Abstract

Purpose

The purpose of this paper is to analyze and estimate the stray current corrosion hazard of a buried metallic pipeline using a predictive model for stray current density.

Design/methodology/approach

A predictive model for stray current density of the buried metallic pipeline was built, using a back propagation (BP) neural network method and experimental data. The accuracy of the model was tested using test samples. The single sensitivity analysis predictive method was used to establish the relationship between stray current density with the soil resistivity. The effects of buried depth and the pipe‐to‐ground voltage offset were researched using this network model.

Findings

The feasibility of the BP neural network to forecast stray current effects from the buried metallic pipeline was confirmed.

Originality/value

The paper provides a new method to analyze and estimate the stray current corrosion hazard of buried metallic pipelines.

Abstract

Purpose

This paper aims to explore the functionality of long tail markets (LTM), where the consumers cannot be reached or are ignored by the traditional mainstream businesses, in new products and business development.

Design/methodology/approach

First, the authors review two Chinese entrepreneurial practices in the Fintech sector and low-speed electric vehicles (LSEV) and describe their stylized facts; second, they explore a possible theoretical LTM framework to underscore these practices; third, they make a connection between LTM and existing business models and analyze its significance and practical implications in business, in particular, in developing economies.

Findings

The LTM business approach has helped Chinese companies in the Fintech sector and LSEVs gain global attention. The success factors of LTM for businesses are identifying a specific customer base, being aware of localization products and playing skillfully with regulations; the LTM approach has several overlaps with existing studies on niche products and base of the pyramid market.

Originality/value

Based on some emerging and attractive business practices in China, this paper offers a valuable attempt to theorize them as long tail phenomenon. The LTM thesis provides a potential framework to reference for similar methods elsewhere and may illuminate entrepreneurship to be explored in similar markets.

Abstract

Purpose

The purpose of this paper is to investigate the economic relationship with recent changes in China’s land use policy and rural development through innovation and entrepreneurship.

Design/methodology/approach

The first issue of economic importance is in understanding the market value of land use rights (LUR) transactions. To examine this, the authors build an argument around the idea of economic and marginal rents from Ricardo. The second issue relates to the extent by which deepening the rural financial landscape by allowing the mortgaging of LUR will promote and advance much needed entrepreneurial activity. To explore this issue, the authors draw on Schumpeter. The empirical contribution is based on a survey of 1,465 farm households in Gansu, Henan, Shaanxi and Shandong provinces.

Findings

In an endogenous Two-Stage Least Squares model, the authors find a positive and significant relationship between a willingness to mortgage LUR and entrepreneurship, which suggest that the new policy may well meet that objective. However, the authors do not find that entrepreneurs alone will have a willingness to mortgage LUR; non-entrepreneurs – traditional farmer types – would also be willing to mortgage LUR, but with a caveat that either group already has a disposition or demand for credit.

Originality/value

The value of the analysis is to provide an evidence to understand the market value of LUR transactions and to study the relationship between mortgage of LUR and entrepreneurial activity.

Abstract

Purpose

To cope with the severe situation of the global climate, China proposed the “30 60” dual-carbon strategic goal. Based on this background, the purpose of this paper is to investigate scientifically and reasonably the interprovincial pattern of China’s power carbon emission intensity and further explore the causes of differences on this basis.

Design/methodology/approach

Considering the principle of “shared but differentiated responsibilities,” this study measures the carbon emissions within the power industry from 1997 to 2019 scientifically, via the panel data of 30 provinces in China. The power carbon emission intensity is chosen as the indicator. Using the Dagum Gini coefficient to explore regional differences and their causes.

Findings

The results of this paper show that, first, China’s carbon emission intensity from the power industry overall is significantly different. From the perspective of geospatial distribution, the three regions have unbalanced characteristics. Second, according to the decomposition results of the Gini coefficient, the overall difference in power carbon emission intensity is generally expanding. The geospatial and economic development levels are examined separately. The gaps between the eastern and economically developed regions are the smallest, and the regional differences are the source of the overall disparity.

