Sources: ZDGN-D and ZdGn (various years): ZDB (5 March 1996 p 4) and Jiang(1993)are among the very few studies in the literature that deal with this topic, both covering mainly the second half of the 1980s. The results which they have obtained do not agree with each other, largely due to their different estimation methodologies as well as different ways of aggregating data in the attempts to achieve correspondence between trade and production categories. A further shortcoming that might serIous sly limit the usefulness of such studies concerns the comparability of the capital stocks of different industries. It is a salient feature of China's manufacturing sector that some industries(e. g, electronics) are much newer than others. As a result, the value figures of capital might obscure the fact that capital productivity differs widely across industries, especially because of problems of pricing and depreciation that are inherited from the pre-reform era. In any event, it can be seen from Table 3 that the capital-labour ratio of the mechanical and electronics industry and that of he electronics industry alone have both outstripped the manufacturing sector as a whole, and, in the latter case, the gap has widened over time able 4 presents an alternative measure that is simple yet effective in indicating the relative capital and technology intensity in production: the per worker net output value of the mechanical and electronics industry, the electronics industry, and the manufacturing sector as a whole. For the mechanical and electronics industry, its abour productivity has been close to the manufacturing sector average. In the case of he electronics industry alone, its labour productivity has persistently outstripped the manufacturing sector by a wide margin since the mid-1980s. These reinforce the refutation of the argument that the industries under consideration might be more labour-intensive than the rest of the manufacturing sector.
