摘要
文章在剖析现有部门外贸依存度公式基础上,用非竞争型投入产出模型重构部门外贸依存度公式。新公式克服了现有公式不能反映任一部门对其它部门外贸依赖性的缺陷。继而用新公式测算我国部门外贸依存度,与现有公式的结果相比较并进行跨国比较。结果表明,由于考虑了部门间的依赖性,新公式能准确测算部门外贸依存度;尽管我国总外贸依存度不高,但部门间的差异较大;除了传统因素,还有部门间的前向关联度可影响部门依存度。
This paper first analyzes the defects of the existent formula of the sector＇s dependence on foreign trade,and then utilizes the non-competitive input-output model to reconstruct the formula that reflects one sector＇s dependence on other sectors＇ foreign trade.Then,it uses the new formula to measure the actual sector＇s foreigntrade dependence,which is contrasted with the result acquired by using the existent formula and those found in other countries.The empirical results show that the new formula＇s measurement is precise;some sectors＇ dependence on foreign trade is high although the total foreign trade dependence is moderate;apart from traditional factors,inter-sector forward linkage can influence sector＇s dependence on foreign trade.
