浅议企业研究开发费用的会计处理

企业研究开发费用的会计处理,主要是无形资产的会计处理问题。焦点是如何确认自创无形资产过程中发生的研究与开发支出。汇集资本化和费用化两派观点,对企业研究开发费进行对比分析,引入数理模型可确定各因素的权重,进行精确的比较权衡,有利于在会计处理上使企业研发费用部分资本化,有利于企业发展,是可行的选择。

Best friend or broken tool? Exploring the co-existence of humans and artificial intelligence in the workplace ecosystem

Artificial intelligence (AI) has become an important topic in business literature and strategy talk. Yet, much of this literature is normative and conceptual in nature. How organizational members perceive AI and the job role changes that come with it is, so far, largely unknown territory for both HR scholars and practitioners. We sought to investigate the relationship between humans and AI and conducted an in-depth exploratory study into the co-existence of humans and two early-stage AI-solutions, one for “low-status” automation and another for “high-status”; augmentation. We suggest that different organizational groups may engage in distinctly different sensemaking processes regarding AI, an important insight for successful HRM strategies when AI is being introduced into the workplace. Moreover, contrary to recent conceptual work, our findings indicate that AI-enabled automation and augmentation solutions may not be detached from nor exist in tension with each other. They are deeply embedded in organizational processes and workflows for which people who co-exist with the technologies must take ownership. Our findings, in part, go against discussions on AI “taking over” jobs or deskilling humans. We describe a more nuanced version of reality fluctuating around the various ways different organizational groups encounter different AI-solutions in their daily work. Finally, our study warns against unconditional technological enthusiasm, managerial ignorance of the nature of work that employees undertake in different organizational groups, and a neglect of the time and effort required to successfully implement AI-solutions that affect not only the home organization but also members of the broader ecosystem.     

Information assimilation and stock return synchronicity: Evidence from an investor relations management platform

In this paper, we employ a unique information assimilation measure for listed firms in China based on their communications with investors through an online platform designated by the China Securities Regulatory Commission (CSRC). We examine whether a firm's efforts in enhancing investors’ information assimilation, such as providing more quality clarifications and explanations, helps facilitate the incorporation of firm-specific information in stock prices and reduces stock return synchronicity. We find robust evidence that more quality-clarifying communications contribute to lower stock return synchronicity after controlling for other information sources, and the decrease in synchronicity is mostly due to increased firm-specific information rather than noise. The causal relationship is established using a stacking DID approach and a PSM method. In a further analysis, we find that more quality communications can strengthen investors’ reaction to good news and smooth their reaction to bad news. Our study provides direct evidence that enhanced information assimilation benefits firms by entrenching more firm-specific information into stock prices.     

京津冀科技园区科技创新与政府协同治理效应研究

推进科技园区协同创新成为京津冀三地政府实施协同治理的重要抓手和主要着力点。聚焦三地科技园区协同创新情况，运用复合系统协同度方法，对2014—2019年京津冀国家级科技园区创新协同度与有序度进行度量。研究结果显示，2014—2019年京津冀三地国家科技园区的创新协同度与有序度总体呈现上升趋势，但协同创新关系仍不稳定。因此，应破除行政壁垒，构建跨区域合作治理模式与利益共享机制，推动特色产业集群形成。
