## 5 Discussion  
This paper takes China's computer information service industry as an example for study. Firstly, the international competitiveness of China's computer information service industry is evaluated by the RCA index. It is found that the international competitiveness is rising year by year, and the industry is developing in a good state. However, compared with Ireland and India, there is still a large gap. Secondly, the industry international competitiveness indicator system of influencing factors is conducted from high-quality development, and the grey correlation degree analysis is carried out. Ten indicators such as GDP per capita, the export value of goods, R&D investment intensity, and the export value of other services are significantly correlated to competitiveness. Finally, combining the Grey theory and BP neural network algorithm, a GM-BP neural network model for predicting the international competitiveness of the computer information service industry is established. Through forecasting, it is found that the future growth trend of the international competitiveness of China's computer information service industry will slow down. Through the analysis of the predictive results, the GM-BP prediction model has higher accuracy than the GM (1,1) model prediction, which verifies the rationality of the prediction model established in this paper. Through the analysis of the results, this paper further points out the direction of and recommendations for the improvement of the international competitiveness of China's computer information service industry:  
1. **Deepen international cooperation and enhance the comprehensive strength of the industry. ** First, deepen cooperation with Ireland, India, and other countries with the help of government, international organizations, and industry associations, by introducing their advanced technology and operational management experience, accelerating the accumulation and optimization of the industry's high-end elements, and enhancing the level of the industry in the global value chain [39]. Second, seize the opportunities of global economic servitization and the fourth industrial revolution, continuously improve service quality and level following international standards, deepen relations with existing partners, and stabilize and expand the international market. At the same time, continue to expand the export of various goods and

Third, encourage powerful companies in the computer information service industry to go global, seize the opportunity of China's implementation of free trade agreements with many countries, establish cooperation channels with emerging markets, and diversify export risks. 2. **Strengthen investment in innovation and stimulate internal driving forces of the industry. ** First, organize industry experts to focus on key technical areas, analyze technology development trends and international competitors, and guide enterprises to implement patent reserves and layout in a planned and targeted manner. At the same time, promote the integration, breakthrough, and industrialization of patented technologies, promote the upgrading of the industrial value chain and maximize the value of corporate patents. Second, use industry organizations to build patent alliances, guide enterprises to strengthen patent applications, encourage patent concentration and cross-licensing, strengthen technical barriers through patent pools, and enhance the overall competitive advantage of the industry.
