Abstract
Purpose
Vertical electrical sounding (VES) and Rayleigh wave exploration are widely used in the exploration of near-surface structure, but both have limitations. This study aims to make full use of the advantages of the two methods, reduce the multiple solutions of single inversion and improve the accuracy of the inversion. Thus, a nonlinear joint inversion method of VES and Rayleigh wave exploration based on improved differential evolution (DE) algorithm was proposed.
Design/methodology/approach
Based on the DE algorithm, a new initialization strategy was proposed. Then, taking AK-type with high-velocity interlayer model and HA-type with low-velocity interlayer model near the surface as examples, the inversion results of different methods were compared and analyzed. Then, the proposed method was applied to the field data in Chengde, Hebei Province, China. The stratum structure was accurately depicted and verified by drilling.
Findings
The synthetic data and field data results showed that the joint inversion of VES and Rayleigh wave data based on the improved DE algorithm can effectively improve the interpretation accuracy of the single-method inversion and had strong stability and large generalizable ability in near-surface engineering problems.
Originality/value
A joint inversion method of VES and Rayleigh wave data based on improved DE algorithm is proposed, which can improve the accuracy of single-method inversion.

Abstract
Purpose
We aim to comb the current policies that have been developed to promote the environmental industries in China and analyze them in a comparative manner.
Methodology/approach
We mainly use the method of text study to study the existing policies that Chinese central government published to promote the development of environmental industry. We built a database of policies and regulations from 1979 to 2015 by searching the official website of the Ministry of Environmental Protection of China.
Findings
We find that the existing policies focus on command and control approaches. Policies are more oriented to the stage of production instead of stages of investment and consumption. They rely more on negative incentive when stimulating supply and positive incentive when encouraging demand. Based on existing academic wisdom, we suggest that Chinese government should pay more attention to environmental economic policy and to stimulating demand for environmental products.
Originality/value
Few studies provide a systematic overview of the policy systems that have been developed to promote environmental industry in China in a systematic manner.

Abstract
Purpose
Open innovation enables firms to incorporate external expertise and resources into their innovations. However, it is far from easy to obtain sufficient support from external contributors due to potential concerns about the risks of opportunism and appropriation. This paper aims to investigate whether firms’ engagement in corporate social responsibility (CSR) contributes to their open innovation, considering the contingency factors of technological capability, environmental dynamism and state ownership based on capability and motivation perspectives.
Design/methodology/approach
Using a sample of Chinese listed firms covering the period from 2009 to 2018, instrumental variable and propensity score matching approaches were used to address the endogenous problems.
Findings
This paper obtains empirical results showing that firms engaged in higher levels of CSR produce more joint outputs (co-owned patents) and that this effect is strengthened by technological capability and environmental dynamism. Among state-owned enterprises, CSR engagement is less impactful with regard to open innovation. It is further shown that open innovation is a primary channel through which CSR engagement enhances innovative efficiency.
Originality/value
This study enriches the knowledge of the antecedents of open innovation and contributes to the debate regarding the relationship between CSR and innovation by establishing a relationship between CSR and open innovation, whereas most prior studies focus on how the input and output of innovation are affected by CSR initiatives.

Abstract
Purpose
Research on grey systems is becoming more sophisticated, and grey relational and prediction analyses are receiving close review worldwide. Particularly, the application of grey systems in marine economics is gaining importance. The purpose of this paper is to summarize and review literature on grey models, providing new directions in their application in the marine economy.
Design/methodology/approach
This paper organized seminal studies on grey systems published by Chinese core journal database – CNKI, Web of Science and Elsevier from 1982 to 2018. After searching the aforementioned database for the said duration, the authors used the CiteSpace visualization tools to analyze them.
Findings
The authors sorted the studies according to their countries/regions, institutions, keywords and categories using the CiteSpace tool; analyzed current research characteristics on grey models; and discussed their possible applications in marine businesses, economy, scientific research and education, marine environment and disasters. Finally, the authors pointed out the development trend of grey models.
Originality/value
Although researches are combining grey theory with fractals, neural networks, fuzzy theory and other methods, the applications, in terms of scope, have still not met the demand. With the increasingly in-depth research in marine economics and management, international marine economic research has entered a new period of development. Grey theory will certainly attract scholars’ attention, and its role in marine economy and management will gain considerable significance.

