Abstract

Purpose

The purpose of this paper is to study the aerodynamic characteristics and uplift force tendencies of pantographs within the operational height span of 1,600–2,980 mm, aiming to offer valuable insights for research concerning the adaptability of pantograph-catenary systems on double-stack high container transportation lines.

Design/methodology/approach

Eight pantograph models were formulated based on lines with the contact wire of 6,680 mm in height. The aerodynamic calculations were carried out using the SST k-ω separated vortex model. A more improved aerodynamic uplift force method was also presented. The change rule of the aerodynamic uplift force under different working heights of the pantograph was analyzed according to the transfer coefficients of the aerodynamic forces and moments.

Findings

The results show that the absolute values of the aerodynamic forces and moments of the upper and lower frame increase with the working height, whereas those of the collector head do not change. The absolute values of the transfer coefficients of the lower frame and link arm were significantly larger than those of the upper frame. Therefore, the absolute value of the aerodynamic uplift force increased and then decreased with the working height. The maximum value occurred at a working height of 2,400 mm.

Originality/value

A new method for calculating the aerodynamic uplift force of pantographs is proposed. The specifical change rule of the aerodynamic uplift force of the pantograph on double-stack high container transportation lines was determined from the perspective of the transfer coefficients of the aerodynamic forces and moments.

Abstract

Purpose

To help firms with their international operations, governments often create policies and support mechanisms, but its influence on the firm's exit decision has so far been ignored. Hence, the purpose of this study is to examine the impact of home-country governmental support on the firm's exit decision.

Design/methodology/approach

The authors test their conceptual model using multiple informants as well as secondary data from China. The sample consists of 360 valid questionnaires from 180 firms. Binary logistics regression is used to test the conceptual framework.

Findings

By demonstrating that resource-based and institutional constructs are highly dependent, the authors show how home-country governmental support interacts with the foreign affiliate's past performance to explain the decision to remain or exit a foreign market. The results indicate that while governmental financial support reduces the likelihood of exiting a poorly performing business in the foreign market, governmental non-financial support surprisingly has an opposite effect.

Originality/value

While there has been an increasing number of firms exiting foreign markets, this area of research is still limited. The study also contributes to the literature by focusing on home-country governmental financial and non-financial support to explain the firm's exit decision – an issue that has been ignored and is expected to be particularly relevant for firms from emerging economies.

Abstract

Purpose

The purpose of this paper is to analyze the relationships among organizational justice, innovative organization culture, perceived organizational support (POS), affective commitment and innovative behavior (IB). The mediating role of POS is tested within the relationship of justice dimensions, affective commitment and IB.

Design/methodology/approach

Data for this research were collected from 367 managerial and executive employees working in manufacturing and IT sector firms in Pakistan. Structural equation modeling was utilized to test hypothesized relationships.

Findings

Results indicate that organizational justice (distributive, procedural and interactional justice), innovative organization culture and POS are significantly related to affective commitment and employees’ IB. The findings also showed that organizational justice stimulates employees’ affective commitment and IB through mediating POS as well as directly.

Research limitations/implications

The main limitation of this study is its cross-sectional design and self-reported questionnaire data. This study is also limited to manufacturing and IT sector in Pakistan. Therefore, other sectors and geographical locations could be chosen for future research using a bigger sample size.

Originality/value

This study makes important theoretical contributions using social exchange theory. It also expands the research in the area of organizational justice dimensions, organizational culture and POS as antecedents of affective commitment and IB. This study is an exceptional investigation of justice, organization culture, POS, commitment and IB in the Pakistan cultural context.

Abstract

Purpose

This study aims to deem the new policy – talk for environmental protection – promoted in the second half of 2014 to be the exogenous event and adopts PSM and DID to verify whether and how the central government’s mechanism of supervision of environmental enforcement improves firm environmental performance and reveals the micro effect and working mechanism of the supervision of environmental enforcement.

Design/methodology/approach

The researchers first select reasonable control groups for target districts by means of PSM, then apply DID to compare corporations in the treatment group with those in the control group for the change of environmental performance before and after the talk for environmental protection, so as to evaluate the micro-level effect of such talks on corporate environmental performance; after that, the research examines the working mechanism of such talks on corporate environmental performance; then, it goes a step further to find out the environmental impact of such talks on corporations of different natures of property right.

