When less is more? The contingent effect of product supply limitation in the release of new electronic products

In the market of consumer electronics, firms often limit their product supply to create a scarcity effect to entice consumers to buy their product. However, the outcome of such a strategy is not always desirable. In this study, we propose the product configuration level as a contingent variable that works with the supply level to affect the outcome of a supply limitation strategy. With a vignette-based experiment, we find that for a product with a superior configuration, consumers' purchase intention is boosted only if the supply is very limited. For a product with an inferior configuration, however, the supply limitation strategy does not work at any supply level. Therefore, the supply limitation strategy works only for a superior product configuration and at a fine-tuned supply level.     

Exploring the effect of buyer engagement on green product innovation: Empirical evidence from manufacturers

In this study, we are interested in how export firms organize knowledge management and increase product innovation performance. Prior studies have concluded that knowledge transfer from external actors leads to operational performance outcomes; others have questioned the positive influence of buyer-driven knowledge transfer activities on innovation performance. Drawing on absorptive capacity, we aim to offer a better understanding, how export firms as recipients of knowledge resources, organize their internal capabilities in order to realize firm-level product innovation. This empirical study examines the interplay of buyer-driven knowledge activities, resource acquisition and combining, and product innovation outcomes in the context of Pakistani export firms. Drawing on survey data from 239 export-manufacturing firms, we test hypotheses using structural equation modeling. Our findings show that buyer-driven knowledge transfer activities play a crucial role in enhancing export firms in absorbing and combining resources that lead to product innovation. The pragmatic suggestion of the research suggests that managers look closely at developing a culture of involvement with their buyers that promotes the development of knowledge resources. The results of this study have research, policy, and managerial implications.     

发展竞争、土地供应策略互动与城市用地增长——基于252个城市数据的空间面板模型实证检验

研究目的：针对发展竞争驱动下产生的地方政府土地供应策略，从空间维度上展开进一步分析，解析城市土地供应行为中存在着怎样的空间互动关系。研究方法：运用2007—2017年的城市层面面板数据和空间计量模型进行了实证检验。研究结果：（1）服务于发展竞争的土地供应策略，对本城市和周边城市的用地增长都会产生影响；（2）工业用地价格波动与商住用地价格波动都会产生空间溢出效应，且前者产生的空间溢出效应更强；（3）工业用地价格存在“竞次式”的城市间互动，其价格增长会显著抑制本城市的用地扩张，但会促进周边城市的用地增长；（4）商住用地价格提升会促进本城市用地扩张，并抑制周边城市用地扩张；（5）作为因变量的城市用地规模，在同省/异省的城市间分别存在着“彼此促进”和“此消彼长”两种互动关系。研究结论：区域协调、用地增长两个方面要紧密结合，针对工业用地价格“竞次式”竞争和商住用地价格高价出让，从城市间关系协调入手进行调控政策的设计与创新。     

基于预约策略的医院CT设备使用优化研究

预约检查是对有限的医疗检查资源的一种调度优化。以攀枝花市A医院CT检查为例,通过实地调研,统计CT设备的服务能力,门诊患者,住院患者和急诊患者的平均到达率,接受患者的单位检查收益和拒绝患者的单位检查损失。通过调整预约策略使有限的资源设备产生更多的收益,并运用仿真模拟不同预约策略下的收益效果。研究结果对医院重要设备的预约使用提供了一定参考价值。     

跨境电商英语沟通中的语用移情策略研究

跨境电商的飞速发展离不开跨境电商英语沟通质量的提升,跨境电商英语沟通是在交流过程中,买卖双方传递、共享信息和感情的过程。运用语用学的移情理论,结合跨境电商英语沟通特点,从礼貌语、委婉语、模糊语和幽默语等方面,建构语用移情策略,有助于缩短买卖双方的心理距离,达到预期的语用效果,推动畅通有效地跨境电商沟通。     

考虑零售商销售努力的双渠道供应链定价策略研究

随着电子商务市场的日益成熟,制造商建设线上直销渠道来适应新的商品销售环境成为趋势。制造商线上直销渠道的建立占领了部分原本属于线下零售渠道的市场份额,对线下零售渠道造成冲击。针对双渠道供应链中的竞争,将零售商销售努力行为考虑在内,通过构建博弈模型分别研究了在集中决策模式和分散决策模式下,制造商与零售商的定价策略。研究发现,在集中决策模式下,线下零售渠道与线上直销渠道之间的价格差异随着两个渠道潜在需求量之间差异的增大而增大,并且两个渠道的最优价格分别与其市场潜在需求成正比。在分散决策模式下,两个渠道的最优价格亦与潜在需求成正比,并且线下零售渠道的最优价格随零售商销售努力程度的增加而增加,线上直销渠道的最优价格随着零售商销售努力程度的增加而减少。     

中国自贸区战略实施的现状、效果、趋势及未来策略

随着全球经贸规则的加速重构,我国自贸协定的谈判和签署步伐明显加快,且签署协定的开放水平不断提升,协定实施对双边贸易也产生了显著的促进效果。未来,中国的自贸协定谈判将呈现出覆盖范围更广、开放层次更高、协定对象向重点国家和地区突破的态势。为了实现"形成覆盖全球的高标准自贸区网络"的目标,我国应通过积极参与构建超大型自贸区、将自贸区网络建设与"一带一路"倡议相结合、深化自身改革提供制度支撑、综合考量宏观收益开展自贸谈判、设计兼具稳定性和灵活性的自贸协定"范式"等策略来推进自贸区建设。

Does air pollution change a firm's business strategy for employing capital and labor?

We examine the impact of air pollution on a firm's capital-labor ratio. We propose the hypothesis that, in dealing with air pollution, a firm responds strategically by using relatively more capital and less labor to contain labor costs and remain competitive in the market. Using a sample of Chinese firms and a satellite-based air pollution metric, we test this hypothesis, and our results confirm it. In addition, we document that the impact of air pollution on the capital-labor ratio is more salient for firms with high economic incentives and close monitoring. Further, we report that to respond to worsening air pollution, a firm uses more capital and substitutes lower-quality labor with more high-quality labor. Finally, after increasing the capital-labor ratio, a firm's value increases, in terms of Tobin's Q, suggesting that the adoption of a higher capital-labor ratio, due to air pollution, is a sound business strategy.     

Going green,going clean: Lean‐green sustainability strategy and firm growth

Despite the widespread recognition of the paybacks of “going green” and “going clean,” limited research has focused on the impact of lean‐green strategy on firm growth. In this study, we contribute to strategy and environmental sustainability literatures by investigating the possibility that the influence on lean‐green strategy and firm growth is driven by different levels of industry competition, managerial power, and family ties. Using panel data from 732 firms in four major industrialized economies (the United States, Germany, France, and the United Kingdom), we found that lean‐green strategy positively relates to firm growth and this relationship is amplified at higher levels of competition, managerial power, and family ties. Theoretical and practical implications of the study are also discussed.
