The objectives of this thesis are to analyse the marketing barriers for aeroengine business in China and to develop a new model that integrates all relevant elements together. At the same time the thesis should provide systematic guidance to aeroengine manufacturers regarding marketing barriers in China. During the research, the following hypothesis has emerged: China has specific marketing barrier factors that have predominantly influenced the Chinese purchase decision-making processes regarding aeroengine business with foreign companies. These factors can be identified from a study of aeroengine business activities in China with particular reference to the business history of Rolls-Royce pIc, General Electric, Pratt & Whitney and Russian manufacturers in China in the 20th and 2151 centuries. . On the basis of the hypothesis, the theoretical modelling is developed in Chapter 4 'Theoretical Modelling'. The marketing barriers are identified and a new model 'International marketing strategy: marketing barriers for aeroengine business in China' is developed. Chapter 5 'Application Of Model' applies the new model to some selected Primes' and Russian business cases in China, evaluates the weightings of barriers and their influence on the chosen business cases through a matrix approach, and identifies the most important barriers. Chapter 7 'Recommendations' recommends how to apply the new model and some possible solutions to overcome the most important barriers. In addition, further research work is also discussed. In conclusion, this thesis contributes significantly to current academic theory and industrial practice in the following ways: By filling in the research gap in the specific topic 'marketing barriers for aeroengine business in China'; By formulating a systematic approach (i.e. the new model) to review the marketing barriers instead of the conventional approach that focuses only on the government-imposed measures and policies.
