摘要： 为了研究青海省近年来经济发展中资本、劳动和科技进步因素的作用，分析其经济发展的动力源泉，根据2002—2012年青海省统计公报，利用柯布-道格拉斯生产函数对青海省经济增长的贡献因素进行分析。青海省是一个资源大省，其区域经济和产业经济发展不均衡。2009年以后，青海省的经济增长对投资的依赖过高，科技进步的作用有所削弱，甚至出现了副作用。青海省的固定资产投资相对规模远远高于国内水平，资金主要来源于国内，外商投资所占的比重很小，投资的主要去向是第二、第三产业。所以建议青海省以后加大科技方面的投入，加强对外贸易，加快人才培养和引进，调整产业格局，依托资源优势和区位优势发展特色产业和资源深加工产业以改变目前的支柱产业格局，促进青海省经济的良性发展。
