  "question": "In 2022, based on the 'high input low output' hypothesis in Romer's endogenous growth theory, verify whether state-owned enterprises in the semiconductor industry exhibit the dual anomaly of 'large asset scale but low operating profit margin' and 'high R&D investment but low patent conversion efficiency'. The hypothesis states: when state-owned enterprises rank high in the industry in both asset scale (total assets) and R&D investment (amount), their operating profit margin (operating profit / revenue) and patent conversion efficiency (cumulative China invention patent grants / R&D investment × 100 million) should rank low in the industry. Please count the number of enterprises that simultaneously satisfy the following conditions (state-owned enterprises include central state-owned enterprises, local state-owned enterprises, state-owned enterprises (research institutes), and state-owned enterprises (other)): ① total assets > median total assets of industry-wide state-owned enterprises; ② operating profit margin < median operating profit margin of industry-wide state-owned enterprises; ③ R&D investment amount > median R&D investment amount of industry-wide state-owned enterprises; ④ patent conversion efficiency < median patent conversion efficiency of industry-wide state-owned enterprises.",
