With the development of the digital economy, digital entrepreneurship has become increasingly popular. For college students preparing for digital entrepreneurship, it is necessary to cope with the uncertainty of the start-up process through meaningful managing learning and continuous entrepreneurship education. The purpose of this study is to examine the relationship between Chinese college students' digital entrepreneurship intention and digital entrepreneurship behavior, as well as the role of managing learning and entrepreneurship education in this relationship.

Based on the existing literature, this study established the digital entrepreneurship hypothesis model and investigated the digital entrepreneurship behavior of college students.

The results showed that managing learning and entrepreneurship education can promote the transformation of the digital entrepreneurship intention to digital entrepreneurship behavior. Managing learning and entrepreneurship education played a driving role in the transformation of the digital entrepreneurship intention to digital entrepreneurship behavior.

This study explored the complex mechanism of the relationship between digital entrepreneurship intention and digital entrepreneurship behavior among Chinese college students. Based on survey data from 235 college students in China, the empirical results supported theoretical research hypotheses on the relationship between college students and digital entrepreneurship intention, digital entrepreneurship behavior, managing learning and entrepreneurship education.

Entrepreneurial competence plays a decisive role in entrepreneurship success. To promote the employment of college students and accelerate economic growth through entrepreneurial activities, the Chinese government and universities encourage the use of multiple inputs to boost holistic entrepreneurship education and training. This study aims to assesses the entrepreneurial competence of college students by analysing the effects of entrepreneurship education and policy implementation in China.

The quantitative approach considered a large sample of 12,269 students, who participated in entrepreneurship education in Chinese “double-first-class” universities, to construct a theoretical model of their entrepreneurial competence. Entrepreneurship competition was introduced as a mediating variable in this model.

This study revealed that college students develop entrepreneurial competence by participating in entrepreneurship competitions unlike students who participate in regular entrepreneurship education. Additionally, there was a significant difference in the measured impact of entrepreneurship policy between students who participated in entrepreneurship competitions and those who did not.

The effects of the implementation of entrepreneurship education and policy were studied using a quantitative design. Additionally, this study highlights the effect of entrepreneurship competitions with empirical evidence from China, and contributes to the discussion of entrepreneurship education at schools and entrepreneurship policy for policymakers.

The paper attempts to analyze the network structure of value activity in manufacturing clusters, propose the model of value creation of cluster's value activity network, and explore the inner mechanism and optimization strategies of value creation in manufacturing clusters from the perspective of cluster's value activity network.

This paper applies a genetic algorithm to optimally search in the target space, and repeatedly exerts genetic operation (select, cross, variation) on the population to explore the optimal configuration strategy between value creation activity and resource utilization. It also analyzes the relation between object function of value creation and relative parameters.

The total value created by value activity network was impacted by the degree of effective configuration between all kinds of resources and value activities; the total value created by value activity network is positively related to activity units' elasticity coefficient of value creation of human resource, material resources and relations resource, and is negatively correlated to cost coefficient of human resource, material resources and relations resource; when the cooperative relations between activity units create positive relationship profit, the total value created by value activity network increases with the increase of cooperative relations between activity units.

Enterprises in clusters should reasonably configure and incorporate the resource among value activities through adding, deleting or reconfiguring activities, which makes the value activities network create maximum value; enterprises can transform the type of activity units to increase elasticity coefficient of value creation of human resources, such as transforming production activities into the high value‐added activities; enterprises can optimally incorporate the technical, material resources and human resources among activities to increase value creation elastic coefficient of material resources; enterprises can decrease cost coefficient by maintaining the stability of long‐term cooperation with the suppliers and strengthening the cultivation of talents; enterprises can increase profits from relation resource or reduce cost coefficient of relationship by updating activities, building trust mechanism and communication mechanisms and establishing long‐term cooperation relationship to improve value creation activities.

This paper proposes the model of value creation from the perspective of cluster's value activity network, and applies a genetic algorithm to explore the optimal configuration strategies between value creation activity and resource utilization.

