Purpose The purpose of this paper is to measure profitability and marketability efficiencies as well as examine the efficiencies’ determinants of listed manufacturing firms in Vietnam. Design/methodology/approach This study employs a bootstrap two-stage data envelopment analysis (DEA) approach to investigate the profitability and marketability efficiencies of 102 listed manufacturing firms on Vietnam stock market from 2007 to 2018. The study also applies fractional regression models (FRM) to identify the determinants of Vietnam manufacturing firms’ efficiencies. Findings The results reveal that Vietnam manufacturing firms obtain higher average profitability efficiency scores (0.888) than marketability efficiency scores (0.527) from 2007 to 2018. The high-tech firms achieve better profitability and marketability efficiencies than the traditional (resource-intensive and labour-intensive) Vietnam manufacturing firms in recent years (2016–2018). Further, the financial and non-financial factors have heterogeneous impacts on Vietnam manufacturing enterprises’ profit and market valuation efficiencies. Research limitations/implications Due to the nature of DEA technique that requires every decision-making unit to have available data of all inputs and outputs, the listed Vietnam manufacturing firms that have incomplete data or go public after 2007 are not included in the data set. Practical implications This study provides a reference for Vietnam manufacturing managers to position their firms competitively in the market as well as make wise operating, financing and management decisions. Originality/value This is the first study that attempts to combine bootstrap two-stage DEA and FRM, which are considered advantageous methods for DEA scores’ measurements and determinant evaluations in the current literature.

Purpose – Identification of the best school among other competitors is done using a new technique called most productive scale size based data envelopment analysis (DEA). The paper aims to discuss this issue. Design/methodology/approach – A non-central principal component analysis is used here to create a new plane according to the constant return to scale. This plane contains only ultimate performers. Findings – The new method has a complete discord with the results of CCR DEA. However, after incorporating the ultimate performers in the original data set this difference was eliminated. Practical implications – The proposed frontier provides a way to identify those DMUs which follow cost strategy proposed by Porter. Originality/value – A case study of six schools is incorporated here to identify the superior school and also to visualize gaps in their performances.

Purpose The purpose of this paper is to benchmark the operational and financial performances of the major Indian seaports to help derive useful insights to improve their performance. Design/methodology/approach A two-stage data envelopment analysis (DEA) methodology has been used with the help of data collected on the 13 major seaports of India. The first stage of the DEA captured the operational efficiencies, while the second stage the financial performance. Findings A window analysis over a period of three years revealed that no port was able to score an overall average efficiency of 100 per cent. The study identified the better performing units among their peers in both the stages. The contrasting results of the study with the traditional operational and financial performance measures used by the ports helped to derive useful insights. Research limitations/implications The data used in the study were majorly limited to the available sources in the public domain. Also, the study was limited to the major seaports which are under the Government of India and no comparisons were carried out with other local or international ports. Practical implications There is a need to prioritize investments and improvement efforts where they are most needed, instead of following a generalized approach. Once the benchmark ports are identified, the port authorities and other relevant stakeholders should work in detail on the factors causing inefficiencies, for possible improvements in performance. Originality/value This paper carried out a two-stage DEA that helped to derive useful insights on operational efficiency and financial performance of the India seaports. A combination of the financial and operational parameters, along with a comparison of the DEA results with the traditional measures, provided a different perspective on the Indian seaport performance. Considering the scarcity of research papers reported in the literature on DEA-based benchmarking studies of seaports in the Indian context, it has the potential to attract future research in this field.

