本文利用股权分置改革作为自然实验来研究资本市场配置效率对中国上市公司劳动收入份额的影响.股权分置改革一方面会激励管理者通过"高薪引才"来应对更加激烈的外部竞争,从而提高劳动收入份额;另一方面,资本流通性的增强会减少"工资侵蚀利润"现象,从而降低劳动收入份额.实证结果表明,后者的作用占据主导,改革显著降低了上市公司的劳动收入份额.进一步分析表明,改革显著降低了国有企业的劳动收入份额,对非国有企业影响不显著;改革对劳动密集型行业影响显著,对资本密集型行业和技术密集型行业影响不显著;改革显著降低了普通雇员的劳动收入份额,但并没有影响管理者的劳动收入份额.

Stroop effect can reflect the brain attention of the conflict and the interference. In order to analyze the brain cognitive activity of Stroop effect deeply, the Stroop experiment paradigm marked with steady state visual evoked potential (SSVEP) background was designed innovatively, which can get EEG data including both the event related potential (ERP) signals and the SSVEP signals. To realize this, the envelope analysis method based on Hermite filters was proposed. EEG data of ten subjects were recorded, and then the ERP signals and SSVEP signals were gotten respectively. In the time window of 400 �� 600 ms after stimulus, the ERP signal of incongruent condition was more negative than that of congruent condition. The difference between two conditions was significant statistically and mainly distributed in the prefrontal regions, which was the EEG reflection of the Stroop effect. Through the envelope analysis, it was found that the envelope of SSVEP signal declined remarkably after the stimulus. The poststimulus changes of the Alpha frequency band total envelope of the ERP signal were related with its prestimulus level. If its level before stimulus was high, it declined to the lower level after a small increase; if its level before stimulus was low, it remained to the same level after an increase. We got the further cognitive activity study of Stroop effect through the Stroop experiment paradigm marked with SSVEP background and the envelope analysis method, which also provides a reference for other cognitive experiments.
