This study aims to explore key factors and specific ways for the upgrade to hybrid incubators in the context of China. A hybrid incubator means that a technology-based business incubators (TBIs) can implement various distinct value creation processes with the integration of the advantages of non-for-profit and for-profit TBIs at same time as Chinese government now requires government-sponsored non-for-profit TBIs to be profitable self-sustainability with less dependent on direct public subsidies, aiming to motivate these TBIs to provide higher quality services for their tenant new technology-based firms (NTBFs).

This study conducts a single in-depth case-study of Tuspark Incubator (located in Tsinghua Science Park [TSP]) with categorical analysis.

Three factors, i.e. incubation subdivision, intermediary platform and proactive approach, are found to be essential for a formerly government-sponsored TBI’s upgrading. Incubation subdivision enables Tuspark Incubator to create multiple incubation processes with incubator characteristic variables of both non-for-profit and for-profit incubators; with the establishment of intermediary platform, Tuspark Incubator provides specialized business support and high-quality networking from relevant specialized service organizations external to the incubator; more proactive approach with equity investment on incubating firms from Tuspark Incubator help to generate social welfare and financial profit at the same time.

For the incubators’ managers, incubation subdivision enables TBIs to operate for-profit and non-for-profit processes at the same time and provides different specific needs; more open intermediary service platforms can leverage the full potential of the actors in innovation system and help TBIs to save resource when upgrading to hybrid incubators; proactive approaches nurture learning climate and entrepreneurship environment to enhance the successful rate on NTBFs inside incubators and provide main profit source for incubators. For policy makers, using proactive approaches including creating a good milieu for incubation on technology-based start-ups and the design of public guidance funds is increasingly crucial.

This research is a pioneering study on the key factors and specific ways for the upgrade of government-sponsored non-for-profit TBIs in China to hybrid for-profit and non-for-profit incubators.

Studies have documented the distinctive advantage of innovation ecosystems in integrating and recombining heterogeneous knowledge resources across firms' boundaries. However, hierarchical governance in the form of vertical integration is still preferred in many industries for organizing innovation, and the current literature touches little on the relative performance of different organizational structures (integrated firms vs innovation ecosystem) and the factors that lead firms to choose one over the other. The authors conjecture that structure of technological interdependence is one of such important factors. Using a computational experiment, the authors compare the innovation performance of ecosystems with integrated firms under different interdependency structures.

Using the NKC model, the authors incorporate non-generic complementarities and modularity into the technological interdependence between different components. The authors compare four different types of technological interdependence (modular, hierarchical, nearly modular, and random).

The results show that integrated firms with centralized search demonstrate stable and consistent performance that is robust to the structure of technological interdependencies, but an ecosystem significantly outperforms integrated firms with centralized or decentralized when the products exhibit modular or nearly-modular structures.

This study sheds light on why an ecosystem often exhibits modular structures while vertical integration is prevalent in industries with complex technological interdependence. In addition, it shows the evolutionary nature of ecosystems and indicates how the cooperation and competition between actors shape the interdependence structure of ecosystems.

This study aims to test the effects of Technology-related Divestitures (TRDs) on firms' exploratory innovation. The moderating effects of firms' internal and external resource coordination activities, resource buffering and bridging, are also explored.

A set of data including 1,372 Chinese listed firms from 2009 to 2018 is adopted. Based on propensity score matching sample, random-effect Tobit models were employed to test the hypotheses.

The empirical results indicate that TRDs inhibit firms' exploratory innovation, while both resource buffering and bridging can mitigate this negative effect. This implies that to promote exploratory innovation, resource coordination activities are the essential.

The research findings can contribute to both the exploratory innovation and technological divestiture literature. The test on the moderating roles of resource buffering and bridging can also extend our understanding of the effect of TRDs on firms' exploratory innovation. Accordingly, several practical implications can be provided. This is especially important for strategic decisions of firms from emerging and developing countries, which often lack sufficient internal resources and strong technological capabilities to develop exploratory innovation.

The purpose of this paper is to elaborate on the interactive conflicts between business and governmental authorities in the regulatory process of an emerging business model: sharing economy. Focusing on bike sharing system, the study also investigates the conflict-handling strategy of bike sharing companies and government regulation.

An evolutionary game model is introduced to illustrate the interactive conflict between bike sharing companies and government regulation, combined with system dynamics (SD) to simulate the evolutionary conflict-handling strategies between the two players.

The dynamic strategies of the two players are observed, and under five conditions the conflict outcomes are evolutionary stable states. Simulations show that each party sacrifices part of its interest and adjust its strategy according to that of the other, indicating the conflict-handling strategy as a compromising mode. Furthermore, the strategies of bike sharing companies are sensitive to additional operation and maintenance costs for producing low-quality bicycles and costs of positive regulation, which provides theoretical guidance for regulatory authorities.

The station-less bike sharing come up in China recently, and it is an important research field of entrepreneurship. Owing to the uniqueness and novelty of the phenomenon, conflicts and challenges exist during the regulation process. Thus, the study practically contributes to the conflict-handling strategies of businesses and government under the context of sharing economy. Methodologically, as a novel issue with less available data to carry out empirical research, this study combines evolutionary game theory with SD to shed light on the complex interactions between businesses and government. The research method can be applied to other entrepreneurial studies.

The purpose of this paper is to explore and highlight the particular innovation characteristics and modes of the Chinese online game industry from a networking perspective.

This research is qualitative. Both primary and secondary data are used, which is collected through desk research on related documents and long‐term participative observation and personal experiences. This paper begins with an overview of the online game industry's innovation process and types; then constructs a framework that contains four innovation modes with different networks to guide the analysis and organization on the empirical findings; finally, the paper proposes some implications for companies and government.

