Abstract
Purpose
As returns to scale (RTS) describes the long run connection of the changes of outputs relative to increases in the inputs, the purpose of this study is to answer the following questions: If the proportionate changes exist in the inputs, what is the rate of changes in outputs with respect to the inputs’ variations in the two-stage networks over the long term? How can the authors investigate quantitative RTS in the two-stage networks? In other words, the purpose of this research is to introduce a different approach to estimate the performance, RTS and scale economies (SE) in network structures.
Design/methodology/approach
This paper proposes a novel non-radial approach based on data envelopment analysis to analyze the performance and to investigate RTS and SE in two-stage processes.
Findings
The findings show that the range adjusted measure (RAM)/RTS approach can identify reference sets for overall systems and each stage. In addition, the models presented in this paper can classify decision-making units and determine the increasing/decreasing trends of RTS.
Originality/value
The majority of previous RTS studies have been examined in black-box structures and have been discussed in a radial framework. Therefore, in this study, RTS and SE in the two-stage networks are dealt with using an extended RAM approach. Actually, the efficiency and RTS for each stage and the overall model are calculated using the proposed technique.

Abstract
Past research on transformational leadership in organizations has neglected the organizational context in which such leadership is embedded, and the significance of the disposition of followers. The purpose of the present study was to enrich and refine transformational leadership theory by linking it to organizational context and the self-esteem of followers. It was expected that organizational characteristics and subordinatesʼ self-esteem could moderate the effects of transformational leadership behavior on job satisfaction, organizational commitment, and organizational citizenship behavior. Results revealed that only organizational-based self-esteem (OBSE) significantly moderated the impact of transformational leadership behavior on organizational citizenship behavior (OCB). Within-and-between-analysis procedures (WABA) were used to determine the appropriate level of data analysis. Research finding suggests that managers should provide individualized performance feedback for high OBSE subordinates and spend more time coaching those subordinates with low OBSE on a one-to-one basis.

Abstract
Pygmalion and charisma are mutually compatible leadership constructs that beg integration. They share some basic assumptions about human nature, about how leaders lead, and about how they could lead more effectively. Nevertheless, for the most part these constructs are discussed in disparate academic literatures. The present treatise integrates these somewhat divergent yet partially overlapping approaches to leadership and management. The differences between Pygmalion and charismatic leadership, and the commonalities that they share, are explicated. The aim is to understand better how leaders affect followers and how they can exert their influence with greater effectiveness. Some ideas for further research and for more effective management practice based on integration of Pygmalion and charisma constructs are presented. The result is a description of “charismatic Pygmalion,” an integrated management style that embodies both leadership constructs.

Abstract
Purpose
China's increasing income inequality might cause a series of problems, such as the slowdown of economic growth, social and economic tension, the decline of the ecological environment quality and the threat to citizens' health. Consequently, income inequality will inevitably affect the ecological well-being performance (EWP) level of China's provinces through the above aspects. Analyzing the impact of income inequality on EWP and its spatial spillover effects are conducive to improving the level of EWP in China. Therefore, the research purpose of this paper is to use China's provincial data from 2001 to 2017 to analyze the impact of income inequality on EWP and the spatial spillover effect based on the evaluation of the EWP value of each province.
Design/methodology/approach
At first, this study utilizes the super efficiency slacks-based measure model (Super-SBM model) to calculate the EWP values of 30 provinces in China, which can evaluate and rank the effective decision units in the SBM model and make up for the defect that the effective decision units cannot be distinguished. Then this study applies the spatial Durbin model and Tobit regression model (SDM-Tobit model) to explore the impact of income inequality and other influencing factors on EWP and the spatial spillover effects in adjacent areas.
Findings
Firstly, the average EWP in China fluctuated slightly and showed a downward trend from 2001 to 2017. In addition, the EWP values of the provinces in the western region are usually weaker than those in the eastern and central regions. Moreover, income inequality is negatively correlated with EWP, and the EWP has a spatial spillover effect, which means the EWP level in a region is affected by EWP values in the adjacent regions. Furthermore, the industrial structure and urbanization level are both negatively related to EWP, while technology level, investment openness, trade openness and education level are positively related to EWP.
Originality/value
Compared with the existing research, the possible contribution of this research is that it takes income inequality as one of the important influencing factors of EWP and adopts the SDM-Tobit model to analyze the impact mechanism of income inequality on EWP from the perspective of time and space, providing new ideas for improving the EWP of various provinces in China.

