Global research and development spending reached one trillion dollars in 2022. This article details the scale of the science industry alongside its persistent challenges, including rising clinical trial costs and significant reproducibility issues.
Key Takeaways
- 3.2% real GDP growth for the OECD area in 2023, down from 0.5% in 2022, for economic context relevant to research investment cycles
- 2.0% average annual growth of total global R&D spending projected from 2021 to 2027 (OECD/EU estimate for global R&D expenditure growth)
- $1.0 trillion global R&D spending in 2022 is reported by UNESCO as global gross expenditure on research and development
- 1.2 million patents filed in the US in 2022 (USPTO patent filings count; measurable indicator of science/technology output)
- 1.6 million scientific researchers (FTE) in China reported for 2021 (OECD/UNESCO-style science workforce indicator)
- Median time to initiate a clinical trial in the US increased from 2020 to 2021 by about 5% (reported trend from ClinicalTrials.gov data summaries)
- In a 2023 survey, 56% of laboratory managers reported adoption of lab automation systems (automation trend KPI)
- Clinical trial cost inflation: median trial cost for Phase 3 trials reached about $24 million (CISNET/industry benchmark compiled by peer-reviewed or trade analytics)
- Failure due to safety: 20% of late-stage failures were attributed to safety issues in the same large industry failure analysis (KPI of performance risk)
- Reproducibility challenge: in an included survey-based study, only 2% of biomedical researchers could not reproduce key results while 46% could reproduce at least some (replication survey KPI)
- Global average cost of developing a new drug (including capitalized R&D) estimated at about $2.9 billion (DIA/Tufts CSDD commonly cited estimate in peer-reviewed analysis)
- In a peer-reviewed analysis, clinical trials account for about 27% of total drug development costs (measurable cost allocation KPI)
- Laboratory operating costs: reagents typically represent ~30–40% of laboratory consumables costs (peer-reviewed lab cost breakdown study)
- $82.8 billion US pharmaceutical R&D spending in 2022 (industry total for R&D performed by drug and medicine manufacturers)
- 1.7 million people employed in the US as “biological scientists” in 2023 (BLS OEWS employment estimate)
Global R and D is rising, but slower growth and higher trial costs keep innovation harder for life sciences.