Abstract
Purpose
The authors position security measures and payment culture as key determinants of perceived security (PS) and trust. The purpose of this paper is to empirically investigate how PS and trust affect users’ attitude toward mobile payment use and why mobile payment has developed differently in the USA and in China.
Design/methodology/approach
Empirical data were collected from a survey conducted both in China and in the USA. The whole sample consists of 186 Chinese and 196 Americans. Partial least squares analysis was conducted to test the proposed relationships and multigroup comparison analysis was performed to examine the differences in the coefficients of those relationships between Chinese and the US model.
Findings
The findings show that payment culture (measured by coverage of mobile payment context (CMPC) and uncertainty avoidance (UA)) and security measures (measured by security technology protection (STP), security rules and policies (SRP), and security responsibility commitment (SRC)) have significantly positive impacts on the PS and trust, except that the positive impact of security on trust is not supported. The impacts of CMPC and PS on trust in the USA are significantly smaller than those in China, whereas the impacts of security measures and UA on PS and trust do not show significant differences between the two countries.
Research limitations/implications
Respondents of this study are selected from young educated population, the major users of mobile payment in 2015. However, recently with the increasing penetration of mobile payment, major mobile payment users are not only limited to young educated population, and thus there may be new findings after extending the range of respondents’ age. Since the research subjects in this study are the mobile payment of China and the USA, the authors could also expect different findings when the research subjects are extended or changed to other countries because of different mobile payment cultures across countries.
Practical implications
Findings in this paper will help mobile payment service providers to know the determinants of their users’ behavior intention and to take measures to improve these determinants, and these findings can also provide mobile payment service providers with insights into the differences in mobile payment use between the two countries and suggestions of measures that they can take to increase users’ attitude toward mobile payment use. Furthermore, the findings of this paper also help these providers globalize efficiently by paying more attention to those antecedents.
Social implications
The findings in this paper show that there is no difference in the impacts of UA and security measures on PS and trust between China and the USA. However, the impacts of PS and CMPC on trust in China are significantly higher than those in the USA. This is because that globalization has made people from different countries hold similar UA, whereas the CMPC, a construct refers to the business environment of mobile payment, is still very different between China and the USA.
Originality/value
This study extends prior studies of attitude toward mobile payment use through proposing that security measures and payment culture are key determinants of PS and trust and examining the role of PS and trust on the attitude. Furthermore, the empirical findings will not only provide mobile payment service providers with important insights into the differences in mobile payment adoption between the two countries, but also help these providers globalize efficiently by paying more attention to those antecedents.

Abstract
Purpose
Taking the lens of a cue diagnosticity framework and affective primacy theory, this study aims to examine the relative effects of cognitive and affective country image on consumer cognitive judgement, affective evaluation and behavioural tendency in one integrated model. It also explores how the direct effects may vary with the intra-valence nature (ambivalent vs. univalent) of cognition-affect.
Design/methodology/approach
The proposed research model was tested using data from a large Chinese sample and consumer responses to products from four countries − the USA, Japan, Brazil and India.
Findings
The results show that the relative effects of cognitive and affective country image are complex and differ by the intra-valence nature of cognition-affect. On a general level, cognitive and affective country image exert equal influence on affective evaluation and behavioural tendency. In contrast, cognitive country image demonstrates a more prominent effect than affective country image on cognitive judgement. Compared with univalent, ambivalent cognition-affect strengthens the positive impact of affective country image but does not significantly alter the positive impact of cognitive country image on consumer reactions.
Originality/value
This research contributes to the ongoing debate regarding implications of two focal aspects of macro country image by revealing their relative importance in an integrated framework and enriches country-of-origin research through unveiling the uni/ambivalent cognition-affect as a moderator of the relationship between cognitive/affective country image and consumer reactions. The research findings provide implications as to whether and when marketing strategies should focus on leveraging positive (negative) cognitive or affective country image.

