Abstract
Purpose
Sharing resources with stakeholders is the key for keystones to govern business ecosystems successfully. However, existing research has not paid further attention to how keystones share resources under the condition of resource sufficiency and how keystones balance resource sharing with complementors when they lack resources. Therefore, this paper aims to explore how keystones govern their business ecosystems under the conditions of resource sufficiency and resource insufficiency.
Design/methodology/approach
This paper adopts the single case study method. First, by adopting Gioia coding to analyze the relevant data of the case sample, this paper obtains the key concepts of the business ecosystem governance process. Then, it establishes the relationship between the concepts by analyzing the governance process of the case sample.
Findings
Under the condition of resource sufficiency, keystones under the condition of resource sufficiency, should make full use of resources to incubate more complementors, and further integrate the resources of the business ecosystem, to create more value for their business ecosystems. Under the condition of resource insufficiency, keystones should break the boundaries of business ecosystems and acquire external resources, to meet the resource needs of complementors. Subsequently, keystones should redeploy idle resources according to the actual needs of complementors, to meet the changing resource needs of complementors.
Originality/value
This study subdivides business ecosystem governance conditions and further constructs the business ecosystem governance process model, which provides a theoretical and practical reference for business ecosystem governance.

Abstract
Purpose
The purpose of this study is to simultaneously determine the constitutive parameters and boundary conditions by solving inverse mechanical problems of power hardening elastoplastic materials in three-dimensional geometries.
Design/methodology/approach
The power hardening elastoplastic problem is solved by the complex variable finite element method in software ABAQUS, based on a three-dimensional complex stress element using user-defined element subroutine. The complex-variable-differentiation method is introduced and used to accurately calculate the sensitivity coefficients in the multiple parameters identification method, and the Levenberg–Marquardt algorithm is applied to carry out the inversion.
Findings
Numerical results indicate that the complex variable finite element method has good performance for solving elastoplastic problems of three-dimensional geometries. The inversion method is effective and accurate for simultaneously identifying multi-parameters of power hardening elastoplastic problems in three-dimensional geometries, which could be employed for solving inverse elastoplastic problems in engineering applications.
Originality/value
The constitutive parameters and boundary conditions are simultaneously identified for power hardening elastoplastic problems in three-dimensional geometries, which is much challenging in practical applications. The numerical results show that the inversion method has high accuracy, good stability, and fast convergence speed.

Abstract
Purpose
The purpose of this paper is to develop a combined method for three-dimensional incompressible flow and heat transfer by the spectral collocation method (SCM) and the artificial compressibility method (ACM), and further to study the performance of the combined method SCM-ACM for three-dimensional incompressible flow and heat transfer.
Design/methodology/approach
The partial differentials in space are discretized by the SCM with Chebyshev polynomial and Chebyshev–Gauss–Lobbatto collocation points. The unsteady artificial compressibility equations are solved to obtain the steady results by the ACM. Three-dimensional exact solutions with trigonometric function form and exponential function form are constructed to test the accuracy of the combined method.
Findings
The SCM-ACM is developed successfully for three-dimensional incompressible flow and heat transfer with high accuracy that the minimum value of variance can reach. The accuracy increases exponentially along with time marching steps. The accuracy is also improved exponentially with the increasing of nodes before stable accuracy is achieved, while it keeps stably with the increasing of the time step. The central processing unit time increases exponentially with the increasing of nodes and decreasing of the time step.
Research limitations/implications
It is difficult for the implementation of the implicit scheme by the developed SCM-ACM. The SCM-ACM can be used for solving unsteady impressible fluid flow and heat transfer.
Practical implications
The SCM-ACM is applied for two classic cases of lid-driven cavity flow and natural convection in cubic cavities. The present results show good agreement with the published results with much fewer nodes.
Originality/value
The combined method SCM-ACM is developed, firstly, for solving three-dimensional incompressible fluid flow and heat transfer by the SCM and ACM. The performance of SCM-ACM is investigated. This combined method provides a new choice for solving three-dimensional fluid flow and heat transfer with high accuracy.

