경제성장에 따라 수출가격의 하락이 불가피할 수도 있지만, 독점적 경쟁 무역이론은 수출가격 하락 및 교역조건 악화에 대응하기 위해서는 새로운 상품을 개발 및 수출하여 상품 다양성을 확보하는 것이 중요하다고강조한다. 이와 관련하여 본 연구는 중국이 수출가격 하락에 대응하여얼마나 다양하고 차별화된 상품을 수출해 왔는지 분석한다. 본 연구의결과에 의하면, 중국의 수출품 다양성과 차별화 효과를 반영하는 수출가격지수와 통상적 수출가격지수의 격차는 수출가격이 하락하기 시작한2002년 이후 커졌다. 중국은 수출가격 하락에 대응하기 위해 수출품의 다양성을 확보해 왔다.
Abstract
The standard international trade models predict that economic growth induces decreasing export price. Unlikely the standard assumption of one good per country, the new theoretical approach by Krugman(1980, 1989), and Helpman and Krugman(1985) takes account into varieties of goods to be produced in each country. This paper uses a proper modeling for quantifying the impact of export variety on an exact export price index, in which this paper derives an exact export price index with a conventional export price index and an effect of variety. Measuring the adjustment effect of variety requires that the elasticity of substitution be estimated. To estimate the elasticity of substitution, this paper will derive an import demand equation. Because of the simultaneous bias and measurement errors from using unit value instead of price, this paper adopts the Generalized Method of Moments, suggested by Feenstra (1994). This paper shows that China has avoided decreasing export price through increasing export varieties. The decreasing export prices have been recovered by increasing export varieties.
