中文摘要：

运用我国1988-2008年省级面板数据，以全要素生产率体现经济增长方式，考察不同类型专利对经济增长方式的影响，结果凸显以1997年为断点的阶段性差异。实证结果显示，发明专利在1997年前对全要素生产率没有显著影响，但在1998-2008年对全要素生产率的影响远大于实用新型和外观设计专利，论证了原创型创新对现阶段我国经济增长方式转变的重要性，这与现有研究的结论不同。

英文摘要：

Using panel data of different provinces in 1988-2008, we do the empirical study about the effect of various patents on total factor productivity to explore patent＇s influence on China＇s economic development mode, we find the year of 1997 is a breakpoint. Our empirical research shows： invention patent doesn＇t have significant effect on total factor productivity before 1997, whereas the effect of invention patent＇s is much lager than utility model patent and design patent in 1998--2008. The article demonstrates the importance of original innovation for China＇s economic development mode change at present stage, which is different from former studies.