Abstract
Purpose
The purpose of this paper is to look at the insights of the value of the society influenced by sharing economy (SE). The study focused on both the benefits and flaws of SE by using the case of renowned SE platform “Uber” to come up with a holistic perspective of these effects from both the facets.
Design/methodology/approach
This study collects data from demand and supply side using interview and questionnaire. Then the grounded theory is adopted to analyze interview data and come up with six major research constructs. Further, quantitative analyses methods are applied on questionnaires to test “whether sharing economy creates social value” and to approximately estimate the extent to which sharing is economy influencing social value.
Findings
Findings suggested that, when only drivers were inquired about positive and negative effects of SE, positive effects were dominant. Also, when passengers were asked their opinion was also in favor of positive effects. From quantitative data analysis, the major factor significantly influencing the sustainability of the SE was “efficiency.” “Security issues and regulatory issues” were the prime negative factors, though again there was not enough statistical evidence to validate their significance. The authors hereby conclude that the positive contribution of SE is more, and it is increasing the values of the society. And the positive effects were twice significant than the negative effects.
Originality/value
Theoretically, the study contributes to finding both the helpful and harmful effects of SE on the values of the society. Practically, it suggests that governments should allow growth of SE under proper regulations. And car-sharing companies should focus on solving the security issues and regulatory issues.

Abstract
Purpose
An increasing number of Chinese enterprises are involved in cross-border mergers and acquisitions (M&As). However, few Chinese enterprises have achieved successful integration, which plays a critical role in enhancing performance. The important field of cultural integration is currently facing major challenges. To identify the reasons for these challenges, studies have analyzed why cultural integration succeeds or fails and have suggested that cultural differences between acquiring and acquired enterprises are the primary obstacles to cultural integration. However, it is unclear how success can be achieved. The paper aims to focus on cultural integration from the perspective of acculturation to describe the penetration of cultural elements in M&As.
Design/methodology/approach
In adopting acculturation as our theoretical lens, the authors use the case study method to answer the following research question: “how can the cultural integration of Chinese enterprises be successfully achieved?” Two typical cases are examined: Lenovo’s cultural integration with IBM’s personal computer (PC) division and Haier’s cultural integration with Sanyo home appliance. First, using the exploratory case study method, the Lenovo–IBM PC division case is analyzed. The characteristics and relationships between cultural environments, employee adoption methods and acculturation patterns are summarized to reveal a cultural integration path. Second, the Haier–Sanyo home appliance case is analyzed using the confirmative case study method to test the findings of the Lenovo–IBM PC division case.
Findings
The results indicate that it is critical to achieve a dynamic fit between cultural environments, employee adoption methods and acculturation patterns during each stage of cultural integration (exploration, experimentation, reinforcement and fixing). The three constructs of these stages reflect the following evolutionary paths: “isolate-introduce-learning-chance taking”, “detecting-icebreaking-interacting-remodeling” and “specialized sections-senior managers-managers-employees”.
Originality/value
These findings contribute to the development of cultural integration and acculturation theories and serve as a reference for Chinese enterprises wishing to implement cultural integration strategies.

Abstract
Purpose
The purpose of this paper is to propose a new strong-form numerical method, called the free element method, for solving general boundary value problems governed by partial differential equations. The main idea of the method is to use a locally formed element for each point to set up the system of equations. The proposed method is used to solve the fluid mechanics problems.
Design/methodology/approach
The proposed free element method adopts the isoparametric elements as used in the finite element method (FEM) to represent the variation of coordinates and physical variables and collocates equations node-by-node based on the newly derived element differential formulations by the authors. The distinct feature of the method is that only one independently formed individual element is used at each point. The final system of equations is directly formed by collocating the governing equations at internal points and the boundary conditions at boundary points. The method can effectively capture phenomena of sharply jumped variables and discontinuities (e.g. the shock waves).
Findings
a) A new numerical method called the FEM is proposed; b) the proposed method is used to solve the compressible fluid mechanics problems for the first time, in which the shock wave can be naturally captured; and c) the method can directly set up the system of equations from the governing equations.
Originality/value
This paper presents a completely new numerical method for solving compressible fluid mechanics problems, which has not been submitted anywhere else for publication.

