This study examines the trade-led growth (TLG) hypothesis for the Kingdom of Saudi Arabia. Using time-series annual data for the period 1985–2019, the ARDL approach and Toda-Yamamoto Granger causality test are applied to accomplish the study. The ARDL estimation reveals that trade openness positively causes economic growth in both the long and short run, and the TLG hypothesis is found valid for the Kingdom. The Toda-Yamamoto Granger causality test results have evidenced several unidirectional causalities. Of them, trade openness causes economic growth and supports the ARDL finding and hence the TLG hypothesis for the Kingdom. Moreover, trade openness causes gross fixed capital formation, and the labor force stimulates both economic growth and trade volume. The findings recommend that the Kingdom may increase its trade to reap further benefits and enhance its income growth.

这项研究检验了沙特阿拉伯王国的贸易主导型增长（TLG）假设。利用1985-2019年期间的年度时间序列数据，应用ARDL方法和Toda-Yamamoto Granger因果关系检验完成研究。ARDL估计表明，贸易开放长期或长期都会对经济增长产生积极影响，并且发现TLG假设对沙特阿拉伯是有效的。Toda-Yamamoto Granger因果关系检验结果证明了几个单向因果关系。其中，贸易开放导致经济增长，并支持ARDL的发现，从而支持王国的TLG假设。此外，贸易开放会导致固定资本形成总额，劳动力会刺激经济增长和贸易量。
