The Effect of Leaders’ Tolerance on High Performers’ Turnover Intention: A Moderated Mediation Model 领导宽容对高绩效员工离职倾向的影响:一个有调节的中介模型
Biwei Zhang, Yiwen Chen, Shang Li
In order to explore the impact of leader's tolerance on employees’ turnover intention, and to study the mediator role of employees’ trust in leader as well as the role of employees’ task performance, a questionnaire survey was conducted on 584 ordinary professionals. The study results show that (1) there is a negative correlation between leader's tolerance and employees’ turnover intention; (2) trust in leader mediates the effect of leader's tolerance on employees’ turnover intention; (3) employees’ task performance moderates the effect of leader's tolerance on employees’ turnover intention. Negative relationship between leader's tolerance and employees’ turnover intention is strengthened when task performance is high rather than when it is low.
为了探讨领导者宽容度对员工离职意向的影响,研究员工对领导者信任的中介作用以及员工任务绩效的作用,对584名普通专业人员进行了问卷调查。研究结果表明:(1)领导者容忍度与员工离职意愿呈负相关;(2)领导者信任在领导者宽容对员工离职意向的中介作用;(3)员工的任务绩效调节了领导宽容对员工离职意向的影响。当任务绩效高时,领导容忍度与员工离职倾向之间的负向关系比任务绩效低时更强。

Adaptation Strategies to Increase Business Competitiveness in the Digital Era: an Empirical Study of Local Freight Firms in Thailand 数字时代提升企业竞争力的适应策略:泰国当地货运企业的实证研究
Teeraphorn Polhong, Suteera Chanthes, Nitiphong Songsrirote
Digitization plays a significant role in shaping modern business operations. The notion of digitalization is also included in Thailand’s recent national economic development policy, known as Thailand 4.0. Under the policy, rooted in the industry 4.0 concept, the country promotes economic growth with innovation and creativity and tries to move towards the digital economy. This paper presents an empirical study examining the business adaptation of local family firms facing opportunities and business challenges caused by the Thailand 4.0 policy and the digitalization motivation. It delivers empirical evidence on entrepreneurship development in local Thai cross-border freight family businesses trying to change to innovative firms. The researchers employed a qualitative research approach to investigate five purposively selected firms from Nakhon Phanom province of the North-East region of Thailand. The research data was collected using documentary analysis and semi-structured interviews with the owner-managers of the selected firms. Study results are delivered under two themes: developing innovative family entrepreneurship and digitalization in local cross-border freight firms. The results show that digitalization is adopted to improve three primary areas for strategic improvement in the transportation industry, including inventory, transport, and location strategies. Family power and control are founded to positively support the family business transformation towards industry 4.0 via business digitalization. Trained employees to gain sufficient knowledge related to digital transformation is also essential. The paper also identifies areas requiring further improvements, including systematic support from public authorities and reliable technology to help widen and sustain domestic and international business partnership networks.
数字化在塑造现代商业运作方面发挥着重要作用。数字化的概念也包含在泰国最近的国家经济发展政策中,被称为泰国4.0。根据该政策,植根于工业4.0概念,该国以创新和创造力促进经济增长,并试图向数字经济迈进。本文对泰国4.0政策和数字化动机所带来的机遇和挑战,对泰国本土家族企业的商业适应性进行了实证研究。它提供了泰国当地跨境货运家族企业创业发展的实证证据,这些企业试图转变为创新型企业。研究人员采用定性研究方法调查了泰国东北地区那空Phanom省有目的地选择的五家公司。研究数据是通过文献分析和与选定公司的所有者-经理的半结构化访谈收集的。研究结果分为两个主题:发展创新型家族创业和当地跨境货运公司的数字化。结果表明,数字化被用于改善运输行业战略改进的三个主要领域,包括库存、运输和位置策略。家族权力和控制的建立是为了积极支持家族企业通过业务数字化向工业4.0转型。经过培训的员工获得与数字化转型相关的足够知识也是必不可少的。该文件还指出了需要进一步改进的领域,包括公共当局的系统支持和可靠的技术,以帮助扩大和维持国内和国际商业伙伴关系网络。