Purpose – The purpose of this paper is to propose an economic cybernetics model based on the grey differential equation GM(1,N) for China's high-tech industries and provide the necessary support to assist high-tech industries management departments with their policy making. Design/methodology/approach – Based on the principle of grey differential equation GM(1,N), the grey differential equations of five high-tech industries in China are established using the net fixed assets, labor quantity and patent application quantity as cybernetics variables. After the discretization and first-order subtraction reduction to the simultaneous equation of the five grey models, a linear cybernetics model is resulted in. The structure parameters in the cybernetics system show explicit economic significance and can be identified through least square principle. At last, the actual data in 2004-2010 are introduced to empirically analyze the high-tech industrial system in China. Findings – The cybernetics system for China's high-tech industries are stable, observable, and controllable. On the whole, China's high-tech industries show higher output coefficients of the patent application quantity than those of net fixed assets and labor quantity. This suggests that China's industry development mainly depends on technological innovation rather than capital or labor inputs. It is expected that the total output value of China's high-tech industries will grow at an average annual rate of 15 percent in 2011-2015, with contributions of pharmaceuticals, aircraft and spacecraft, electronic and telecommunication equipments, computers and office equipments, medical equipments and meters by 21, 16, 13, 10, and 28 percent, respectively. In addition, pharmaceuticals, as well as medical equipments and meters, present upward proportions in the gross of Chinese high-tech industries significantly. Electronic and telecommunication equipments, plus computers and office equipments exhibit an obvious decreasing proportion. The proportion of the output value of aircraft and spacecraft is basically stable. Practical implications – Empirical analysis results are helpful for related management departments to formulate reasonable industrial policies to keep the sustained and stable development of the high-tech industries in China. Originality/value – Based on the grey differential equation GM(1,N), this research puts forward an economic cybernetics model for the high-tech industries in China. This model is applicable to the economic system with small sample data set.

Purpose The purpose of this paper is to predict the concrete pouring production rate by considering both construction and supply parameters, and by using a more stable learning method. Design/methodology/approach Unlike similar approaches, this paper considers not only construction site parameters, but also supply chain parameters. Machine learner fusion-regression (MLF-R) is used to predict the production rate of concrete pouring tasks. Findings MLF-R is used on a field database including 2,600 deliveries to 507 different locations. The proposed data set and the results are compared with ANN-Gaussian, ANN-Sigmoid and Adaboost.R2 (ANN-Gaussian). The results show better performance of MLF-R obtaining the least root mean square error (RMSE) compared with other methods. Moreover, the RMSEs derived from the predictions by MLF-R in some trials had the least standard deviation, indicating the stability of this approach among similar used approaches. Practical implications The size of the database used in this study is much larger than the size of databases used in previous studies. It helps authors draw their conclusions more confidently and introduce more generalised models that can be used in the ready-mixed concrete industry. Originality/value Introducing a more stable learning method for predicting the concrete pouring production rate helps not only construction parameters, but also traffic and supply chain parameters.

Purpose The purpose of this paper is automatic classification of TV series reviews based on generic categories. Design/methodology/approach What the authors mainly applied is using surrogate instead of specific roles or actors’ name in reviews to make reviews more generic. Besides, feature selection techniques and different kinds of classifiers are incorporated. Findings With roles’ and actors’ names replaced by generic tags, the experimental result showed that it can generalize well to agnostic TV series as compared with reviews keeping the original names. Research limitations/implications The model presented in this paper must be built on top of an already existed knowledge base like Baidu Encyclopedia. Such database takes lots of work. Practical implications Like in digital information supply chain, if reviews are part of the information to be transported or exchanged, then the model presented in this paper can help automatically identify individual review according to different requirements and help the information sharing. Originality/value One originality is that the authors proposed the surrogate-based approach to make reviews more generic. Besides, they also built a review data set of hot Chinese TV series, which includes eight generic category labels for each review.

Construction Contracting

PurposeThe purpose of this study is twofold: first, to identify major project management (PM) complexities in principal construction contracting; and second, to study the contribution of project management offices (PMOs) to addressing such complexities.Design/methodology/approachA two-stage research design was adopted through a structured literature review (SLR) and a qualitative survey study.FindingsThe two-stage study resulted in mapping out the contribution of 10 functional areas to 15 complexity factors that were retrieved from the literature and categorized using the TOE (technical, organizational and environmental) framework. Six outcomes including (1) facilitated processes, (2) improved decisions, (3) improved coordination, (4) enhanced alignment, (5) addressed uncertainties and (6) integrated oversight were identified that describe how PMOs can contribute to tackling complexities.Research limitations/implicationsSimilar to other qualitative studies, this study has some limitations in terms of the replicability of results. Regarding the exploratory nature of this study to explain the contribution of PMO to complexity, further quantitative surveys can be conducted using a larger sample to statistically examine the significance of proposed relations between capabilities and complexity factors.Practical implicationsThis study provides an understanding of the contribution of PMOs to tackling ever-increasing complexities embedded in construction contracting. The authors suggest requirements to be considered by professionals toward overcoming such complexities.Originality/valueAlthough prior studies have separately investigated PMO functions and PM complexities, this study explores the link between these two spheres to discuss one important application of PMO in this context.

