  "question": "In 2022, to verify the hypothesis that there is a clear relationship between enterprise total assets and invention patent count in the Consumer Electronics and Electrical Industry, we focus only on provinces with high R&D density (provinces where the mean R&D investment ratio in provincial industry aggregate data exceeds the corresponding national industry aggregate mean). Among all listed enterprises in this industry within these provinces, what is the Pearson correlation coefficient between enterprise total asset scale and annual China invention patent applications?",
  "guidelines": "Answer format: numeric value (rounded to 4 decimal places). If relevant data cannot be found, please answer \"No relevant data found\"",
  "answer": "0.8294",
