摘　　要：我国正处于经济由高速发展转向高质量发展的关键节点,研究经济增长内在动力演变对推动经济高质量发展尤为重要。文章对罗默模型(即内生经济增长模型)进行改进,将资本、知识和劳动三大要素作为经济增长的内在动力,在此基础上构建要素的增长方程以及经济系统稳定状态分析模型。文章选用2000-2017年陕西省经济建设数据进行实证,测算内在动力的增长率、贡献率,并分析陕西省经济系统的稳定状态。研究表明:资本要素仍是经济增长的主导动力;随着时间的变化,资本要素的比重逐渐降低,知识和劳动在经济增长中发挥着越来越重要的作用。未来很长一段时间内,陕西省经济增长的增长点更多地要依靠优化资本要素配置、以科技创新为核心的知识要素,以及高质量的劳动力水平。China is at a critical point in which the economy shifts from high-speed development to high-quality development.It is particularly important to study the evolution of the internal dynamics of economic growth to promote high-quality economic development.The article improves the Romer model(the endogenous economic growth model),and takes the three major factors of capital,knowledge,and labor as the internal driving force of economic growth,and builds the growth equation of factors and the analysis model of the stable state of the economic system on this basis.The article selects the economic construction data of Shaanxi Province from 2000 to 2017 for empirical analysis,calculates the growth rate and contribution rate of intrinsic power,and analyzes the stable state of the economic system of Shaanxi Province.Studies have shown that capital factors are still the dominant driving force for economic growth;as time changes,the proportion of capital factors gradually decreases,and knowledge and labor play an increasingly important role in economic growth.For a long time to come,the growth points of Shaanxi's economic growth will rely more on optimizing the allocation of capital elements,knowledge elements centered on technological innovation,and high-quality labor.
