Abstract

Purpose

Boundary layer ingestion (BLI) is one of the probable noteworthy features of distributed propulsion configuration (DPC). Because of BLI, strong coupling effects are generated between the aerodynamics and propulsion system of aircraft, leading to the specific lift and drag aerodynamic characteristics. This paper aims to propose a model-based comprehensive analysis method to investigate this unique aerodynamic.

Design/methodology/approach

To investigate this unique aerodynamics, a model-based comprehensive analysis method is proposed. This method uses a detailed mathematical model of the distributed propulsion system to provide the essential boundary conditions and guarantee the accuracy of calculation results. Then a synthetic three-dimensional computational model is developed to analyze the effects of BLI on the lift and drag aerodynamic characteristics.

Findings

Subsequently, detailed computational analyses are conducted at different flight states, and the regularities under various flight altitudes and velocities are revealed. Computational results demonstrate that BLI can improve the lift to drag ratio evidently and enable a great performance potentiality.

Practical implications

The general analysis method and useful regularities have reference value to DPC aircraft and other similar aircrafts.

Originality/value

This paper proposed a DPS model-based comprehensive analysis method of BLI benefit on aerodynamics for DPC aircraft, and the unique aerodynamics of this new configuration under various flight altitudes and velocities was revealed.

Abstract

Purpose

Innovative capabilities are essential for the survival and development of an organization. Previous studies have found a positive relationship between CEO transformational leadership (CEOTFL) and firm innovation. However, limited studies have endeavored to investigate the relationship between CEOTFL and firm innovation through the cognition and attitudes of the ordinary employees, despite their significant role in corporate innovation. Existing TFL literature has predominantly concentrated on “the close relationships” between leaders and their immediate subordinates, leaving the remote influence of CEOTFL on ordinary employees under-researched. Therefore, the current study aims to explain the relationship between CEOTFL and firm innovation from a micro-level perspective.

Design/methodology/approach

Multilevel and multi-sourced data from 1,627 employees across 145 firms was used to test the hypotheses in this study.

Findings

The results indicate that CEOTFL can enhance firm innovation by enhancing the collective task self-efficacy of regular employees. Moreover, this effect is not observed when employees are exposed to a low level of work–life balance practices.

Practical implications

The findings suggest that CEOs can perform increased TFL to promote firm innovation. It is recommended that CEOs demonstrate their TFL not only to their direct subordinates but also to regular employees using various methods, such as participating in corporate activities with employees, delivering public speeches and sending emails to employees. Meanwhile, the HRM system should consistently align with the CEO’s leadership approach within the organization.

Social implications

This study strengthens the importance of ordinary employees and their contribution to firm innovation.

Originality/value

The present study contributes to the literature on the micro-foundations of the relationship between CEOTFL and firm innovation by considering ordinary employee reactions as a mediator. Furthermore, this study enriches the CEOTFL literature by investigating the distant influence of CEOTFL on rank-and-file employees through the lens of social cognitive theory. Additionally, the authors expand cue consistency theory to the realms of CEO leadership and HRM literature by integrating CEOTFL and work–life balance practices into a unified model. The findings reveal the importance of coordination between CEO leadership and HRM systems within an organization. The inclusion of Chinese sample data in this study augments the cultural diversity of the sample within the CEOTFL literature.

Abstract

Purpose

Previous studies have produced inconsistent findings regarding the effects of resource constraints on corporate illegal behavior. This study aims to explore how entrepreneurial firms can overcome the difficulties generated by resource constraints.

Design/methodology/approach

Drawing on insights from general strain theory and focusing on listed entrepreneurial firms, this study proposes that failure to obtain enough resources through listing generates strain in the managers of listed entrepreneurial firms, driving them to resort to corporate financial fraud as a solution. Nevertheless, such relationships between resource constraints and the likelihood of corporate financial fraud can be weakened by innovation capability, because innovation capability can generate more confidence in their managers and relieve their strains, thereby dissuading them from engaging in corporate financial fraud.

Findings

According to our empirical results, both financial and human resource constraints are positively related to the likelihood of corporate financial fraud in listed entrepreneurial firms, but such effects can be mitigated by innovation capability.

Practical implications

This study provides practical implications for both regulators and managers by indicating that although entrepreneurial firms with resource constraints are more likely to commit financial fraud, innovation capability could be a strategic approach to enhance managers’ confidence and relieve the strain.

Originality/value

Our study contributes to the literature by enriching our understanding of the consequences of resource constraints in entrepreneurial firms and highlighting the strategic importance of innovation capability in mitigating such effects.

Abstract

Purpose

The purpose of this paper is to explore the relationships among demographic factors (gender, age, education, and income), consumer traits (technology anxiety, need for interaction, and technology innovativeness), and intention to use retail self‐checkouts.

Design/methodology/approach

A total of 285 usable responses are obtained through a web‐based survey after excluding non‐qualified respondents. Structural equation modeling is developed and tested.

Findings

The results of this paper demonstrate that demographic factors only indirectly influence intention to use retail self‐checkouts through consumer traits and thus the authors conclude that individual differences in the use of retail self‐checkouts can be attributed to consumer traits which are determined by some of the demographic factors.

Research limitations/implications

Demographic factors and consumer traits are only included as determinants of intention to use retail self‐checkouts. Therefore, future research could attempt to draw a comprehensive picture of retail self‐checkouts by incorporating other relevant factors.

