We document a set of bilateral trade data by commodity for 1962-2000, which is available from www.nber.org/data (International Trade Data, NBER-UN world trade data). Users must agree not to resell or distribute the data for 1984-2000. The data are organized by the 4-digit Standard International Trade Classification, revision 2, with country codes similar to the United Nations classification. This dataset updates the Statistics Canada World Trade Database as described in Feenstra, Lipsey, and Bowen (1997), which was available for years 1970-1992. In that database, Statistics Canada had revised the United Nations trade data, mostly derived from the export side, to fit the Canadian trade classification and in some cases to add data not available from the export reports. In contrast, in the new NBER-UN dataset we give primacy to the trade flows reported by the importing country, whenever they are available, assuming that these are more accurate than reports by the exporters. If the importer report is not available for a country-pair, however, then the corresponding exporter report is used instead. Corrections and additions are made to the United Nations data for trade flows to and from the United States, exports from Hong Kong and China, and imports into many other countries.

This paper examines the relationships between distance and the transportation costs of international trade on the location-specific effects of foreign direct invest-ment and provincial per capita income in China. Applying the economic geography model proposed by Redding and Venables (2004), it traces the increasing wage inequality among the coastal and inland provinces by focusing on the distance of foreign-owned firms from access to international markets and to suppliers of intermediate inputs. First, a gravity-type equation is used to construct the 'market access' and 'supplier access' variables. Then, the effect of market and supplier access on provincial wage rates is estimated. The results indicate that distance does affect international trade and geography explains roughly one-third of the wage differential. Greater market access increases the provincial wage gap, while larger supplier access increases the wage difference in trade destined for the foreign market but decreases the wage difference in trade targeted for the domestic market. Similar findings also result from applying the estimations to two local firm types: state-owned enterprises and collective-owned enterprises.

In this study, using market-level data on quantities, prices' and automobile characteristics from 1995 to 2001, we conduct a market analysis of the Chinese automobile industry under imperfect competition. On the demand side, we apply a nested multinomial logit model to the national market share data in order to ascertain the demand features of China's automobile market. On the supply side, we assume Bertrand behavior to uncover the markups set by automobile manufacturers. Our empirical results suggest that some large automobile manufacturers set high markups, indicating their strong market power in China's automobile market. However, their declining markups in the late 1990's imply a reduction in market control by the major producers.

Foreign-invested enterprises (FIEs) account for well over half of all Chinese exports and this share continues to grow. While the substantial presence of FIEs has contributed greatly to the recent export-led growth of China, an important objective of the Chinese government is to ultimately obtain foreign technologies and develop their own technological capabilities domestically. This paper uses detailed data on Chinese exports by sector and type of enterprise to examine the extent to which domestic enterprises are "keeping up" or even "catching up" to FIEs in the volume, composition and quality of their exports. We also use a newly-created dataset on Chinese policies encouraging or restricting FIEs across sectors to examine the extent to which such policies can affect the evolving composition of Chinese exports.

The Policy Research Working Paper Series disseminates the findings of work in progress to encourage the exchange of ideas about development issues. An objective of the series is to get the findings out quickly, even if the presentations are less than fully polished. The papers carry the names of the authors and should be cited accordingly.
