高新技术企业认定是我国政府激发企业创新活力、提升企业研发积极性的一大举措。本文基于2007-2018年A股上市公司的面板数据，对高新技术企业认定对企业研发投入的影响进行了分析，同时考察了寻租因素对该影响的调节效应。通过实证发现：高新技术企业认定确实能够提升企业研发投入力度，且高市场化地区的促进作用强于低市场化地区；寻租行为的产生会抑制这种促进作用，且对低市场化地区企业的抑制效应更明显；短期性的政策迎合式的投入是高新技术企业认定提升企业研发投入的一大因素，且低市场化地区的企业研发投入水平与高新技术企业认定年份的正相关关系更加显著。我们建议，要进一步完善高新技术企业认定的程序和办法，同时要提升市场化水平，激发企业自主创新和研发投入的主动性。

The identification of high-tech enterprises is a major measure for the Chinese government to stimulate the innovation vitality of enterprises and enhance the enthusiasm of R&D. Based on the data of A-share listed companies, this paper analyzes the impact of high-tech enterprise recognition on R&D investment by using panel data from 2007 to 2018, and examines the adjustment effect of rent-seeking factors on this impact. Through empirical discovery: high-tech enterprises can indeed enhance the R&D investment of enterprises, and the promotion effect of high-market areas is stronger than that of low-market areas; the generation of rent-seeking behavior will inhibit this promotion, and enterprises in low-market areas The suppression effect is more obvious; the short-term policy catering to the investment is a major factor for high-tech enterprises to enhance the R&D investment of enterprises, and the positive correlation between the R&D investment level of low-market areas and the high-tech enterprise recognition year is more significant. We suggest that we should further improve the procedures and methods for the identification of high-tech enterprises. At the same time, we must raise the level of marketization and stimulate the independent innovation and R&D investment of enterprises. Initiative.