Purpose The purpose of this paper is to examine the relationship between industry association membership and firm innovation in Chinese private ventures. A secondary objective is to investigate potential moderating effects of firm learning practices and founder characteristics on the above relationship, and to draw out implications for policymakers and practitioners. Design/methodology/approach The paper utilizes data from a sample of 567 Chinese entrepreneurial firms operating in 9 designated emerging industries. Hierarchical regression models were employed to analyze the effect of industry association membership on firm innovation, and the potential moderating effects. A 2SLS procedure was adopted to control for potential endogeneity issue. Supplemental analyses were conducted to ensure the robustness of the findings. Findings The paper provides empirical insights about how industry association membership, along with firm learning practice and founder leadership, affect firm innovation in Chinese private ventures in emerging industries. It suggests that industry association membership positively affects firm innovation. Further, there is a three-way interaction effect of industry association membership, learning practice and founder power on innovation. Research limitations/implications Due to the design of the data set, there are some limitations. First, the study only considered whether a firm belongs to an industry association, but not the nature of such membership (length, firm status in the association, etc.). Second, the cross-sectional design may limit the power of the study to make casual implications about the tested relationships. Practical implications The paper provides important practical implications for policymakers and entrepreneurs in China. In general, the results suggest that private ventures pursuing innovation in emerging industries can benefit from industry associations, and entrepreneurs shall actively engage in firm-level and personal-level learning. For policymakers, the study suggests that to foster innovation in an emerging industry, special attention shall be paid to building necessary institutional support to develop and to strengthen the role of industry association in the industry. Originality/value This paper fulfills an important gap in the literature in that it is one of the first, which investigates the role of the industry association in firm innovation, especially in a non-western context. This paper provides new insights into the role of industry association and firm innovation in an under-researched developing economy context.

The Impact

Purpose – The purpose of this paper is to present a yardstick efficiency comparison of 269 Indonesian municipal water utilities (MWUs) and measures the impact of exogenous environmental variables on efficiency scores. Design/methodology/approach – Two-stage Stackelberg leader-follower data envelopment analysis (DEA) and artificial neural networks (ANN) were employed. Findings – Given that serviceability was treated as the leader and profitability as the follower, the first and second stage DEA scores were 55 and 32 percent (0 percent = totally inefficient, 100 percent = perfectly efficient), respectively. This indicates sizeable opportunities for improvement, with 39 percent of the total sample facing serious problems in both first- and second-stage efficiencies. When profitability instead leads serviceability, this results in more decreased efficiency. The size of the population served was the most important exogenous environmental variable affecting DEA efficiency scores in both the first and second stages. Research limitations/implications – The present study was limited by the overly restrictive assumption that all MWUs operate at a constant-return-to-scale. Practical implications – These research findings will enable better management of the MWUs in question, allowing their current level of performance to be objectively compared with that of their peers, both in terms of scale and area of operation. These findings will also help the government prioritize assistance measures for MWUs that are suffering from acute performance gaps, and to devise a strategic national plan to revitalize Indonesia’s water sector. Originality/value – This paper enriches the body of knowledge by filling in knowledge gaps relating to benchmarking in Indonesia’s water industry, as well as in the application of ensemble two-stage DEA and ANN, which are still rare in the literature.

Purpose – The article aims to convey the experiences of installing an Espresso Book Machine (tm) into Windsor Public Library. It relates how an extremely high-tech, mechanical and new process was received in a very traditional field. Design/methodology/approach – Windsor Public Library acquired an Espresso Book Machine, and built around it a Self-Publishing Centre which included iMacs loaded with software, a scanner, a comfortable area and a dedicated staff member. Findings – The creativity that arose from the Self-Publishing Centre was not limited only to individual, solitary authors who wanted just to produce their own works. A network of like-minded people formed to give encouragement and support developed, increasing the opportunities for elevating literacy in our community. Research limitations/implications – Limitations are obviously that we are one small community enjoying the benefits of this machine. It is impossible to predict if other communities and geographic locations would enjoy the same success. Practical implications – Practical implications are that even with the advancing tide of ebooks and non-print matter, patrons are still very eager to consume and produce printed materials. Social implications – The technological marvels of the high-tech gear that have been installed would be lost without the people forming communities around the technology. Originality/value – The results of installing the Self-Publishing Centre were very different from what we anticipated. The products and community established here are as awe-inspiring as the machine at the heart of the Centre.
