主题：Cost and Product Advantages: A Firm-level Model for the Chinese Exports and Industry Growth

 

摘要：We estimate the unobservable demand and cost advantages of firms. We call a product advantage the extent to which a firm sells more units than its competitors at a given price. The most important cost advantage is the unobservable productivity that allows the firm to produce at a different unit cost than its competitors. We do not know the precise source of the unobservable demand advantages as we do not know it for productivity. But we show that using firm-level data on their domestic and export markets these advantages can be identified and estimated. Then we characterize the spectacular growth of China exports and industry re-structuring, with data from 1998 to 2008. Entrant and young firms show cost but no demand advantages, older firms demand advantages, and state owned firms less productivity. Demand advantages are associated to skilled labor and higher pay. R&D performing firms show great demand advantages but at the expense of sharp cost disadvantages. The joint distribution of cost and product advantages shows a strong negative correlation between both advantages. Firms tend to compete either in cost or in product attractiveness. Exports are strongly linked to cost advantages but there is an important and growing fraction linked to technologically developed products.
