从整体和分类两个层面分别计算了园艺产品从1997-2007年的G-L产业内贸易指数、Brulhart边际产业内贸易指数、Thom&McDowell水平型和垂直型产业内贸易指数。发现我国园艺产品的整体产业内贸易水平比较低,Brulhart边际产业内贸易指数显示我国园艺产品11年来贸易的增量主要来自于产业间贸易,Thom&McDowell指数表明我国园艺产品产业内贸易中,水平型和垂直型产业内贸易所引发的贸易增量基本相当。
From the two levels of overall and classification, the G-L Intra-industry Trade Index, Brulhart Intra-industry Trade Index and Thom & McDowell Horizontal and Vertical Intra-industry Trade Index of horticultural products from 1997 to 2007 were calculated respectively. Found that the overall intra-industry trade level of horticultural products in China is relatively low. The Brulhart marginal intra-industry trade index shows that the increase of trade in horticultural products over the past 11 years mainly comes from intra-industry trade. The Thom & McDowell index shows that in our intra-industry trade of horticultural products, The trade increment triggered by vertical intra-industry trade is basically the same.
