There are different views on how to gain a sustainable competitive advantage (SCA) for firms. This topic has become an important research area in strategic management. The purpose of this paper is to provide an approach for Chinese firms to use as a springboard to identify sources of SCA through marketing innovation.

Based on a cursory review of the generic literature on how to gain SCA, this paper considers innovation as a primary source of a firm's competitive advantage. From a practical viewpoint, marketing innovation is identified as a significant source of SCA, especially for those firms operating in the dynamic and competitive Chinese economic environment. Through an analysis of marketing innovations at the Huawei Technologies Co. Ltd in China, an approach is developed to help managers identify their unique sources of SCA through marketing innovation.

This study reveals marketing innovation results from a considered analysis of the various marketing factors in the environment and the inter‐relationships between these factors. Subsequently, new sources of SCA can be identified, based on a firm's previous sources of competitive advantage. In this process, different types of competitive advantage are viewed in a holistic framework, which provides the basis for improving firm performance.

The approach developed in this paper offers a basis for managers to identify their firm's unique SCA through marketing innovation.

The paper provides insights for academics and professionals in the field and adds to the literature on emerging economies and SCA.

The present study aims to resolve the adjustment problem of cavitation bubble number density in simulations of the cavitating flows within the diesel injection nozzle holes using a two-fluid cavitation model.

The basic rule that determines the variations of cavitation bubble number density has been checked through the scaling analysis of a two-fluid model under the assumption of hydrodynamic similarity of the cavitating flows. Moreover, a phenomenological model for the number density of cavitation bubbles that takes the hydrodynamic effect into account has been developed through the combined analysis of cavitation bubble dynamics and internal flow characteristics of diesel injection nozzle holes. This new model has also been validated by the discharge coefficient measures in a wide range of injection conditions.

The values of cavitation bubble number density must rationally match changes both in liquid quality effect and in hydrodynamic effect corresponding to different cavitating flows. The validation results show that the two-fluid cavitation model together with this new cavitation bubble number density model predicts well both the cavitation content inside the diesel nozzle hole and the relationship between discharge coefficient and cavitation number, and the new cavitation bubble number density model has the potential to further expand the application range of the two-fluid cavitation model.

This study provides insight into hydrodynamic effect corresponding to cavitating flows inside diesel nozzle holes and presents an idea to model the cavitation bubble number density phenomenologically. The model idea and the developed model are useful to researchers and engineers in the area of nozzle internal flow and cavitating flow.

Adaptive reuse of building assets is an important approach to sustainability. Adapting a building for new uses often involves complex factors in the decision-making process, particularly in conservation areas. The paper aims to show an evaluation process of the adaptive reuse potential of historic buildings that are subject to change in the Grand Canal area, a world heritage site in Hangzhou, China.

For this purpose, a model has been established with aggregated views of professionals on the degree to which a variety of factors affect the buildings’ potential for adaptive reuse. The model intends to help prioritise some of the buildings in the area for adaptive reuse, which is important for effective allocation of public resources. Interviews with professionals, analytic hierarchy process and the Delphi method have been used to establish the evaluation model. It is then applied to the Grand Canal area to generate indices for buildings’ adaptive reuse potential and the ranking of priority. The indices are generated through public scoring of historic buildings against the variables and calculated through the model.

The paper concludes that the evaluation process is an effective way to engage the public in the decision-making process and to balance conflict interests of various stakeholders in the management of historic building assets in conservation areas.

The research has proposed an evaluation model to help set priority of buildings subject to adaptive reuse and to help distribute public fund effectively. It facilitates wide public engagement in the decision-making progress of adaptive reuse of historic buildings.