This study aims to investigate the efficacy of micro dimple in inhibiting stick-slip phenomenon on the sliding guideway.

In this study, micro-dimples were fabricated by laser on surfaces of steel disk and guideway. The disks and guideways were respectively performed pin-on-disk tribological tests and working condition experiments to study differences in lubrication condition and friction stability between textured and untextured surfaces.

Micro-dimples help reduce critical sliding speed that allows contact surfaces to enter in hydrodynamic lubrication regime. This increases hydrodynamic lubrication range and narrows speed range where stick-slip phenomenon can occur, enhancing sliding guideway’s adaptability for broader working conditions. Furthermore, friction stability on the textured surface improved, lowering the occurrence possibility of stick-slip phenomenon. Finally, difference between static and kinetic frictions on the textured surface is lower relative to the untextured surface, which decreases the critical velocity when the stick-slip phenomenon occurs.

The results indicate that laser-textured micro-dimples are significantly conducive to inhibit stick-slip phenomenon, thus providing smoother movement for the guideway and eventually increasing precision of the machine.

Considering the limitation of the single stage vendor selection model, this paper proposes a two‐stage vendor selection framework for IT outsourcing in microfinance banks.

The paper attempts to realize a complete analysis at company level using grey systems theory for shaping the relations among variables. With the social choice function – Dodgson function, the first stage is a trial phase that helps the decision‐maker find the potential vendors, then, the decision‐maker employs those chosen vendors for the final selection with modified grey relational analysis (GRA) integrated analytic network process (ANP), which emphasizes the interrelation among those selection criteria, and avoids the subjective estimation of experts and practitioners. The case of a microfinance bank IT outsourcing vendor selection is used to verify the proposed approach.

The results of the empirical study show that the proposed method is practical for ranking competing vendors in terms of their overall performance with respect to multiple interdependence criteria for the bank's IT outsourcing.

The method exposed in the paper can be used for other supplier selection by modifying some criteria and weight.

The paper provides a method for ranking competing vendors in terms of their overall performance with respect to multiple interdependence criteria for IT outsourcing.

This paper attempts to study the impact of changing incentive strategies on enterprises' energy saving effort level and to construct an effective principal‐agent mechanism to achieve Pareto improvement of energy‐saving control.

Starting from the benefit relations between government and enterprises as well as their game strategies in energy conservation management, the impact of changing incentive strategies on enterprises' energy saving effort level and the asymmetric information situation of the players are studied taking into consideration the angle of strategies evolving in local government. Also, an effective principal‐agent mechanism to achieve Pareto improvement of energy‐saving control is constructed.

The results are convincing: interests of both the principal and agent had consistency under the principal‐agent mechanism, and the principal‐agent model was a mechanism with rich efficiency that could substantially arouse the enthusiasm of enterprises in energy saving. The comprehensive supervision of local governments over enterprises could effectually eliminate ill effects on energy‐saving management caused by information asymmetry under certain circumstances.

It is good for locating the balance of interest of game players by building a government energy saving mechanism based on principal‐agent theory. Through solving a game stable strategy, it is beneficial to seize a key point of regulation and control policies.

The paper succeeds in analyzing decision behaviours of government and enterprises through the basic idea of cooperative game theory so as to make actions of enterprises at all levels agree to government determined solving of energy issues.

The purpose of this paper is to show which models, uncertain or certain, simple or complicated, are more suitable when they are faced with incomplete information and inaccurate data.

The characteristics of fuzzy mathematics, grey system theory, rough set theory and the basic characteristics of incomplete information and inaccurate data in uncertain systems are analysed.

The similarities and differences among fuzzy mathematics, grey system theory, rough set theory and probability statistics are compared. The principle of simplicity of scientific theories, methods, and models are discussed.

It is suggested that the tendency to concentrate on a complicated model isn't always necessary when faced with the condition of incomplete information and inaccurate data.

The paper shows that a more satisfied result can be obtained with an uncertain model than with a meticulous model on a certain situation.
