利用我国31个省份2001—2010年的面板数据,使用空间滞后模型(SLM)研究了我国区域R&D投入、空间溢出效应及吸收能力对经济增长的影响.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,一个省份的R&D投入不仅能够促进本地区的经济增长,还会通过技术溢出促进相邻地区的经济增长,同时一个地区吸收能力越强,其对该地区经济增长的影响也越大.
By using Spatial Lag Model(SLM) based on Chinese 31 province-level panel data for the year 2001-2010 , the paper researches the effect on R&D investment, spatial spillover and absorptive capability to economic growth. It is found that the provincial economic growth has an obviously spatial correlation ,and a provincal R&D investment can affect not only itself but also the other regions through spatial spillover. Simultaneously the region's a bsorptive capability directly promotes economic growth.
