Is financial structure (FS) valuable to economic performance (EP) of countries? To answer this question, we investigated 23 oil‐producing and 18 non‐oil‐producing countries over the course of ten years (2006–2015). We found an increase in bank‐based FS decreases economic growth (EG) and amplifies growth volatility (GV) in the oil‐ and non‐oil‐producing economies. An increase in market‐based FS increases EG in the two samples but amplifies GV in the oil‐producing economies while dampening GV in the non‐oil‐producing countries. The uniqueness in our results is that between the oil‐ and non‐oil‐producing countries, where the relationship between FS and EP is negative, the negative effect is more in the oil‐producing countries. Where the relationship is positive in the two samples, the positive effect is smaller in the oil‐producing countries. We, therefore, recommend that any policy reforms in the oil‐producing economies should be context‐specific because oil‐producing economies appear to differ from the other economies.

石油生产国的金融结构对经济绩效的价值

金融结构（FS）对国家的经济绩效（EP）是否有价值？为了回答这个问题，我们在十年（2006-2015年）的时间内调查了23个产油国和18个非产油国。我们发现，以银行为基础的金融服务的增加会降低石油和非石油生产经济体的经济增长（EG）并放大增长波动率（GV）。以市场为基础的FS的增加使两个样本的EG均增加，但在石油生产经济体中的GV扩大了，同时抑制了非石油生产国家的GV。我们的研究结果的独特之处在于，在石油生产国与非石油生产国之间，FS和EP之间的关系为负，而负面影响在石油生产国中更大。如果两个样本之间的关系是正的，则在产油国的正效应较小。我们，
