The motivation for analyzing the impact of deep neural networks on enterprise performance is mainly due to the continuous deepening of enterprise information construction, shifting from traditional paper-based data acquisition methods to electronic data management. The data generated by the sales, production, logistics and other links of enterprises is also becoming increasingly large. How to scientifically and effectively process these massive amounts of data and extract valuable information has become an important issue that enterprises need to solve. The continuous and stable growth of China's economy has promoted the development and growth of enterprises, however, it has also made enterprises face a more complex competitive environment. The question of how to improve the performance of enterprises to enhance their competitiveness in the market has become a major issue to be addressed in the face of fierce competition and to ensure the long-term development of enterprises. In this paper, based on the research of firm performance evaluation, deep neural network is introduced to analyse the influence of ambidextrous innovation and social network on firm performance, and the theories of social network, ambidextrous innovation and deep neural network are sorted out and analysed, and a deep neural network-based firm performance evaluation model is established, and finally the sample data is obtained using crawler technology, and then the response values are analysed. Innovation and the improvement of the mean value of social networks are helpful to firm performance.

This study focuses on the evolution of growth model and cultivation of competitive advantages under the ambidextrous innovation strategy. After a brief introduction of the connotation of ambidextrous innovation strategy, the evolution of growth model of high-tech enterprises under the conventional strategy and the ambidextrous innovation strategy is analyzed. Furthermore, a discussion is made on how to cultivate enterprises’ competitive advantages under the ambidextrous innovation strategy, thereby enabling enterprises to stand out from competitors under this new strategic model and truly achieve the goal of sustainable development.
