本文考察了贸易自由化对工厂规模、生产运行时间和产品多样化的影响。我们首先开发了一个具有多个产品工厂的差异化产品贸易模型。然后，我们使用一大批加拿大制造工厂及其在1989年加拿大-美国自由贸易协定(FTA)中的经验，提出了经验证据。该模型预测，双边关税降低降低了出口工厂的产品多样化，增加了生产运行时间，并对这些工厂的规模产生了模糊的影响。它还减少了非出口工厂的产品多样化和规模，对这些工厂的生产运行时间没有影响。关于非出口植物的经验证据为该模型提供了广泛的支持。关于出口植物的证据表明，出口商减少了产品多样化，增加了生产周期和工厂规模，但这些变化似乎与关税削减无关。一旦进入出口市场，工厂就会对关税削减以外的力量做出反应。进一步削减关税对这些工厂的影响较小。
This paper examines the effect of trade liberalization on plant scale, production-run length and product diversification. We first develop a model of trade in differentiated products with multiproduct plants. We then present empirical evidence using a large panel of Canadian manufacturing plants and their experience with the 1989 Canada-U.S. Free Trade Agreement (FTA). The model predicts that the bilateral tariff reduction reduces the product diversification of exporting plants, increases the production-run length and has an ambiguous effect on the size of those plants. It also reduces the product diversification and size of non-exporting plants, and has no effect on the production-run length of those plants. The empirical evidence on non-exporting plants provides broad support for the model. The evidence on exporting plants shows that exporters reduce product diversification, and increase production-run length and plant size, but those changes do not appear to be related to tariff cuts. Once in the export markets, plants respond to forces other than tariff cuts. Further tariff cuts have less effect on those plants.
