Abstract

The widespread family businesses play an important role in the national economy of developed countries in Europe and North America, or of developing countries in East Asia. However, family business succession is a worldwide difficult problem. The innovative family business succession practices of Robert Bosch GmbH, the German family company which has a history of 130 years (1886-2016), basically follow the trend of evolving from family businesses to social enterprises after further socialization. However, it has its own innovation and uniqueness which is worthy of reference by Chinese family businesses.

Abstract

Purpose

The purpose of this paper is to empirically analyze the impacts of motivation for avoiding loss and actual abnormal audit fees on management behaviors of audit opinion shopping.

Design/methodology/approach

Using empirical research methods, this study employs regressive models and moderating effect models with data from Chinese listed companies from 2001 to 2008.

Findings

By analyzing the empirical data, it is found that strong motivation for avoiding loss has a certain moderating effect on the relationship between abnormal audit fees and audit opinion shopping; abnormal descent of audit fees significantly increases both the likelihood of receiving modified audit opinions of annual financial reports and that of the improvement of audit opinions; listed companies reporting consecutive losses in the last two years have a higher likelihood of an improvement in unfavorable audit opinions because of stronger motivation for avoiding loss and audit opinion shopping of management; and strong motivation for avoiding loss has a significant moderating effect on the relationship between abnormal increase of audit fees and audit opinion shopping.

Practical implications

This study has a significant practical implication for market supervisors, small and medium investors.

Originality/value

The paper classifies abnormal audit fees into abnormal increase and descent of audit fees, and audit opinions differences into the improvement and deterioration of audit opinions, and further empirically analyzes and verifies the moderating effect of motivation for avoiding loss on the relationship between abnormal audit fees and audit opinion shopping.

Abstract

Purpose

Overconfidence as an important psychological factor can also affect CEO’s cognitive preferences, while there are few studies about the impact of CEO’ overconfidence on the international expansion of companies. This paper aims to fill this gap and further discuss the moderating role of CEO’s overseas experience, CEO duality and ownership.

Design/methodology/approach

The authors focus on the Chinese context, collect 2008–2016 data from China's manufacturing industry as sample, use fixed effect model to analyse the effect of CEO overconfidence on international expansion strategy of Chinese firms.

Findings

The empirical results show that: CEO overconfidence positively promotes the degree of firm internationalization. CEO foreign experience positively affects the internationalization degree, but can restrain overconfidence thus negatively regulate this impact relationship. When duality is present, both CEO power and managerial discretion are pronounced and they exhibit a stronger effect. Firm’s equity nature will affect the relationship between CEOs' overconfidence and the degree of internationalization. Compared with private enterprises, CEOs in state-owned enterprises have limited power, therefore, this influence relationship is weaker.

Originality/value

This study has emphasized the importance of top executives' psychological characteristics on firm internationalization, which is key application and complement of upper echelons theory and fills the research gap in the literature. In this paper, the authors found the advantages of overconfidence for firms, which helps to understand the complex meaning of overconfidence. The results of moderating effect further explore the application of overconfidence in different context, which has some implications for management practice.

Abstract

Purpose

The purpose of this paper is to combine triboelectric nanogeneration technology with ball bearing structure to achieve energy collection and fault monitoring.

Design/methodology/approach

In this paper, according to the rotation mode of ball bearings, the freestanding mode of triboelectric nanogeneration is selected to design and manufacture a novel triboelectric nanogeneration device Rolling Ball Triboelectric Nanogenerator (RB-TENG) which combines rotary energy collection with ball bearing fault self-sensing.

Findings

The 10,000s continuous operation experiment of the RB-TENG is carried out to verify its robustness. The accurate feedback relationship between the RB-TENG and rotation velocity can be demonstrated by the fitting comparison between the theoretical and experimental electrical signal periods at a certain time. By comparing the output electrical signals of the normal RB-TENG and the rotor spalling RB-TENG and polytetrafluoroethylene (PTFE) balls with different degrees of wear at 500 r/min, it can be concluded that the RB-TENG has an ideal monitoring effect on the radial clearance distance of bearings. The spalling fault test of the RB-TENG stator inner ring and rotor outer ring is carried out.

Originality/value

Through coupling experiments of rotor spalling fault of the RB-TENG and PTFE balls fault with different degrees of wear, it can be seen that when rotor spalling fault occurs, balls wear has a greater impact on the normal operation of the RB-TENG, and it is easier to identify. The fault self-sensing ability of the RB-TENG can be obtained, which is expected to provide an effective scheme for monitoring the radial wear clearance distance of ball bearings.
