Abstract
Purpose
Because of the rapid progress of global value chains (GVCs), it is worthwhile to study their impact on innovation. This study aims to explore the impact of GVC position of high-tech industries in the developing-country context of China on innovation performance; it also aims to explore the moderating effects of industrial agglomeration (specialization agglomeration and diversification agglomeration) on the relationship between GVC position and innovation performance.
Design/methodology/approach
The study is based on data gathered on Chinese high-tech industries in 30 provinces from the 2005–2015 period. The econometric analysis relies on merged data from the China Premium Database and the Trade in Value Added 2018 Database.
Findings
The regression results show that GVC position of China’s high-tech industries significantly affects their innovation performance, and both specialization agglomeration and diversification agglomeration significantly enhance the positive relationship between GVC position and innovation performance of China’s high-tech industries. After dividing the country into coastal and inland regions, new findings appear.
Originality/value
This study highlights the importance of GVC position and its effect on innovation performance of China’s high-tech industries. It contributes to the literature on the relationship between GVCs and innovation by elaborating on the moderating effects of industrial agglomeration on this relationship.

Abstract
Purpose
Although recent studies have increased attention on the effects of related and unrelated variety on innovation, a Chinese test has until now been missing from the literature. This paper aims to investigate how related and unrelated variety affect regional innovation in Chinese provinces. In particular, emphasis was placed on differentiating the analysis for the industry and services sectors at a detailed sectoral level.
Design/methodology/approach
This paper’s sample is composed of 30 provinces in China from 2003 to 2016. Feasible generalized least squares was used to estimate the effects of related and unrelated variety on regional innovation.
Findings
The results show that related variety in all sectors promotes regional innovation, whereas unrelated variety in all sectors does not play a role. In-depth analyses were performed by comparing the industry and services sectors. Only related variety in the industry sector and unrelated variety in the services sector promote regional innovation, whereas unrelated variety in the industry sector exerts a negative effect. After dividing the country into eastern, central and western regions, different findings appear in the sub-samples.
Originality/value
This study contributes to the literature on evolutionary economic geography and innovation by exploring how related and unrelated variety promote regional innovation in a developing country context (China). It also sheds light on the sectoral and regional differences in the influence of related and unrelated variety on regional innovation.

Abstract
Purpose
Digital multimodal composing (DMC) has received considerable attention in English as a Foreign Language (EFL) classrooms. While empirical studies on DMC have been widely conducted, there is a scarcity of research specifically examining the experience of pre-service English teachers in employing DMC during their teaching practicum. They might be familiar with DMC concepts, yet their beliefs about implementing DMC-mediated language teaching in classroom settings is worth further investigation. To fill this gap, this study aims to investigate the perspectives of three pre-service English teachers on DMC-mediated language teaching during their teaching practicum program.
Design/methodology/approach
This study employed a case study design and was conducted in a state Islamic university in East Java Province, Indonesia. A semi-structured interview was conducted with three pre-service English teachers to collect data about the beliefs of pre-service English teachers in implementing DMC in their teaching practicum. Data were analyzed through thematic analysis.
Findings
From the analysis, the study unveils three important findings: (1) pre-service teachers' awareness of implementing DMC in English classrooms, (2) pre-service teachers' pedagogical preference for DMC projects and (3) pre-service teachers' perceived challenges in teaching through DMC.
Originality/value
The study suggests that equipping pre-service teachers with adequate pedagogical competence in DMC will enhance their capacity for technological pedagogical and content knowledge (TPACK).

Abstract
Purpose
This paper aims to propose a novel multiple transient modeling scheme for the 12-pulse phase-shifting reactor (PSR) rectifier to enhance the efficiency of full-cycle design evaluation.
Design/methodology/approach
The detailed time-domain method is adopted to model the rectifier at the behavioral layer. The diode bridges/transformer model at the architecture layer is established by using the switch function and Park transformation. The frequency domain model at the functional layer is derived with the time-varying Fourier decomposition and frequency-shifting. At the component layer, the magneto-thermal characteristics of the rectifier are analyzed with field-circuit and magnetic-thermal coupling methods. A computer-aided design program integrating multiple modeling is also developed for industrial product design.
Findings
The function layer modeling is preferred in the initial design stage, making up for the lack of modeling accuracy at the architectural layer and the lack of modeling rapidity at the behavioral layer. The component modeling is irreplaceable for the detailed evaluation in the latter design stage. The multiple modeling scheme based on the four-layer modeling helps the designers achieve high-quality products with a short development cycle.
Originality/value
The singular transient modeling cannot cover the needs of different stages in the full-cycle design evaluation. This paper fills this gap with a novel multiple modeling scheme. Meanwhile, the proposed multiple modeling scheme and developed computer-aided design program provide a great convenience for full cycle design evaluation of the 12-pulse PSR rectifier.

