Using IPO suspensions unexpectedly adopted by Chinese regulators, we examine the impact of IPO activities on the performance of local private SMEs. SMEs in regions affected by IPO activities experience reduced ROA compared to those in unaffected regions, indicating a grabbing effect of local IPO activities. Channel tests reveal that IPO firms grab customers, financial capital, and labour from local SMEs. This effect is stronger when SMEs rely heavily on financial or human capital, when IPO firms hold stronger relative power, and when competition is intense. Our findings remind regulators of the unexpected negative externalities of local IPO activities.
