新经济政策时期，列宁提出了对外开放的思想，并付诸了苏维埃俄国恢复和发展国民经济的实践。邓小平在领导和指导建设有中国特色社会主义的伟大实践中，系统地提出了对外开放的理论，并在实践中取得了巨大成就。邓小平对外开放理论直接来源于列宁思想，而且更具系统性、完整性和实践性，是对列宁思想的丰富和发展。 During the new economic policy, Lenin put forward the idea of ​​opening to the outside world and put into practice the Soviet Union’s recovery and development of the national economy. In his great practice of leading and guiding the construction of socialism with Chinese characteristics, Deng Xiaoping systematically put forward the theory of opening to the outside world and made tremendous achievements in practice. The theory of Deng Xiaoping’s opening to the outside world derives directly from Lenin’s thought. It is more systematic, complete and practical. It is an enrichment and development of Lenin’s thought.
