National security is a very important task of party governance, and economic security is an important part of national security. Since its establishment, the Communist Party of China (Hereinafter referred to as CPC) has attached great importance to economic security work, and has always firmly grasped economic security work in its own hands. In the course of a hundred years of struggle, the CPC’s economic security ideology has gradually formed. The CPC’s thought on economic security has gone through the infancy, embryonic period, growth period and maturity period. By sorting out the historical evolution of the CPC’s thought on economic security and summarizing the historical experience of the CPC’s uniting and leading the people to achieve major achievements in economic security over the past hundred years, it is conducive to deepening our regular understanding of economic work under severe challenges, and based on safer and more reliable high-quality development in the new era.