Research limitations/implications

Further exploring the causes of differences on this basis is crucial for relevant departments to formulate differentiated energy conservation and emission reduction policies. This study provides direction for analyzing the green and low carbon development of China’s power industry.

Practical implications

As an economic indicator of green and low-carbon development, CO2 intensity of power industry can directly reflect the dependence of economic growth on the high emission of electricity and energy. and further exploring the causes of differences on this basis is crucial for relevant departments to formulate differentiated energy conservation and emission reduction policies.

Social implications

For a long time, with the rapid economic development, resulting in the unresolved contradiction between low energy efficiency and high carbon emissions. To this end, scientifically and reasonably investigating the interprovincial pattern of China’s power carbon emission intensity, and further exploring the causes of differences on this basis, is crucial for relevant departments to formulate differentiated energy conservation and emission reduction policies.

Originality/value

Third, considering the influence of spatial factors on the convergence of power carbon emission intensity, a variety of different spatial weight matrices are selected. Based on the β-convergence theory from both absolute and conditional perspectives, we dig deeper into the spatial convergence of electricity carbon emission intensity across the country and the three regions.

Abstract

Purpose

The rising uncertainties in the macroeconomic environment exacerbate the challenges firms face in the export market. This study aims to explore which strategy is suitable for export enterprises to develop sustainably under COVID-19.

Design/methodology/approach

Based on the sample data of China’s A-stock listed manufacturing firms from 2010 to 2020, this study applies a survival analysis method to explore the impact of strategic flexibility on export firm survival. Furthermore, this study uses the difference-in-difference model to test the relationship between strategic flexibility and firms’ profits in the context of the pandemic.

Findings

The results show that strategic flexibility can increase firms’ survival time, improving dynamic production and innovation capabilities, which is favorable for their sustainable development. Meanwhile, after the spread of COVID-19, firms with strategic flexibility have higher profits than those without. This influence mechanism mainly involves exploring new markets that can improve the company revenue and the coordination capabilities of the supply chain; this reduces corporate costs.

Originality/value

This study expands relevant research on the factors affecting the survival of export enterprises and supplements research on the economic consequences of firms’ strategic flexibility; this also enriches the dynamic capability theory. Additionally, it provides important implications for firms to enhance strategic flexibility and recommends government implementation of policies that encourage the domestic sales of commodities originally produced for exports under COVID-19.

Abstract

Purpose

The aim of this study is to explore, identify and understand the impact of technology affordance in the context of social networking sites (SNSs). Moreover, this study incorporates user experience as a moderator, in order to explore behavioral differences between veterans (high-experience users) and newbies (low-experience users).

Design/methodology/approach

A research model was developed to examine the influences of three technology affordances: interactivity, information and navigation on user satisfaction and SNS stickiness. Totally 266 data were collected from a famous college in China using an online survey, and structural equation modeling technique was used to examine the proposed research model.

Findings

The empirical research findings indicated that the three technology affordance attributes exhibited different degrees of influence on user satisfaction, which in turn facilitated SNS stickiness. Particularly, high-experience users were more likely influenced by interactivity and information affordances, while low-experience users are more susceptible to navigation affordance.

Practical implications

This study can provide guidelines to the platform administrators to design SNSs from the aspects of interactivity, information and navigation attributes and pay attention to the preference differences between high-experience users and low-experience users.

Originality/value

This study uncovers the significant antecedents of SNS stickiness from a technology affordance lens and reveals the moderating effect of user experience on the relationship between three technology affordance attributes and satisfaction.

Abstract

Purpose

The efficient market hypothesis (EMH) states that asset prices in financial markets always reflect all available information about economic fundamentals. The purpose of this paper is to provide a guide as to which predictions of the EMH seem to be borne out by empirical evidence.

