中文摘要：

本文利用我国各省份2000-2010年的面板数据，使用空间计量经济学的相关理论研究了我国各省份R＆D投入对经济增长的作用途径问题。本文首先建立了包含省份之间地理空间距离和经济距离的空间权重矩阵．然后利用空间滞后模型和空间误差模型分别研究了R＆D投入对各省份经济增长的空间溢出效应。研究结果表明我国各省份经济增长之间存在着高度的空间相关性，从国家创新体系的角度来看，一个省份的R＆D投入能够通过四条途径作用于整个国家的经济增长，其中一条是直接影响，一条是间接影响，另外两条是通过空间溢出形成的间接影响。

英文摘要：

In order to analysis the pathways of Chinese provinces R＆D investment and economic growth, the paper uses spatial econometric model based on Chinese province＇s panel data between 2000 and 2010. The paper redefines spatial weight matrix including economic and geographical distance factor. Meanwhile,it researches the spatial spillover effect of R＆D investment and economic growth based on SAM and SEM, and finds that the provincial economic growth has an obviously spatial correlation. From the point of view of the national innovation system,a province＇s R＆D investment can affect the whole nation economic growth through four ways, the first way is direct affect, the second is indirect way, and the other two ways are indirect affect based on spatial spillover.
