The challenge of long-term investment cannot be resolved without attracting more diverse and private sources of finance. In 2013, institutional investors in OECD countries alone held more than $57 trillion in assets, and pension funds collected around $1 trillion in new contributions.
政府还必须为机构投资者的参与提供便利。如果无法吸引更加多元化和私人化的资金来源，就无法解决长期投资挑战。2013年，经合组织国家机构投资者所持有的资产总额高达57万亿美元以上，而退休基金新进资金就高达1万亿美元左右。
