我院教师在经济学期刊发表论文

2021年4月，我院助理教授田津菁与首都经贸大学助理教授王钛宁、美国西弗吉尼亚大学教授Joshua Hall合作的论文 "The Effect of Exports on Labour Share: A Semiparametric Approach Using Chinese Manufacturing Panel Data" 在经济学期刊The World Economy 在线发表。

该论文将出口对劳动报酬占比的影响区分为直接和间接影响，这一区分改变了现有文献中影响劳动报酬占比关键因素的边际效应。现有文献广泛研究了出口的直接影响，但潜在的间接影响却鲜有研究。该论文采用1998年至2007年中国微观层面企业数据，运用可变系数的固定效应模型，揭示潜在的非线性关系，降低模型错误设定的风险。同时，此模型利用序列向后拟合的核估计量进行估计，易于运算且更为有效。本文发现，虽然出口对劳动报酬占比有直接的正向影响，但出口也会通过强化公司资本密集度、垄断势力及偏向资本带来的技术进步等因素的负面边际影响，间接减小劳动报酬占比。因此出口对于劳动报酬占比的最终影响并非有益，且这一影响因公司特征、所在地区以及所处时期不同而变化。

Assistant Professor Jinjing Tian's Paper Published in The World Economy

Jinjing Tian, IAER Assistant Professor, published her paper in The World Economy in April 2021. Entitled  "The Effect of Exports on Labour Share: A Semiparametric Approach Using Chinese Manufacturing Panel Data", the paper was co-authored with Taining Wang, Assistant Professor at Capital University of Economics and Business, and Joshua Hall, Professor at West Virginia University.

The paper distinguishes the effects of export on labour share into a stand-alone direct effect and indirect effects, which alter the marginal impact of three key determinants of labour share found in the literature. While the direct effect of export has been extensively studied, the potential indirect effects remain unexplored. The paper investigates both effects of exports using micro-level Chinese firm-level data from 1998 to 2007. A fixed-effect varying coefficient model is employed to reveal the potential nonlinearity of the effects of exports while alleviating the risk of model mis-specification. The model is estimated by a spline backfitted kernel estimator, which is more efficient and computationally attractive than alternative estimators. The paper finds that while exports directly increase labour share as expected, it declines labour share indirectly through intensifying the negative marginal impact of firms' capital intensity, monopoly power and capital-augmented technological progress on labour share. As a result, the net effect of exports is not beneficial to labour's share of income and varies in magnitude across firm characteristics, regions and time periods.
