The problem largely comes down to a decrease in biomedical research-and-development expenditure. As it stands, roughly $270 billion is invested in the field each year, producing an impressive half-million research publications, but only 20-30 new medicines.
这一问题在很大程度上可以归结为生物医学研发支出的下降。目前，该领域每年的投资规模大约为2,700亿美元，产生令人瞩目的五十万项发表成果，但只能带来20—30种新药。
