Manufacturer rebate and channel coordination in O2O retailing

Many manufacturers are opening their own online channels due to the growth of e-commerce leading to intensive channel competition with their offline retailer partners. This research proposes an innovative coordination mechanism to lessen channel competition and help enhance the profits of all parties. First, two strategic mechanisms (i.e. a manufacturer rebate to offline consumers and the quantity discount) are proposed and studied. Our results show that although a manufacturer rebate offered to offline consumers helps mitigate the online-to-offline (hereafter O2O) competition conditionally, a quantity discount, unexpectedly, cannot be used to mitigate channel competition effectively. A new mechanism - the combination of the manufacturer rebate to offline consumers combined with a quantity discount to retailers – is developed to lessen channel competition. We find that compared to the first two mechanisms, the combination mechanism, surprisingly, provides a significant advantage in creating greater profits for the entire supply chain. Furthermore, compared to the benchmark O2O model, the combination mechanism also helps create a Pareto situation and thus is an optimal mechanism to be used to mitigate channel competition effectively.     

Life satisfaction and support for tourism development

The purpose of this study is to better understand local residents’ support for tourism development by exploring residents’ perceived value of tourism development, life domain satisfaction (material/non-material), and overall quality of life in their community. The study provides the theoretical and empirical evidence of the relationships among those constructs. Using a sample of residents from five different tourism destinations, the results of a structural equation modeling approach indicated that residents’ perceived value of tourism development positively affects non-material and material life domain satisfaction; thereby, it contributes to overall quality of life. Finally, overall quality of life is an effective predictor of support for further tourism development.     

Institutional monitoring,coordination and corporate acquisitions in China

Within the context of corporate acquisition decisions of China’s Publicly Listed Corporations (PLCs), this paper investigates the monitoring and coordination behaviour of institutional shareholders. Institutional shareholders are divided into four groups: large outsider, large insider, small outsider and small insider. The outsider and insider categorization, respectively, represents the absence of significant business links with relevant PLCs. In China, institutional shareholders tend to either monitor the acquisitions decisions of PLCs or coordinate their response with the controlling shareholders (coordination in the present context amounts to cooperation). Using micro data from China’s stock market over the 2003–2008 period, we find that (through ex-ante coordination with the controlling shareholders) the insider institutional investment tends to increase the likelihood of PLC acquisitions. However, through ex-ante monitoring of the PLC acquisition offers, the outsider institutional investment tends to decrease the acquisition likelihood. We find that, through ex-post monitoring of PLC acquisitions, institutional investors with large shareholdings can help improve the post-acquisition performance of Chinese PLCs. On the other hand, institutional investors with small shareholdings tend to coordinate their actions with the controlling shareholders. Accordingly, small institutional shareholders cannot affect the post-acquisition performance of China’s PLCs. Finally, we find that the so-called ‘cherry-picking effect’ exists only in the case of large outsider institutional investors.     

粤港澳大湾区创新系统耦合协调空间结构与联系研究

深刻把握区域创新系统内部耦合特征与协调机制，是科技强国战略下激发粤港澳大湾区城市群创新活力，进而提升核心竞争力的首要问题。基于复杂网络理论与地学空间方法，利用熵权TOPSIS模型、耦合协调模型、莫兰指数、引力模型、社会网络分析法，探索粤港澳大湾区创新质量与创新氛围耦合协调的空间结构。研究发现：①区域创新系统的综合得分呈现“中轴高—四围偏低”的空间结构，广州和深圳的创新氛围与创新质量的耦合协调度均较高，说明两系统间呈现出有序的螺旋优化状态，而澳门的创新发展存在双重错位现象；②耦合协调度具有显著正向空间相关性，局部空间关联模式分异明显，粤港澳大湾区已形成联系紧密的环形创新网络结构，网络空间交易成本和同配性现象显著，深港创新集群的耦合协调联系最为紧密。     

区域一体化提升企业绩效的政策效应研究——以“长三角城市经济协调会”为准自然实验的经验分析

区域一体化通过资源共享、市场共建、产业共兴、政策共商等路径改善企业的内部生产条件和外部营商环境,降低企业生产成本和交易成本,进而促进企业绩效的提升。以“中国工业企业数据库”中1996—2013年沪苏浙皖的制造业企业为样本,将企业所在城市是否加入“长三角城市经济协调会”作为准自然实验,采用PSM-DID方法分析区域一体化影响企业绩效的政策效应,结果表明：总体上,区域一体化对企业绩效具有显著稳健趋于强化的促进作用,且后期加入企业具有较强的预期效应;区域一体化对多数行业的企业绩效具有提升作用,但对少数行业的企业绩效有不利影响;区域一体化前期对规模较大企业的绩效提升更显著,而后期对规模较小企业的绩效提升更显著;入会城市距离核心城市上海越远,区域一体化提升企业绩效的政策效应越弱。在发挥区域一体化提升企业绩效的积极作用时,应注意政策效应的多样化和多变化,尽量平衡各地区和各类经济主体之间的政策效应差异;同时,应实施多层次区域一体化战略,弱化城市距离对区域一体化政策效应的消减作用。     

基于DEA-C^2R模型的区域交通运输协调效率分析

交通运输是社会经济发展的基础。通过提高不同交通运输方式之间的协调效率可以实现同等交通规模下交通综合运输能力的提高。选取不同交通方式的合理指标和数据,采用数据包络分析的方法对不同交通运输方式之间的运行效率进行分析,通过效率变化情况说明区域交通运输主要构成方式之间的协调配合水平。实证研究结果表明,通过不同交通方式之间的协调效率提高,可以减少交通对土地、能源和环境影响,实现区域交通运输能力的提高。     

黑龙江省发展森林碳汇贸易实证研究

森林生态系统在全球碳循环与平衡中具有极为重要和不可替代的作用。黑龙江省森林资源丰富,是我国最主要的林区,巨大的"碳汇"既具有重要的生态功能,也蓄藏着潜在的巨大经济利益。本文运用森林蓄积量扩展法,依据黑龙江省《关于加强林业强省建设的决定》中确立的目标,分别计算了黑龙江省2010年和2020年的森林生物量碳汇贸易潜力和森林全部碳汇贸易潜力。计算结果表明黑龙江省森林碳汇贸易潜力巨大。与此同时,本文在实证研究的基础上,为了使黑龙江省的森林碳汇贸易潜力得以更好地发挥,也提出了一些可行性建议,这些建议能否收到实效,还有待实践予以证明。
