中文摘要：

本文利用2002-2012年中国分省面板数据,借助于随机前沿模型和空间面板计量模型对各省域研发全要素生产率的空间溢出效应及其地理距离特征进行了分析。研究发现：中国研发全要素生产率呈现显著的空间溢出效应,且溢出效应随着时间推移不断加强,而随着地理阈值增加不断衰弱;东部地区研发全要素生产率的空间溢出效应最大,中部地区次之,西部地区最低;从全国范围来看,无论是智力资本投入还是物质资本投入均能显著提升研发全要素生产率;从分区域来看,物质资本对东部地区研发全要素生产率的驱动空间接近消失,而中、西部地区存在智力资本存量不足和层次偏低的问题。

英文摘要：

This paper analyzes the spillover effect of R＆D total factor productivity and its geographical distance characteristic by means of SFA model and spatial panel econometric model using provincial data in China from 2002 to 2012. The results show that China＇ s R＆D total factor productivity shows a significant spillover effect, and with the passage of time, the spillover effect contin- ues to strengthen, however, it keeps dwindling when increasing geographical threshold. Spillover effect of R＆D total factor produc- tivity in Eastern Region is the highest, which is followed by Central Region and Western Region. Both physical and intellectual in- put can significantly improve R＆D total factor productivity in China. However, from sub - regional perspective, physical capital cannot promote R＆D total factor productivity any more in the Eastern Region, and there lacks sufficient and excellent intellectual input in the Central and Western Region.
