摘　　要：本文构建了经济发展进程与基础设施投资结构变迁的理论模型，并采用1998-2013年间省际面板数据对理论模型进行了实证检验。研究表明：在经济增长水平较低时，一般性基础设施投资对经济增长激励效应更强，但对自主创新演变影响较弱；在经济增长水平较高时，科技型基础设施投资对经济增长和自主创新激励效应均强于一般性基础设施投资。因此，政府在制定基础设施投资结构变迁政策时需同时兼顾自主创新目标和经济增长目标，根据两类基础设施投资边际效应的相对大小恰当地实施基础设施投资结构变迁，以最大限度地释放经济增长潜力。This paper develops a theoretical model considering on economic development process and infrastructure investment structure changes, then tests the theoretical model by using panel data of provinces in China from 1998 to 2013 empirically. The theoretical analy- sis shows that in the low level of economic growth, general infrastructure investment has a higher incentive effect on economic growth, but a lower incentive effect on independent inno- vation. With the increasing level of economic growth, tech-oriented infrastructure invest- ment plays a vital role in promoting the economic growth, and accelerates the evolution of in- dependent innovation. Therefore, the government should take consideration of both the goals of independent innovation and economic growth while formulating the policy for the change within infrastructure investment structure, and should implement the policy properly in accordance with the relative size of the marginal effects on the two types of infrastructure investment.
