Using the panel data of small and medium-sized board listed companies in China’s A-share market from 2021 to 2024, this research applies the input-oriented DEA-BCC model to measure the technical efficiency at the company level and then adopts the industry-annual two-way fixed effects model to examine the influence of management information system investment on the technical efficiency of small and medium-sized enterprises. We find that the investment in the management information system significantly restrains the technical efficiency: an increase of one standard deviation in the investment intensity will lead to the efficiency decreasing by 0.0431 units, which is equivalent to 13.34% of the sample mean and this confirms that there is a productivity paradox in the digital transformation of small and medium-sized enterprises which is analogous to the classic Solow Paradox at the corporate level. This inhibitory effect is more obvious in small-scale, high-leverage, low-profitability companies, which shows that resource endowments and risk-resistance capabilities are indeed the key boundary conditions. This research not only provides micro-empirical evidence for the research regarding the digital transformation of small and medium-sized enterprises but also produces practical reference materials for enterprises and policymakers.
