摘要

围绕股票市场对外开放带来的收益和回报,本文利用双重差分法和倾向得分匹配法研究沪港股票交易互联互通机制(以下简称沪港通)和深港股票交易互联互通机制(以下简称深港通)的实施对企业创新投入的影响.结果发现,研究样本中,入选沪港通和深港通标的的上市企业创新投入水平更高.进一步研究发现,股票市场对外开放通过缓解企业的融资约束、提高股票流动性和增加风险分担三个渠道提升了上市企业创新投入水平.异质性分析结果显示,成为沪港通和深港通标的的非国有企业表现出更高的创新投入水平;进入机制内的上市企业应收账款占比显著下降,即股票市场对外开放提高了上市企业现金流的稳定性,这可能是企业增加创新投入的原因之一.

Abstract

Focusing on the benefits and returns brought by the opening-up of the stock market,this paper adopts the difference-in-difference method and the propensity score matching method to estimate the impact of the implementation of the Shanghai-Hong Kong Stock Connect and Shenzhen-Hong Kong Stock Connect on corporate innovation investment.The findings reveal that the listed companies selected as the targets of the Shanghai-Hong Kong Stock Connect and Shenzhen-Hong Kong Stock Connect show a higher level of innovation investment.Further research finds that the opening-up of the stock market to the outside world has improved the innovation investment of listed companies through three channels:easing corporate financing constraints,improving stock liquidity and increasing risk sharing.Heterogeneity results show that,non-state-owned enterprises that have become the targets of the Shanghai-Hong Kong Stock Connect and Shenzhen-Hong Kong Stock Connect increase their innovation investment more significantly.The proportion of corporate accounts receivable has dropped significantly,that is,the opening-up of the stock market to the outside world has improved the stability of the cash flow of listed companies,which may also be one of the reasons for increased investment in innovation.
