摘要
从价值链视角探究贸易自由化对R&D创新效率影响的非线性特征。基于门槛回归技术法,实证分析2004—2011年工业行业贸易自由化对R&D双环节效率的非线性影响。结果表明:贸易自由化对R&D双环节效率的作用机理没有本质区别,即二者的门槛效应在市场化水平门槛条件下都呈倒"U"型特征,在环境规制水平、规模化水平、获利能力及工资水平门槛条件下都呈"U"型特征;但是,二者的门槛效应也存在一定的条件性差异,即在外商直接投资水平门槛条件下,贸易自由化对R&D转换效率的门槛效应呈倒"N"型特征,而对R&D转化效率的门槛效应则呈倒"U"型特征;根据门槛条件,对行业进行分类发现,贸易自由化对R&D双环节效率具有负向影响的行业分布较为集中,主要原因是世界经济衰退带来的外部环境恶化。
Based on threshold regression techniques, the article studies the threshold effect of trade liberalization on R＆D dual - link efficiency from 2004 to 2011. Empirical research suggests that there is no essential difference between the two threshold effects of trade liberalization on R＆D dual - link efficiency. The threshold effect in the market conditions are tested inverted ＂U＂ - type characteristics as well as environmental regulation, the level of large - scale levels, profitability and wage. However, the two threshold effect exists certain difference, that is, in foreign direct investment levels threshold conditions, the threshold effect is inverted ＂N＂ - type features, while in the R＆D conversion efficiency conditions is inverted ＂U＂ shape characteristics. According to the threshold conditions, the industry is more concentrated in the interval range where trade liberalization on R＆D dual link has a negative effect, mainly due to the world economic recession.
