This study examines how financial development influences economic complexity, using a broad index of financial development. By utilising a global sample of 86 countries over the period 2002–2017 and applying several econometric techniques, we find that financial institutions and financial markets, as well as their sub-indices (financial depth, financial access and financial efficiency), have significantly positive impacts on economic complexity. Interestingly, financial institutions have a stronger effect than financial markets, and it is the same with financial efficiency over financial access and financial depth. Three subsamples comprising 28 low- and lower-middle-income countries, 22 upper-middle-income countries and 36 high-income countries are examined.

为经济融资：金融发展对经济复杂性的多方面影响

这项研究使用广泛的金融发展指标研究了金融发展如何影响经济复杂性。通过利用2002-2017年期间86个国家/地区的全球样本并应用多种计量经济学技术，我们发现金融机构和金融市场及其子指数（金融深度，金融准入和金融效率）具有显着的正向影响对经济复杂性的影响。有趣的是，金融机构的影响要强于金融市场，在金融准入和金融深度上的金融效率也是如此。对三个子样本进行了调查，包括28个中低收入和下中等收入国家，22个中上收入国家和36个高收入国家。
