贸易自由化对研发技术进步影响的异质门槛效应

Heterogeneous Threshold Effect of Trade Liberalization’s Impact on R

摘要:

本文基于2004～2011年中国工业行业33个细分行业的面板数据,采用门槛回归技术,实证研究了贸易自由化对研发技术进步影响的异质门槛效应。研究表明：(1)贸易自由化与研发技术进步呈倒“N”型的非线性关系,即随着贸易自由化水平由低变高,其对研发技术进步会产生先降低后提高再降低的影响规律；(2)贸易自由化的研发技术进步效应还取决于市场化水平、外商直接投资等影响,在环境规制、外商直接投资及行业利润门槛条件下,贸易自由化对研发技术进步的影响总体呈负向效应,而在市场化水平门槛条件下呈倒“U”型特征,在企业规模门槛条件下呈“U”型特征。(3)不同门槛条件下,贸易自由化对研发技术进步的门槛效应存在明显的行业异质性特征,其中具有负向影响的行业分布较为集中。

Abstract:

this article is based on the Chinese industry from 2004 to 2011 in 33 subdivision industry panel data, using threshold regression techniques, the empirical study on the impact of trade liberalization on r d technology progress heterogeneous threshold effect. Research shows that: (1) trade liberalization and development of technological progress is “N” model of the nonlinear relationship, namely with trade liberalization level from low to high, the research and development technology produces lower after improve to reduce the influence of the first law; (2) research and development technology progress effect of trade liberalization also depends on the level of marketization, foreign direct investment effect, such as in environmental regulation, foreign direct investment and industry profits threshold conditions, trade liberalization impact on r d technology progress are negatively to the overall effect, and under the condition of marketization level threshold is inverted “U” type characteristic, under the condition of enterprise scale threshold is “U” type feature. (3) under the condition of different threshold, trade liberalization on the threshold of the r d technology progress effect obvious heterogeneity characteristic industry, which has a negative impact of industry distribution is concentrated.
