摘　　要：一般认为,中国的出口加工业大量使用国外中间投入品,本国技术含量很低。但是,这一观点并未得到系统验证。产品国内技术含量概念的首次提出,以及基于投入—产出表的新测算方法,使全国及江苏省、广东省出口品的国内技术含量得以检验,结果发现,1997—2002年间全国以及江苏省的出口品国内技术含量迅速下降,而且全部技术含量也没有显著提高;广东省的出口品国内技术含量在1992—2002年间呈现先下降、后上升的V型变化。据此,我们推测中国出口品国内技术含量水平的下降可能只是一个暂时现象。It is generally believed but has not yet been systematically demonstrated that China's export processing sector imports large quantities of intermediate investment goods from overseas, but has very low domestic technological contents (DTC). Using our original concept of DTC and a new method of calculation based on input-output tables, this paper examines the DTCs of exports from Jiangsu and Guangdong provinces and China as a whole. We find that during the period 1997—2002 the DTCs of exports from Jiangsu province and China as a whole decreased rapidly, and no noticeable rise was observed in their whole technological contents (WTC). However, in the period 1992—2002 the DTCs of exports from Guangdong Province showed a V curve, i.e., first falling then rising. Taking these findings together, we conclude that the decline of the DTCs of China's exports is probably a temporary phenomenon.