Abstract
Purpose
This study aims to focus on the optimal green R&D of a capital-constrained supply chain under different channel power structures as well as the impact of capital constraint, financing cost, channel power structure and cost-reducing efficiency on green R&D and supply chain profitability.
Design/methodology/approach
A two-echelon supply chain is considered. The upstream firm engages in green R&D but has capital constraints that can be overcome by external financing. Green R&D is beneficial to reduce production costs and increase consumer demand. Based on whether or not the upstream firm is capital constrained and dominates the supply chain, four models are developed.
Findings
Capital constraints significantly lower green R&D and supply chain profitability. Transferring leadership from the upstream to the downstream firms leads to higher green R&D levels and downstream firm profitability, whereas the upstream firm's profitability is increased (decreased) if green R&D investment efficiency is high (low) enough. Greater financing costs reduce green R&D and downstream firm profitability; however, the upstream firm's profitability under the model in which it functions as the follower increases if the initial capital is sufficient. More importantly, empirical analysis based on practice data is used to verify the theoretical results reported above.
Practical implications
This study reveals how upstream firms in supply chains decide green R&D decisions in situations with capital constraints, providing managers and governments with an understanding of the impact of capital constraint, channel power structure, financing cost and cost-reducing efficiency on supply chain green R&D and profitability.
Originality/value
The major contributions are the exploration of supply chain green R&D by taking into consideration channel power structures and cost-reducing efficiency and the validation of theoretical results using practice data.

Abstract
Purpose
This study aims to examine the direct impact of internal green supply chain practices (IGSCP) on green human resource management (GHRM), supply chain environmental cooperation (SCEC) and firm performance (FP). The mediating influences of GHRM and SCEC on the influence of IGSCP on FP are also examined. The study further examines the mediating influence of SCEC on the link between GHRM and FP.
Design/methodology/approach
The study uses a quantitative method where data is gathered from human resource and supply chain managers of 139 manufacturing firms (food, beverage and alcohol, textiles, agrochemical and plastics), using customized questionnaires. The data is analyzed using the partial least square structural equation modeling software (SmartPLS 3.2.8).
Findings
The results suggest that the adoption of only IGSCP may negatively affect the market and financial performances of firms. However, the implementation of GHRM and SCEC may catalyze IGSCP to improve FP.
Originality/value
The study develops a comprehensive empirical model that tests the joint influence of internal green supply chain, GHRM and SCEC on FP. The findings indicate that IGSCP, GHRM and SCEC help firms to advance FP.

Abstract
Purpose
The link between corruption and firm performance has received considerable critical attention. However, until now, far too little attention has been paid to different dimensions of corruption and their relationship with firm performance. The aim of this paper is, therefore, to examine the relationship between dimensions of corruption and firm productivity.
Design/methodology/approach
This paper uses the fifth wave of Business Environment and Enterprise Performance Survey, which is based on the survey questionnaire with senior managers of 16,566 randomly selected firms across 32 developing countries. Empirical analysis employs structural equation modeling (SEM) and instrumental variable two-stage least square (IV 2SLS) estimation techniques.
Findings
Our results revealed that political corruption and red tape have a positive relationship with firm productivity. We also found that perceived extent of bribe and corruption experience are positively related to the firm productivity.
Practical implications
Findings suggest that multifaceted dimensions of corruption exist. Therefore, policymakers should develop anticorruption measures by taking into account these dimensions. In addition, policymakers should focus on improving institutional quality by reforming laws and measures to detect and punish government officials.
Originality/value
So far only few studies have looked at the dimensions of corruption; therefore, this study seeks to examine the effect of different dimensions of corruption together on firm performance in postcommunist countries.

Abstract
Purpose
This paper aims to consider both the greenhouse gas (GHG) emissions and behavioural response in the optimal sizing of solar photovoltaic systems (PV modules and batteries) for energy communities. The objective is to achieve a high self-sufficiency rate whilst taking into account the grid carbon intensity and the global warming potential of system components.
Design/methodology/approach
Operation and sizing of energy communities leads to optimization problems spanning across multiple timescales. To compute the optimisation in a reasonable time, the authors first apply a simulation periods reduction using a clustering approach, before solving a linear programming problem.
Findings
The results show that the minimum GHG emissions is achieved for self-sufficiency rates of 19% in France and 50% in Germany.
Research limitations/implications
The analysis is restricted to specific residential profiles: further work will focus on exploring different types of consumption profiles.
Practical implications
This paper provides relevant self-sufficiency orders of magnitude for energy communities.
Originality/value
This paper combines various approaches in a single use case: environmental considerations, behavioural response as well as multi-year energy system sizing.

Abstract
Purpose
The efficiency of each of an organization’s individual workers determines its effectiveness. The study aims to explore the relationship between human resource management (HRM) practices and organizational effectiveness with employee performance as a mediating variable.
Design/methodology/approach
Data were collected from 800 police officers in the Greater Accra and Tema regions. The data were supported by the hypothesized relationship. Construct reliability and validity was established through confirmatory factor analysis. The proposed model and hypotheses were evaluated using structural equation modeling.
Findings
The results show that career planning and employee performance were significantly related. Self-managed teams and employee performance were shown to be nonsignificantly related. Similarly, performance management and employee performance were shown to be nonsignificantly related. Employee performance significantly influenced organizational effectiveness. The results further indicate that employee performance mediates the relationship between HRM practices and organizational effectiveness.
Research limitations/implications
The generalizability of the findings will be constrained due to the research’s police service focus and cross-sectional data.
Practical implications
The study’s findings will serve as valuable pointers for the police administration in the adoption, design and implementation of well-articulated and proactive HRM practices to improve the abilities, skills, knowledge and motivation of officer’s to inordinately enhance the effectiveness of the service.
Originality/value
By evidencing empirically that employee performance mediates the relationship between HRM practice and organizational effectiveness, the study extends the literature.