Analysis of low-carbon strategies in supply chain with governmental intervention 政府干预下的供应链低碳战略分析
Feng Li, Yafei Zu
Recently, issues of carbon emissions are becoming more and more prominent, resulting in serious environmental problems. Many governments take actions to help enterprises to manufacture and sale products environmentally. This paper studies the impact of governmental intervention on the low-carbon strategies of the inter-organizations. Using the differential Stackelberg game model, a supply chain consisting of one manufacturer and one retailer is studied. Two situations including the market-base scenario and government-base scenario are considered. The optimal strategies of the effort on emission reduction and the retail price in these two situations are solved and compared. The results show that government's participation in regulation improves manufacturer's emission reduction effort and retailer's retail price. The numerical analysis further confirms the research results.

The Influence of Corporate Environmental Responsibility on Enterprise Value Under the Chinese Context: This paper expounds the influence of corporate environmental responsibility on enterprise value and the moderation effect of regional differences 中国背景下企业环境责任对企业价值的影响:本文阐述了企业环境责任对企业价值的影响以及区域差异的调节作用
Manna Liu, Lu Huang, Jiao Yi
With the deepening of the concept of sustainable development, building an ecological civilization and deepening environmental reforms have been elevated to an important level. Against this policy background, corporates are being asked to increasingly take on environmental responsibility, promoting low-carbon and sustainable development in cities. At the same time, in the long run, corporate responsibility for the environment also causes an increase in corporate value. Under the Chinese current development model, it is important for companies to achieve their own sustainable development while promoting the sustainable development of the cities in which they operate. We collected data from heavily polluting corporates from 2016 to 2018, and empirically examined the impact of corporate environmental responsibility on enterprise value under regional differences. It is concluded that Chinese enterprises' assumption of environmental responsibility is U-shaped correlated with corporate value, and regional differences moderate the correlation.
随着可持续发展理念的深入,生态文明建设和深化环境改革已上升到重要水平。在这种政策背景下,企业被要求越来越多地承担环境责任,促进城市的低碳和可持续发展。同时,从长远来看,企业对环境的责任也会导致企业价值的增加。在中国目前的发展模式下,企业在促进所在城市可持续发展的同时,实现自身的可持续发展是非常重要的。我们收集了2016 - 2018年重污染企业的数据,实证考察了区域差异下企业环境责任对企业价值的影响。研究发现,中国企业环境责任承担与企业价值呈u型相关关系,区域差异调节了这种关系。

Digitalization is becoming increasingly important for the success of companies. Therefore, it is important to understand which skills and characteristics digitally and at the same time financially successful companies have. For this purpose, many variables are analyzed using correlation analysis. The data for the analysis comes from the European Investment Bank Survey. This analysis shows that digitally and financially successful companies have strong planning and leadership capabilities. Digitization is lived as a success-critical activity. Companies that are very active in implementing digital products very often launch their own products and services around the world. Such companies invest in asset types such as land, other businesses, buildings and infrastructure and they have a high investment intensity (total investment/number of employees).

Gilma Toaza, Carlos Montenegro, Cristina Salazar
COBIT 2019 is in the early stages of professional and/or academic use; thus, the validation of its applicability is in development in various case studies reported in technical literature. The current research applies COBIT 2019 in the large I&T Department of a strategic military public organization of a developing country. The application uses the methodology recommended by the framework and complementary methods to design an IT governance system. Highlights of the results are the considerations about organization size, the characteristics of the public sector, and the influence of the context of a developing country. Furthermore, the report about the use of COBIT 2019 in this research contributes to expanding the knowledge about the IT governance systems design and exposes a helpful experience to the practitioners.
