中美木质林产品产业内贸易的实证研究——基于1992—2009年的进出口贸易数据

采用UNcomtrade数据库的中美木质林产品贸易数据,利用G-L指数、G-L修正指数、Aquino指数、Brülhart边际产业内贸易指数及Thom&McDowell水平型和垂直型产业内贸易指数,对1992—2009年中美木质林产品产业内贸易的水平和结构进行实证分析。结果表明:中美木质林产品产业内贸易水平总体较低,贸易方式仍以产业间贸易为主;中美木质林产品贸易的增长由产业间贸易和产业内贸易共同引发;产业内贸易方式以垂直型产业内贸易为主。

Empirical Study on Sino-US Intra-industry Trade in Wood Forest Product: Based on Statistics of Import and Export During 1992-2009

Using the data about woodforests products trade from UNcomtrade database,this paper analyzes empirically the level and the structure of Sino-US intra-industry trade in wood forest products in the period of 1992-2009 by using G-L index,modified G-L index,Aquino index,Brulhart marginal intra-industry trade index and Thom McDowell horizontal and vertical intra-industry trade index.The results show as follows：Sino-US inter-industry trade in wood forest products is still in low level,and is dominated by inter-industry trade;the growth of Sino-US trade in wood forest products is caused jointly by inter-industry trade and intra-industry trade;the vertical intra-industry trade is the main form of intra-industry trade.