Findings

It is found from the research that the talk for environmental protection will effectively improve the environmental performance of corporations in the target districts, and the improvement of environmental performance in state-owned corporations in the target districts will be more evident. However, such improvements, to a certain extent, are achieved by reducing the output value, and corporations do not increase environmental investments from a long-term perspective.

Research limitations/implications

First, the targets of the talk for environmental protection are mainly principals of municipal governments, but the research expands the scope to the whole province due to the small sample at the municipal level. Despite evidences showing that such a pressure of supervision impacts the whole province, the results obtained based on the data at the municipal level will be accurate. Second, the research selects a relatively short research period. Third, due to the limited data on corporate environmental performance in China, the research selects only listed companies from key monitored and controlled firms by state.

Practical implications

First, for the central government, environmental policy making is not the end of its job; it shall also supervise local governments’ work at environmental governance and properly handle its relationship with local governments. Second, for the local governments, in the course of implementing environmental policies, they should not only strengthen law enforcement but keep the continuity of law enforcement to avoid moving law enforcement. Third, in the long run, corporations must start from the source of production to enhance environmental governance and make cleaner production, so as to keep boosting corporate competitiveness and their ability of fighting risks.

Originality/value

First, the research innovatively provides empirical evidence about the effect of China’s supervision of environmental enforcement. Previous studies on this topic are mostly theoretical discussions only, while this research makes the talk for environmental protection the exogenous event about the supervision of law enforcement and achieves breakthroughs in empirical studies of administrative enforcement supervision. Second, the research pushes the studies on the implementation effect of environmental policies from a medium level to a micro level. Third, the research achieves some breakthroughs in the data for measuring corporate environmental performance.

Abstract

The relationship between stakeholders and organizations has been gaining more focus in strategic organizational management. The scenario of increased accountability required by society and by the competitive business environment itself demands ethical, fair, and sustainable practices from companies. In this sense, effective and fair stakeholder management becomes relevant. Thus, stakeholder theory proves to be a valid theoretical perspective for this challenge. In its conceptualization, stakeholder theory has pointed out different issues for strategic management practices, and how to treat the stakeholder fairly has been one of the concerns of the proponents of the theory (Bosse, Phillips, & Harrison, 2009). In this regard, principles of organizational justice have been incorporated into stakeholder management models. The authors argue that organizational justice, including its basic dimensions of distributive justice, procedural justice, and interactional justice, can positively impact the bottom line of organizations through synergy in value creation and by encouraging reciprocal behavior between the firm and stakeholders.

Abstract

Purpose

The purpose of this paper is to investigate the mediating effect of felt obligation for constructive change on the relationship between responsible leadership and organizational citizenship behavior for the environment (OCBE) in a China corporate environment, and this paper also analyze the moderated mediating effect of supervisor-subordinate guanxi on indirect relationship between responsible leadership and OCBE via felt obligation for constructive change.

Design/methodology/approach

This paper used 380 employee samples to analyze the relationship between responsible leadership and OCBE. Hierarchical regression analyses and structural equation modeling was adopted to analyze the data.

Findings

The authors found that the felt obligation for constructive change plays a fully mediating role between responsible leadership and OCBE. The authors also found a positive interaction between responsible leadership and supervisor-subordinate guanxi on felt obligation for constructive change, and then the indirect effect of responsible leadership on OCBE via felt obligation for constructive change was stronger when employees perceived a high-level supervisor-subordinate guanxi.

Research limitations/implications

When responsible leadership stimulates employees to generate a high sense of constructive change, employees are more likely to engage in OCBE. This study provides evidence for cognitive evaluation theory. This study further demonstrated the importance of establishing high-quality supervisor-subordinate guanxi for responsible leaders and subordinates in China.

Practical implications

In the management practice of the organization, the role of responsible leadership should be strengthened in terms of leadership development and, employee training and promotion, and high-quality supervisor-subordinate guanxi help to promote the effectiveness of responsible leadership.

