机行为的影响不显著；第二，企业间联合行动有助于抑制经销商的被动投机行为，但对其主动投机行为的影响不显著；第三，经销商的主动投机行为和被动投机行为均会负向影响合作绩效；第四，经销商的主动投机行为中介合同监督对合作绩效的正向影响，被动投机行为中介企业间联合行动对合作绩效的正向影响。     

Resolving post-formation challenges in shared IJVs: The impact of shared IJV structure on inter-partner relationships

The “50/50”, or the shared management international joint venture (shared IJV) remains a popular and yet challenging control structure to govern IJVs. The purpose of this study is to understand the post-formation management of shared IJVs, specifically the relationship between shared structure, relational conditions and management of post-formation challenges. Our evidence is based on 26 in-depth interviews across four cases of shared IJVs between British multinationals and Asian companies. Our findings indicate that the highly integrative nature of shared IJVs, including high operational interdependence and shared decision-making, encourages partners to work closely together, communicate frequently and intensely and exchange personnel. Although share management can lead to inter-partner conflicts, the equal investment and mutual responsibility partly provides partners with motivation and opportunities to learn about each other, to better implement the control structure, to build trust, and to commit to the venture and partner. These relational conditions facilitated the successful management of post-formation challenges such as diversity related conflicts and macro volatility.     

Inter‐firm R&D collaborations and green innovation value: The role of family firms' involvement and the moderating effects of proximity dimensions

The present paper investigates the relationship between the involvement of family firms in R&D collaborations aimed at developing green solutions and the value of resulting innovations. To dig into this relationship, the moderating effects of two proximity dimensions (i.e., geographical distance and technological relatedness) are also assessed. Analyses are based on a sample of 156 joint patents classified into the “Alternative energy production” field, as defined by the International Patent Classification Green Inventory and successfully filed at the United States Patent and Trademark Office in the period 1997–2010 by publicly listed companies. According to our conjectures, results reveal a positive relationship between the involvement of family firms and green innovation value. Moreover, our findings show that this relationship is hindered when partners are geographically distant or technologically proximate. Eventually, we contribute to the literature on green innovation by unveiling under which conditions inter‐firm R&D collaborations lead to more valuable innovations.     

中国零售业自营与联营问题的流通经济学分析

零售业自营与联营之争由来已久，在当前供给侧结构性改革、完善促进消费体制机制以及零售业寻求创新发展的背景下，有必要对这一问题展开进一步的理论探讨。文章结合马克思流通经济理论指出，自营和联营的本质区别在于是商业资本还是产业资本承担商品流通职能，自营和联营并不是非此即彼的互斥关系，但如果零售业完全倚重其中一种模式并在全社会推向极端，则需要反思商业资本和产业资本是否各得其所和高效分工。在中国流通体制变革中，虽然联营模式在特定历史时期帮助众多零售企业渡过生存危机并推进内资零售快速扩张，但发展至今，已呈现零售业普遍联营的情况，使零售业整体面临着制约创新发展的新问题。数字经济为零售业回归自营提供了有利契机，零售企业应充分利用新技术摆脱联营制的路径依赖，依托数字化开展深度自营并全面提升流通效率。     

空间目标的联合矩阵束极点估计

极点作为谐振区雷达目标的最主要电磁特性，具有很大的空间目标识别前景。但是在使用频域观测数据提取目标极点时，存在虚假极点和估计精度问题。针对上述问题，首先通过加窗和截断改进了后时响应信号的获取流程，抑制了虚假极点影响；然后采用最小描述长度法（MDL）估计极点个数，避免了定阶错误引起的虚假极点；最后采用联合矩阵束法估计极点，有效减少了单角度数据估计极点时存在的遗漏极点和虚假极点问题。FEKO软件验证表明，所提算法具有更高的精度和抗噪能力。     

International joint ventures research on Africa: A systematic literature review,propositions, and contextualization

This study reviewed the research on international joint ventures (IJVs) in Africa up to 2017. The authors performed a systematic search of peer‐reviewed good‐quality research using the 6W procedure and ensured the quality of the review by using the 5Cs quality criteria. The content analysis was focused on four research questions. A total of 22 relevant studies were found. Overall, only about one‐third of the lead authors were affiliated with African universities. A majority of the studies were quantitative, and 78% of the studies were done for three countries: Ghana, Morocco, and Nigeria. There was either just one or no study on trust and conflict, partner selection, and human resource management (HRM). At the contextual level, it seems the most important factor influencing IJV strategy and success is institutions. We therefore suggest a greater use of institutional theory. Finally, we present a summary of conceptual framework and four propositions to guide future research.

Modelling tourist flow association for tourism demand forecasting

The purpose of this study is to examine tourism demand for Singapore from 1995 to 2013 by six major origin countries which belong to three different regions. Unlike prior tourism research, we take into account the dependence relations among the different tourist flows via copula. Copula is a statistical model of dependence and measurement of association. Specifically, we investigate the association between two tourist flows in each region. Based on empirical copula estimation, the Frank function has been identified as the most appropriate to capture the pairwise dependence structures of tourist flows. The copula-based approach combined with econometric models is proposed for tourism demand analysis that can be used to predict tourist arrivals. We apply the copula-ARDL and copula-ECM frameworks to generate joint forecasts of tourist arrivals from three regions. The findings show that the forecast performance of the Frank copula-based model outperforms the benchmark model which corresponds to the independence structure (no association) of tourist flows.     

城镇化背景下治安治理社会化的探索与创新——以钱江世纪城派出所“物业联席会”创建为例

治安治理社会化的核心是社会力量的参与。从宋代的民治传统到建国以来的政策与实践探索,从警务社会化、治安管理社会化到治安社会化、社会治安社会化治理等概念的相继提出,构成了治安治理社会化的演进脉络。治安治理社会化的本质是治安秩序维护的多元化,强调多元化共治、过程性理念与互动性思维的有机统一。杭州市公安局萧山区分局以“物业联席会”机制创建为载体,整合社会资源,激发社会组织活力,为治安治理社会化提供了更多可能的路径。借鉴“物业联席会”的创建经验,城镇化背景下的治安治理社会化应坚持党委组织领导,协同推进组织载体创新、联动机制创新与智慧化手段运用相融合。