Abstract
Purpose
This study, based on construal level theory, aims to examine the influential mechanism of leader empowerment behaviour on employee creativity. Specifically, it examines the mediating role of cognitive flexibility between leader empowerment behaviour and employee creativity, along with the moderating effect of consideration of future consequences (CFC) on this linkage.
Design/methodology/approach
A two time-point survey study (n = 214) was conducted to collect information from leaders and employees in terms of mutual evaluation in several Chinese industries. To effectively avoid common source bias, this survey was conducted through pairing leaders and employees. During the survey, the supervisors and subordinates were double-blinded. Correlation analysis and hierarchical regression analysis were used to test the research hypotheses.
Findings
Firstly, leader empowerment behaviour can significantly predict employee creativity. Second, cognitive flexibility plays a partial mediating role in the linkage between leader empowerment behaviour and employee creativity. Thirdly, CFC moderates the relationship between leadership empowerment behaviour and cognitive flexibility. The mediating role of cognitive flexibility underlies the overall moderating effect of CFC on the relationship between leader empowerment behaviour and employee creativity.
Research limitations/implications
We used construal level theory to explain the influence of the mechanism of leader empowerment behaviour on employee creativity. In this manner, this study bridges the gap between theory and practice, as well as enriching the research on leader empowerment behaviour and employee creativity, especially in the Chinese context. Moreover, our study has several practical managerial implications, based on the importance of employee creativity. It inspires the implementation of leader empowerment behaviour, cultivation of employee creativity and introduction of several procedures.
Originality/value
This paper discusses the influential mechanism of leader empowerment behaviour on employee creativity from a new perspective and explains the process of encouraging employee creativity through information-processing methods. It mainly highlights the application of construal level theory to discuss employee creativity and develops a new research frame for employee creativity. Leaders can raise employee creativity through leader empowerment behaviour.

Abstract
Purpose
To present the mechanism, on which the first module was successfully designed – the automated installation application system, in the grand automated management and evaluation for community health service (CHS) sector of China.
Design/methodology/approach
The automated installation application system is constructed on the platform of Visual FoxPro8.0. The construction consists of five steps. The first is to establish the “item.” The function of “the item” is to trace all procedures, forms, menus, and various databases, such as tabulated data, summary data, and other types of data. The second is to establish the customer log‐in module. This module needs to contain a roll book of authorized customers. The third is to construct the subsystem management interface. This interface includes: entering installation the application, modifying and saving and transferring out the information, searching, printing blank form and statement. The fourth is to establish a roll book of all forms and the database of all the forms. The fifth is to establish the main procedure, connecting all the modules in the working order.
Findings
The main advantage of the system is that it is helpful for the characteristics of speedy information importation, clear and straight to the point, as well as the secure and accurate data transfer.
Originality/value
Automated management and evaluation for CHS heavily depends on the initial activation and this initiation is started using the system of installation application.

Abstract
Purpose
Considering the small sample size and non-linear characteristics of historical energy consumption data from certain provinces in Southwest China, the authors propose a hybrid accumulation operator and a hybrid accumulation grey univariate model as a more accurate and reliable methodology for forecasting energy consumption. This method can provide valuable decision-making support for policy makers involved in energy management and planning.
Design/methodology/approach
The hybrid accumulation operator is proposed by linearly combining the fractional-order accumulation operator and the new information priority accumulation. The new operator is then used to build a new grey system model, named the hybrid accumulation grey model (HAGM). An optimization algorithm based on the JAYA optimizer is then designed to solve the non-linear parameters θ, r, and γ of the proposed model. Four different types of curves are used to verify the prediction performance of the model for data series with completely different trends. Finally, the prediction performance of the model is applied to forecast the total energy consumption of Southwest Provinces in China using the real world data sets from 2010 to 2020.
Findings
The proposed HAGM is a general formulation of existing grey system models, including the fractional-order accumulation and new information priority accumulation. Results from the validation cases and real-world cases on forecasting the total energy consumption of Southwest Provinces in China illustrate that the proposed model outperforms the other seven models based on different modelling methods.
Research limitations/implications
The HAGM is used to forecast the total energy consumption of the Southwest Provinces of China from 2010 to 2020. The results indicate that the HAGM with HA has higher prediction accuracy and broader applicability than the seven comparative models, demonstrating its potential for use in the energy field.
Practical implications
The HAGM(1,1) is used to predict energy consumption of Southwest Provinces in China with the raw data from 2010 to 2020. The HAGM(1,1) with HA has higher prediction accuracy and wider applicability compared with some existing models, implying its high potential to be used in energy field.
Originality/value
Theoretically, this paper presents, for the first time, a hybrid accumulation grey univariate model based on a new hybrid accumulation operator. In terms of application, this work provides a new method for accurate forecasting of the total energy consumption for southwest provinces in China.