Originality/value

This paper discusses how and when responsible leadership influences OCBE in a China corporate environment.

Abstract

Purpose

The vulnerability of multinational corporation (MNC) knowledge network is one of the major causes for the failure and even the death of MNCs in the fierce global market competition. Employee turnover and knowledge loss are the triggers for the MNC knowledge network vulnerability and a matter of serious concern in the evolution and development of MNC knowledge network. The purpose of this work is to propose a valid and quantitative measurement method to investigate the influence of employee loss and knowledge loss on the vulnerability of MNC knowledge network.

Design/methodology/approach

MNC knowledge network is inherently a heterogeneous network where there are mainly two types of units: employees and their knowledge. Therefore, this paper establishes a weighted super-network model for MNC knowledge network to depict its heterogeneous composition. On the basis of the weighted MNC knowledge super-network, the static and dynamic vulnerability measurement methods are further proposed to investigate and evaluate MNC knowledge network vulnerability.

Findings

A real case is given to illustrate the applicability of the proposed weighted MNC knowledge super-network model and the network vulnerability measurement methods. The results show the super-network model proposed in this paper can effectively embody the complex features of MNC knowledge network, and the vulnerability measurement methods can effectively investigate the influence of employee loss and knowledge loss on network vulnerability.

Originality/value

From the perspective of super-network, researchers and practitioners can get a more systematic and deeper understanding of the MNC knowledge network and its human and knowledge resource constitute which are vital for the evolution and development of MNC. Moreover, the MNC knowledge network vulnerability measurement methods can effectively measure and analyze the influence of resource loss on network vulnerability, which can provide a helpful decision support for monitoring and managing of MNC knowledge network vulnerability to reduce its adverse effects.

Purpose

The focus of industrial cluster innovation lies in the cooperation between enterprises and universities/scientific research institutes to make a theoretical breakthrough in the system and mechanism of industrial cluster network. Under the theoretical framework of cluster network, industrial structure can be optimized and upgraded, and enterprise benefit can be improved. Facing the increasing proliferation and multi-structured enterprise data, how to obtain potential and high-quality innovation features will determine the ability of industrial cluster network innovation, as well as the paper aims to discuss these issues.

Design/methodology/approach

Based on complex network theory and machine learning method, this paper constructs the structure of “three-layer coupling network” (TLCN), predicts the innovation features of industrial clusters and focuses on the theoretical basis of industrial cluster network innovation model. This paper comprehensively uses intelligent information processing technologies such as network parameters and neural network to predict and analyze the industrial cluster data.

Findings

From the analysis of the experimental results, the authors obtain five innovative features (policy strength, cooperation, research and development investment, centrality and geographical position) that help to improve the ability of industrial clusters, and give corresponding optimization strategy suggestions according to the result analysis.

Originality/value

Building a TLCN structure of industrial clusters. Exploring the innovation features of industrial clusters. Establishing the analysis paradigm of machine learning method to predict the innovation features of industrial clusters.

Abstract

Purpose

Drawing on the resource-based view, this study examines the effect of distribution adaptation on export performance. The study also examines the moderating role of responsiveness and commitment. Two distinct factors for commitment (i.e. managerial export commitment and financial export commitment) and two distinct factors for responsiveness (i.e. export customer responsiveness and export competitor responsiveness) are considered as moderators in the relationship between distribution adaptation and export performance.

Design/methodology/approach

Using a Spanish governmental database of exporting firms, this study collected data from 208 firms to run the analysis.

Findings

The results indicate that distribution adaptation has a positive impact on export performance. Findings also support the moderating roles of the two types of commitment and the two types of responsiveness. Managerial export commitment positively moderates the relationship, whereas financial export commitment plays a negative moderating role. Both export customer responsiveness and export competitor responsiveness have a positive moderating impact.

Originality/value

To consider distribution adaptation as a distinct variable rather than mixing it with other elements of the marketing mix. This distinction facilitates a clearer comprehension of its unique contribution to export performance. Two distinct factors for commitment and two distinct factors for responsiveness are considered. This approach offers a more detailed analysis of how the different aspects of commitment and responsiveness moderate this relationship.
