保护主义理论要求国家进行干预，以实现对外贸易的平衡。保护主义的目的在于影响贸易差额并纠正逆差，因为出口与进口之间的自发平衡无法实现均衡，也无法纠正逆差。因此，保护主义是必要的，这也正是征收关税以及实施进出口限制的原因。

The protectionist theory requires that a State interferes in order to achieve equilibrium in foreign trade. The pupose of protectionism is to influence the balance of trade and redress the deficit, because the spontaneous balance between exports and imports would not be able to achieve equilibrium, nor would it be able to redress a deficit. Therefore, protectionism would be necessary, and that is why custom duties as well as export and import restrictions would be imposed.

这一理论就其现状而言存在局限，因为它将国家的干预权限仅限于实现对外贸易平衡或弥补赤字。这是错误的，因为伊斯兰国家进行干预，是为了与其他国家进行对等往来，满足国家的需求，以获取货币收入和外汇，最重要的是，传播伊斯兰的呼声。因此，将国家的干预局限于实现贸易交易的平衡和弥补赤字，是不恰当的。相反，国家的干预应当服务于政治、经济和商业目标，并承载伊斯兰的使命。

This theory as it stands is limited, because it restricts the State’s powers to interfere merely to achieve a foreign balance of trade or to redress the deficit. This would be wrong because the Islamic State interferes in order to deal with the other states with reciprocity, to provide the country’s needs to generate monetary gains and foreign currencies and, most importantly, to carry the call for Islam. Therefore, it would be wrong to confine the interference of the State to achieving equilibrium in trade transaction and to redress the deficit. Rather, her interference should be for political, economic and commercial aims and for carrying the Islamic Message.