Design/methodology/approach

Rather than following the classic three groups of tests for the different forms of EMH that are common in the literature, the authors consider how the two alternative definitions of the EMH and the joint hypothesis problem impact on the tests and leave the controversy unsolved. The authors briefly report the antecedents, the main theoretical and empirical contributions and recent literature on each type of tests.

Findings

Eventually, as a summary for each type of tests, the authors provide a critical view on the main sources of acrimony between the alternative schools of thought in understanding asset price formation.

Originality/value

The paper may be seen as an up-to-date introductory review for researchers on the different tests of the EMH performed, and for newcomers to understand the key sources of acrimony between rationalists and behaviorists.

Abstract

Purpose

Compared with traditional methods relying on manual teaching or system modeling, data-driven learning methods, such as deep reinforcement learning and imitation learning, show more promising potential to cope with the challenges brought by increasingly complex tasks and environments, which have become the hot research topic in the field of robot skill learning. However, the contradiction between the difficulty of collecting robot–environment interaction data and the low data efficiency causes all these methods to face a serious data dilemma, which has become one of the key issues restricting their development. Therefore, this paper aims to comprehensively sort out and analyze the cause and solutions for the data dilemma in robot skill learning.

Design/methodology/approach

First, this review analyzes the causes of the data dilemma based on the classification and comparison of data-driven methods for robot skill learning; Then, the existing methods used to solve the data dilemma are introduced in detail. Finally, this review discusses the remaining open challenges and promising research topics for solving the data dilemma in the future.

Findings

This review shows that simulation–reality combination, state representation learning and knowledge sharing are crucial for overcoming the data dilemma of robot skill learning.

Originality/value

To the best of the authors’ knowledge, there are no surveys that systematically and comprehensively sort out and analyze the data dilemma in robot skill learning in the existing literature. It is hoped that this review can be helpful to better address the data dilemma in robot skill learning in the future.

Abstract

Purpose

Manufacturing firms face increasing pressure to be more “greener” or environmentally friendly. Drawing upon the sustainable development (SD) theory and resource-based view, this study aims to examine the role of total quality management (TQM) and its effect on corporate SD (CSD). Also, this study focused on the mediating role of green innovation (GI).

Design/methodology/approach

This study used data from a time-lagged design with two waves that strengthened the hypothesized framework and used structural equation modeling to test the hypotheses.

Findings

The results showed a significant influence of TQM on CSD and GI. Also, GI positively affects CSD and fully mediates TQM and CSD relationships.

Practical implications

Important practical implications are integrating the quality indicators with sustainability and environmental dimensions. This study shall help the managers and policymakers in achieving their sustainability goals.

Originality/value

This study advances the prior literature and provides a noble approach of SD for TQM in manufacturing small and medium enterprises in an emerging country context.

Abstract

Purpose

The ever-demanding role of employees in the hospitality sector stimulates job crafting. This study examines the relationship between inclusive leadership and job-crafting dimensions under the mediating role of work engagement through the lens of conservation of resources (COR) theory. It also aims to analyse the boundary condition of job autonomy between inclusive leadership and work engagement.

Design/methodology/approach

The data were collected in 3-time lags from 319 front-line workers in the hospitality sector. The adopted and adapted questionnaires were executed through a deductive approach and an applied research method. The data were analysed through SmartPLS by applying the structural equation modelling (SEM) technique.

Findings

This study provides evidence for a predictive relationship between inclusive leadership and job-crafting dimensions under the mediating psychological mechanism of work engagement. Additionally, the moderating role of job autonomy is established in the unique context of the hospitality sector of an underdeveloped country, Pakistan.

Practical implications

Services-based organisations need to endure the inclusive leadership style by establishing work engagement practices. Engaged employees result in better job-crafting behaviours through better training and subsequent performance.

Originality/value

This study established that work engagement and job autonomy are imperative forces that impact the relationship between inclusive leadership and job-crafting dimensions. The research study has time-lagged data and conveys meaningful theoretical and practical implications.
