In the present study, five stylized facts about China ＂s producer services are established through international, intersectoral and intertemporal comparisons based on input --output tables. First, the overall service input ratio is the lowest in all the sample economies. Second, most producer services are supplied by the traditional labor-intensive sectors. Third, manufacturing is the biggest user of producer services, and service industry is the second, while the opposite is true for most of the other sample economies. Fourth, unlike other economies, China ＂s ＂R＆D＂ is characterized more by consumer services than producer services. Fifth, China has fairly lower service input ratios in almost all the industries. The backward and forward linkages coefficients are both smaller for ＂real estate activities＂ and ＂finance and insurance. ＂＂ Policy reform should focus not only on specific producer services but also on reducing obstacles that are inhibiting the balanced development of diverse producer services that will help China to optimize its economic structure.
Using matched firm-level trade and production data over the period 200~2006, we study the produet-destination portfolio and dynamics of Chinese industrial exporters and make a thorough comparison among four types of frms and between two kinds of trade modes. We find that ownership structure and trading modes do matter to the destination and product mix choices of Chinese industrial exporters. In particular, foreign frms＇ exports and processing trade tend to be more destination-specific and products are more specialized. Therefore, foreign firms are more likely to maintain a partieular link within a specific＇ global supply chain.