This paper is an attempt to open the black box of the innovation of the Chinese online game industry. Born as an incomplete and virtual product, the innovation modes evolve from closed to a combination of open and networking ones. Producer‐driven Innovation Network Mode shows that game companies can get innovation resources through its focal network. Producer‐user Interaction Mode shows that players' have tremendous innovation potential. Open Collaborative Network Mode shows that power is distributed and the roles of actors are blurred.

This paper offers an analysis of the Chinese online game industry from the innovation side and partly fills the research gap. Also, this paper emphasized the users' innovation ability and a hybrid of different innovation modes, which can be seen as a successful theory test of user innovation, innovation networks, and open innovation theories in the Chinese context.

The purpose of this paper is to conceptualize and make sense of the internationalization of the triple helix (TH) model.

As this study is exploitative in nature, an inductive approach is adopted in data collection and data analysis. The Danish TH's experiences in China are used as empirical evidences. Primary data are collected from in-depth interviews and discussions, filed observations, and personal experiences. Secondary data such as the government policies and documents, companies’ annual reports, and reliable web sites are also included.

The paper conceptualizes the internationalization of the TH into three stages: pioneering stage, exploration stage, and integration stage. In the pioneering stage, the authors see the establishment of each of the three helix spheres abroad, i.e. internationalization of companies, universities and governments; in the exploration stage, the three spheres start to interact abroad and collaborate with their counterparts in the host country; in the integration stage, helix to helix collaboration is emerging.

This study has both theoretical and practical significance. It expands the existing TH theory by proposing a model for the internationalization of it. On the other hand, this study gives implications regarding utilizing global knowledge resources and enhancing innovation performances overseas.

The formation of unmanned aerial vehicle (UAV) swarm plays a critical role in numerous applications, such as unmanned agriculture, environmental monitoring and cooperative fencing. Meanwhile, the self-organized swarm model exhibits excellent performance in amorphous formation flight, and its collective motion pattern displays great potential in dense obstacle avoidance. The paper aims to realize the formation maintenance of UAVs while combining the advantage of the self-organized swarm model in avoiding dense obstacles. Thereby enhancing the flexibility, adaptability and safety of UAV swarms in dense and unpredictable scenarios.

In this paper, a self-organized formation (SOF) swarm model with a constrained coordination mechanism is proposed. A global information-based formation rule is designed to flexibly maintain the formation. A constraint coordination mechanism is designed to resolve the problem of constraint conflicts between formation rules and self-organized behavior rules. The model introduces a new obstacle avoidance rule to prevent deadlocks. Extensive experiments including simulations, real flights and comparative experiments are conducted to evaluate the performance of the model.

The simulation results show that SOF swarm enables the formation elastically to dense obstacles. Compared to the Vasarhelyi model, swarm performance metrics are improved. For example, the task completion time of SOF swarm is reduced by 16%, 28% and 39% across the three obstacle densities, and the order of SOF swarm is improved by 4%, 13% and 18%, respectively. The proposed model is also validated with a swarm of seven quadcopters that can successfully navigate and maintain formation in a real-world indoor environment with dense obstacles.

The proposed formation rule is based on global information construction, which presents challenges in terms of communication overhead in distributed systems.

An SOF swarm model is proposed, which achieves formation maintenance by incorporating formation rule and constraint coordination mechanism and improves obstacle avoidance performance by introducing a new obstacle avoidance rule. After real UAVs verification, the model is feasible for practical deployment and provides a new solution to the formation flight and formation maintenance problems encountered in dense environments.

The purpose of this paper is to present a visual servo tracking strategy for the wheeled mobile robot, where the unknown feature depth information can be identified simultaneously in the visual servoing process.

By using reference, desired and current images, system errors are constructed by measurable signals that are obtained by decomposing Euclidean homographies. Subsequently, by taking the advantage of the concurrent learning framework, both historical and current system data are used to construct an adaptive updating mechanism for recovering the unknown feature depth. Then, the kinematic controller is designed for the mobile robot to achieve the visual servo trajectory tracking task. Lyapunov techniques and LaSalle’s invariance principle are used to prove that system errors and the depth estimation error converge to zero synchronously.

The concurrent learning-based visual servo tracking and identification technology is found to be reliable, accurate and efficient with both simulation and comparative experimental results. Both trajectory tracking and depth estimation errors converge to zero successfully.

On the basis of the concurrent learning framework, an adaptive control strategy is developed for the mobile robot to successfully identify the unknown scene depth while accomplishing the visual servo trajectory tracking task.

The purpose of this study is to propose a path-planning strategy based on the velocity-virtual spring method to realize collision-free tasks in dynamic environments and further improve the effect.

By considering factors such as the relative velocity and direction of dynamic obstacles, the repulsive force of the robot is improved, thereby enhancing the adaptability of the strategy and achieving flexible and effective avoidance against dynamic obstacles. The attraction formula has been designed to allow the robot to have better smooth changes and higher gradients near the target, helping robots better reach the target and follow formations. Moreover, to meet the demands of the various stages during the driving process, the null space behavioral control is used to solve multi-task conflict problems and strengthen formation coordination and control.

Comparison of the planning path and formation effects through simulation and physical experiments, the results of this study show that the algorithm proposed can successfully maintain formation stability and plan smooth and safe paths in static or dynamic environments.

This paper proposes a path-planning strategy based on the velocity-virtual spring method to plan collision-free paths for formation in dynamic environments.