Abstract
Purpose
Chatbots have been explored as a novel approach to enhancing consumer engagement by delivering more enjoyable, personalized services. This research aims to investigate the mechanism through which anthropomorphic elements of chatbots influence consumers' intentions to use the technology.
Design/methodology/approach
This research introduces five key concepts framed through the “computers-are-social-actors” (CASA) paradigm: form realism (FR), behavioral realism (BR), cognitive trust (CT), entertainment (EM) and chatbot usage intention (CUI). An online questionnaire garnered 280 responses from China and 207 responses from Indonesia. Data collection employed a combination of purposive and snowball sampling techniques. This research utilized structural equation modeling through the analysis of moment structures (AMOS) 27 software to test the hypotheses.
Findings
(1) FR positively predicts CT and EM, (2) FR negatively predicts CUI, (3) BR positively predicts CT and EM, (4) BR positively predicts CUI and (5) Both CT and EM mediate the relationship between FR and CUI, as well as between BR and CUI.
Originality/value
This research enriches the current literature on interactive marketing by exploring how the anthropomorphic features of chatbots enhance consumers' intentions to use such technology. It pioneers the exploration of CT and EM as mediating factors in the relationship between chatbot anthropomorphism and consumer behavioral intention. Moreover, this research makes a methodological contribution by developing and validating new measurement scales for measuring chatbot anthropomorphic elements.

Abstract
Purpose
The purpose of this paper is to obtain the optimal N2/Ar ratio parameters for preparing Ta (C, N) coating. Three coatings with different N2/Ar ratios were prepared on the TA15 substrate, and their effects on the wear properties of the coatings were discussed.
Design/methodology/approach
Ta(C, N) coatings with three different N2/Ar ratios were prepared on TA15 substrates using the double cathode glow metallurgical plasma alloying technique (DGMPA) using a step-by-step diffusion method.
Findings
With the increase of N2/Ar flow ratio, the hardness and elastic modulus of the coating first increase and then decrease. Compared with the S1 sample (N2/Ar gas ratio 25: 75) and the S3 sample (N2/Ar gas ratio 75: 25), the S2 sample (N2/Ar gas ratio 50: 50) has better mechanical properties, with hardness increased by 48.45% and 6.8%, respectively, and elastic strain ratio increased by 22.8% and 28.5%, respectively. Moreover, the wear degree of the S2 sample is less than other samples. The wear rate of the S2 sample was 32.4% lower than the S3 sample at 300°C and 14.3% lower than the S3 sample at 500°C. Therefore, the S2 sample has the best mechanical properties and the best high temperature wear resistance.
Originality/value
Ta(C, N) coatings were prepared by DGMPA technology, and the wear mechanism of Ta(C, N) coatings with different N2/Ar ratios was investigated to reduce the wear rate.

Abstract
Purpose
The purpose of this paper is to analyze the historical pattern of environmental cost due to grain production in China and to provide further implications of technologies and policies for the transformation of China’s agricultural development toward sustainable intensification.
Design/methodology/approach
The data sets about grain production, arable land and chemical fertilizer use in China were collected from FAO, NBSC, and IFA. Greenhouse gas emissions were estimated using life cycle assessments. The policies concerning grain production and the environment were collected from the Ministry of Agriculture, and the State Council of China.
Findings
China has produced enough food to feed its growing population, but has neglected the resource-environmental costs of grain production since 1978. Consequently, China’s grain production is always accompanied with a high cost of resource and environment sustainability. However, from 2006 to 2015, the growth rate of grain production has surpassed that of chemical fertilizer consumption, resulting in improvement in nutrient use efficiency and decreasing trends of environmental cost for grain production. This could be partially attributed to technology innovations, such as Soil-Testing and Fertilizer-Recommendations (STFR), soil quality and crop management improvement, and so on, and policy supports (policies of STFR, soil quality improvement, and high-yield construction). This indicated that China’s grain production is starting to transform from high-input and high-output model to “less for more.”
Originality/value
This study is the first to determine the detailed, historical role of technological innovation and agri-environmental policy on the sustainability of grain production in China. The findings should have significant implications for technology and policy for the transformation of China’s agriculture development to sustainable intensification.