Originality/value

By classifying individual difference traits into demographic factors and consumer traits, this paper provides more detailed explanations of the relationships among demographic factors, consumer traits, and intention to use retail self‐checkouts.

Abstract

Purpose

This study aims to examine whether a firm's demand for high-quality auditors is influenced by multiple large shareholders (MLS). As one type of ownership structure, MLS have gained popularity in China recently and have different types of large shareholders, including large institutional shareholder, large foreign shareholder and large state shareholder. The authors also examine whether different types of MLS have heterogeneous impacts on appointing high-quality auditors.

Design/methodology/approach

With a sample of 27,131 firm-year observations from Chinese public companies from 2003 to 2018, the authors use multivariate regressions to examine the effect of MLS on auditor choice. Heckman two-stage analysis, a firm fixed effects model, propensity score matching and difference-in-differences test are used as robustness checks.

Findings

This paper finds that the presence and power of MLS increase the likelihood of appointing high-quality auditors. With regard to the types of MLS, large institutional shareholders and foreign shareholders have significant positive effects on appointing high-quality auditors, while the presence of state-owned large shareholders has no effect on auditor choice. Further analyses reveal that the positive effect of MLS on high-quality auditor choice is more pronounced in firms with severe agency problems and information asymmetry. Taken together, these results suggest that MLS play a monitoring role by demanding high-quality auditors.

Originality/value

This paper contributes to the literature on the determinants of auditor choice. While prior studies primarily focus on the impact of concentrated ownership structure, corporate governance and the pressure from stakeholders on auditor choice, this paper complements the literature by providing evidence from the heterogeneous effects of different types MLS. This paper also extends the literature on the consequences of MLS from the perspective of auditor choice.

Abstract

Purpose

This study aims to determine the key indicators affecting the resilience of the construction supply chain to flooding and calculate the resilience of the urban construction supply chain in three cases city.

Design/methodology/approach

This study combines expert opinions and literature review to determine key indicators and establish a fuzzy EWM-GRA-TOPSIS evaluation model. The index weight was calculated using the entropy weight method, and GRA-TOPSIS was used for comprehensive evaluation.

Findings

The results of the study show that the three cities are ranked from the high to low in order of Hangzhou, Hefei and Zhengzhou.

Originality/value

The innovative method adopted in this study comprising EWM-GRA-TOPSIS reduced the influence of subjectivity, fully extracted and utilized data, in a way that respects objective reality. Further, this approach enabled the absolute and relative level of urban construction supply chain resilience to be identified, allowing improvements in the comprehensiveness of decision-making. The method is relatively simple, reasonable, understandable, and computationally efficient. Within the approach, the entropy weight method was used to assign different index weights, and the GRA-TOPSIS was used to rank the resilience of the construction supply chain in three urban cities. The development of resilience provides a robust decision-making basis and theoretical reference, further enriching research methods, and having strong practical value. The study serves to improve risk awareness and resilience, which in turn helps to reduce losses. It also provides enhanced awareness regarding the future enhancement of supply chain resilience for urban construction.

Abstract

The authors show that there is a negative relationship between economic policy uncertainty (EPU) and firm overinvestment using Korean data from 2007 to 2016. Since Jensen (1986) shows that a firm's free cash flow is an important factor of overinvestment, the authors examine how free cash flow influences the sensitivity of overinvestment to EPU. The authors find that a high level of free cash flow attenuates the negative effect of EPU on overinvestment. The authors find that there is no significant difference in the effect of EPU on overinvestment between Chaebol (Korean family-run conglomerates) and non-Chaebol firms, which is consistent with the literature that the features of Chaebol are weakening.

Abstract

Purpose

The purpose of this paper is to investigate linkages among competitive strategy, strategic capabilities, environmental uncertainty, and organizational performance in small and medium sized enterprises (SMEs) in China and the USA.

Design/methodology/approach

In China, a survey was administered to managers of SMEs in Shanghai and Guangzhou. In the USA, a survey was administered to managers of SMEs in three major cities. Competitive strategy, capabilities, uncertainty, and performance were measured by previously validated scales.

Findings

Findings support the integrity Miles and Snow generic strategic typology. Performance satisfaction was significantly lower in firms employing a reactor strategy as opposed to those employing prospector, defender, or analyzer strategies. Additional support was found for the concept of strategic clarity, as businesses reporting moderate strategic clarity had lower levels of satisfaction with performance than those reporting either a single strategy or a combination emphasis on three equal strategies.

Practical implications

Chinese SMEs tend to prefer cost-based approaches to their local markets. A differentiation market approach is challenging in most local Chinese economies due to the low wages of most jobs in an economy that is still largely centrally planned. In the USA, more disposable income leads to more market opportunities. While this situation is gradually changing in China, it is not at a point where SMEs feel comfortable pursuing totally differentiated strategies.

Originality/value

Several distinctions in competitive strategy, capabilities, and environmental uncertainty between China and the USA are recognized by analysis. Analyzers and defenders in Chinese SMEs tend to follow industry prospectors with lower prices and/or superior service. They might change strategies after gaining a foothold in the market. Performance for SMEs with low strategic clarity often depends on established guanxi with governmental agencies or stated-owned enterprises, a situation very different from that in the USA.
