To look tasty,let's show the ingredients! Effects of ingredient images on implicit tasty–healthy associations for packaged products

This study investigates the effect of ingredient images on implicit tasty–healthy associations for packaged products. An implicit association test (IAT) with 106 respondents reveals the impact of repeating ingredient images on the implicit healthy = tasty intuition; fewer ingredient images are linked to a stronger intuition. This study also considers explicit product packaging preferences and the number of ingredient images depicted. The implicit intuitions affect explicit preferences, such that packages depicting few ingredient images are preferred over those depicting many ingredient images for healthy products, but no significant effects emerge for unhealthy products.     

基于跨国并购的创新网络嵌入、网络异质性与创新质量研究

区别于现有研究通常将跨国并购视为一个“事件”研究其对并购企业技术创新的影响，基于创新网络视角，文章采用中国上市公司数据，通过关系嵌入和结构嵌入两个维度探讨基于跨国并购的国外创新网络对创新质量的影响机制。研究发现，通过跨国并购嵌入创新网络的直接联系促进了创新质量提升，间接联系和结构洞对创新质量产生了显著的抑制效应。网络异质性对基于跨国并购的创新网络嵌入与创新质量具有倒U型调节作用，在网络异质适度阶段，网络异质性正向调节基于跨国并购的创新网络嵌入的创新质量效应，在网络异质过度阶段，网络异质性具有负向调节效应。研究发现为新兴经济体企业实施跨国并购，有效嵌入国外创新网络，配置创新资源，提升创新质量，提供了有价值的参考。     

The impact on stock prices of deferral and elimination of internal control audit requirement for small firms

This paper examines the cumulative market reaction to the events related to deferral of internal control audit requirement under the Sarbanes-Oxley Act of 2002 and its elimination under the Dodd-Frank Act of 2010 for nonaccelerated filers (small firms). We document that small firms experienced negative cumulative abnormal returns around these events; and the differences between the cumulative abnormal returns for small firms and the two control groups (accelerated and large accelerated filers) were negative and significant at the 1% level. These results support the notion that market participants value the reliability of financial information irrespective of the firm size. Within the small firms, we find no firm characteristic significantly explains the market reaction to the events considered. That is, all small firms lost market value in reaction to the events that delayed and eliminated their internal control audit requirement.     

科技企业孵化器何以激活区域创新——风险投资与孵化基金的中介作用

完善创新生态系统、提升区域创新能力是我国科技企业孵化器建设的重要目标。基于2013-2018年中国（内地）30个省份面板数据，采用面板数据模型实证检验科技企业孵化器是否促进了区域创新能力提升，并基于中介效应模型探讨风险投资和孵化基金在其中的间接作用。结果发现：①科技企业孵化器建设显著提升了区域创新水平，但主要增加的是实用新型和外观设计专利申请授权数总量，对发明专利申请授权数并没有显著促进作用。上述结果在剔除直辖市样本、采用随机效应模型及空间计量模型的稳健性检验后依然成立；②通过中介效应模型检验发现，区域风险投资和孵化基金集聚效应是科技企业孵化器影响区域创新水平的主要机制；③科技企业孵化器对区域创新的影响在不同区域间差异较大，在东部地区的创新激励效应更加显著，而且政策工具强度对科技企业孵化器与区域创新水平的关系具有正向调节作用。     

Alternative balanced scorecards built from paradigm models in strategic HRM and employment/industrial relations and used to measure the state of employment relations and HR system performance across U.S. workplaces

This paper constructs alternative balanced scorecards based on high‐performance work system (HPWS) and employment relations system (ERS) models. The models are depicted and compared in diagrams and used as framework skeletons for building separate HPWS and ERS scorecards, intended to provide a detailed data picture of the operational health and performance of an organization's employment/HR system and its operations, processes, and inputs/outputs. The scorecards are filled in with nationally representative data from 2,000+ U.S. workplaces using more than 50 employment/HR indicators, as reported by separate panels of managers and employees. The indicators for each workplace are aggregated into an overall HR/employment system score, ranked from low‐to‐high, and graphed as frequency distributions. These distributions provide a unique snapshot picture of the mean and dispersion of the state of employment relations and HR system performance for companies across the United State. They also reveal that “models matter” since the HPWS and ERS scorecards provide distinctly different evaluation assessments.

An integrated approach to the purchase decision making process of food-delivery apps: Focusing on the TAM and AIDA models

The study employed two theories, the technology acceptance model (TAM) and the Attention-Interest-Desire-Action (AIDA) model, to provide an understanding of the process of consumers accepting an on-demand food-delivery app, and to establish the effect of marketing communication on outcomes related to consumer behavior. A conceptual model and hypotheses were developed by combining the key constructs of the two models to predict behavioral intentions. Findings revealed the attention and interest in the AIDA model related strongly to the salient behavioral beliefs of TAM, perceived usefulness and perceived ease of use. Thus, it can be concluded that marketing communication acts as an external element in the process of accepting new innovations. Besides, it was confirmed that attitude towards the adoption of new technology acts as a mediator that promotes desire for the app. From the disciplines of information system and marketing communication, the study suggests an innovative approach to incorporating models.     

毛竹水溶性多糖提取工艺的优化及结构表征

产业融合对中国装备制造业创新效率的影响:结构嵌入的调节作用

从理论和实证两个方面探讨了产业融合对中国装备制造业创新效率的影响，以及网络中心性和网络异质性对二者关系的调节作用。基于2006—2015年省际装备制造7个子行业面板数据，采用ISCNFI指数测度模型和基于产出距离函数的超越对数前沿分析方法，分别测度装备制造业产业融合程度及创新效率变化情况，进而利用面板回归模型对理论假设进行实证检验。结果显示：产业融合程度与中国装备制造业创新效率存在倒“U”型曲线关系，即随着产业融合程度提升，中国装备制造业创新效率呈现出先上升后下降的变化趋势；网络中心性强化了产业融合对装备制造业创新效率的提升作用，而网络异质性削弱了产业融合对装备制造业创新效率的提升作用。     

Residential segregation and educational attainment of children from regional migrant families in China

This paper studies the residential segregation effects on educational attainment of children from regional migrant families in China. We find that if migrant families live in segregated communities with fewer local residents, the school dropout rate of the children living with their parents in the host cities is higher and their high school enrollment rate is lower. We employ a unique set of nationwide survey data of regional migrants in China in 2012 and 2013 that comprises more than 150,000 individuals in each year. We first use the ratio of migrants over the total population residing in a community to measure segregation. When the ratio increases by 10%, the school dropout rate of migrant children increases by 4.7% from the mean value. Secondly, we identify segregation from the housing type of the migrant family. When they reside in the dorms provided by their employers or in the workplace, they will also be surrounded by many migrant colleagues. We find that living in such places increases the “not‐going‐to‐high‐school rate” of migrant children by 35% from the mean value. Our subsample analysis indicates that the segregation effects only exist in the samples of male migrant children and rural hukou families.
