China urgently needs to pay attention to the cultivation of new economic kinetic energy in the western region so as to achieve a stable shift in economic growth and promote the economy towards high-quality development. As an endogenous dynamic factor of economic growth, new kinetic energy fully emphasizes the recycling and utilization of production factors, the high efficiency of production behavior, and the optimization and upgrading of industrial structure. As the core breakthrough point for the comprehensive realization of China's modernization in the new era and the main conquering area for China's coordinated and balanced development, the completion of the new economic dynamism in the western region has become an arduous and necessary task in the process of high-quality development. Based on the background of the new era of economy, by constructing the theoretical framework and indicator system of new kinetic energy cultivation, we measure and evaluate the current development status of new kinetic energy cultivation in western China in order to propose policy recommendations and adaptive path selection for the development of new economic dynamism in the western region of China.