Abstract
Chapter Contribution
In this chapter, we will be exploring the role of leadership within small businesses. Leadership is an essential element in the management of any organisation and is even more crucial when it comes to small businesses. In particular, both the structure and the specific stage of development of small businesses determines the need for an evolving style of leadership. Unlike their counterparts at larger organisations, small business leaders usually have a higher level of hands-on involvement across multiple areas of responsibility, including strategic decision-making and financial management, as well as team leadership and motivation.
Some key leadership skills, such as having a clear vision, communicating successfully across all business levels, leading by example and keeping the team engaged, are shared by all enterprises, regardless of size and nature. It is critical for small business leaders to understand that each stage of an organisation’s lifecycle brings with it different opportunities and challenges that should be dealt with by adopting different leadership techniques. A ‘one-size-fits-all’ approach will not work, and could even become detrimental in the long term.
During an organisation’s early days, a leader’s main role is to inspire the individuals they work with by sharing their vision and purpose without the need for formal management processes. In this chapter, we will be exploring the above issues in relation to the role of leadership within small businesses in greater depth.

Abstract
Purpose
As the complexity and uncertainty of megaprojects make it difficult for traditional management models to address the difficulties, this paper aims to design a performance incentive contract through IT applications, thereby promoting the formation of an information-based governance mechanism for megaprojects and facilitating the transformation and upgrading of the construction management model of megaprojects to informatisation.
Design/methodology/approach
This paper introduced IT applications into the performance assessment and used the proportion of IT applications replacing traditional manual management as a variable. It analysed different replacement ratios to obtain the optimal solution for the change of contractors behaviours and promote the optimal performance incentive for the informatisation in megaprojects.
Findings
The results show that under the condition of the optimal replacement ratio, achieving the optimal state of a mutual win-win situation is possible for the benefit of both sides. The counter-intuitive finding is that the greater the replacement ratio is not, the better, but those other constraints are also taken into account.
Originality/value
This study enriched the research of the performance configuration incentive from a practical perspective. It extended the research framework of IT incentive mechanisms in the governance of megaprojects from a management theory perspective. It clarified the role of IT applications in incentive mechanisms and the design process of optimal incentive contracts under different performance incentive states. The incentives made the contractors work harder to meet the owner's requirements, and it could improve the efficiency of megaprojects, thus better achieving megaproject objectives.

Abstract
The current era is characterized by hyperturbulence, population growth, attention to food security, the need to identify sustainable strategies to reduce pollution and poverty, and the disparity between developed and undeveloped economies. These circumstances force a global paradigm shift based on sustainable practices and processes that put people and the environment at the core of each activity, contributing to sustainable, social, and economic development and promoting well-being in the community.
In this spirit, a strong impulse can derive from the practices of Green Technology, considered here as that set of processes aimed at eco-sustainability that acquire undisputed relevance, especially for emerging economies.
This chapter focuses on the role that Green technology practices exert in generating local well-being in the world's fifth-largest country: Brazil. Dynamic growth and effective social policies lifted millions of people out of poverty in the 2000s, even if socio-economic development varies widely across the country. Brazil is a leading global agricultural, minerals, and oil producer. The natural environment represents the primary source of Brazil's development that deserves to be protected and push firms and citizens to find new sustainable solutions based on green policies. Drawing inspiration from a Brazilian case study, this chapter proposes a set of building blocks that foster sustainable business practices in emerging countries.
The chapter is organized as follows: the first part introduces the concept of green technology practices; the second highlights the opportunities of green technologies; the third focuses on a single case study.

Abstract
Incentives are effective at enhancing productivity, but research also suggests that performance incentives can have “unintended negative consequences” including increases in hazard/injuries, increases in errors, and reduction in cooperation, prosocial behaviors, and creativity. Relatively overlooked is whether, when, and how incentives can be designed to prevent such negative consequences. The authors review literature in several disciplines (construction, healthcare delivery, economics, psychology, and [some] management) on this issue. This chapter, in toto, sheds a generally positive light and suggests that, beyond productivity, incentives can be used to improve other outcomes such as safety, quality, prosocial behaviors, and creativity, particularly when the incentives are thoughtfully designed. The review concludes with several potential fruitful areas for future research such as investigations of incentive-effect duration.

Abstract
Purpose
Promoting low-carbon in the construction industry is important for achieving the overall low-carbon goals. Public–private partnership is very popular in public infrastructure projects. However, different perceptions of low-carbon and behaviors of public and private sectors can hinder the realization of low-carbon in these projects. In order to analyze the willingness of each stakeholder to cooperate towards low-carbon goals, an evolutionary game model is constructed.
Design/methodology/approach
An evolutionary game model that considers the opportunistic behavior of the participants is developed. The evolutionary stable strategies (ESSs) under different scenarios are examined, and the factors that influence the willingness to cooperate between the government and private investors are investigated.
Findings
The results illustrate that a well-designed system of profit distribution and subsidies can enhance collaboration. Excessive subsidies have negative impact on cooperation between the two sides, because these two sides can weaken income distribution and lead to the free-riding behavior of the government. Under the situation of two ESSs, there is also an optimal revenue distribution coefficient that maximizes the probability of cooperation. With the introduction of supervision and punishment mechanism, the opportunistic behavior of private investors is effectively constrained.
Originality/value
An evolutionary game model is developed to explore the cooperation between the public sector and the private sector in the field of low-carbon construction. Based on the analysis of the model, this paper summarizes the conditions and strategies that can enable the two sectors to cooperate.
