在当前的国际贸易中,有很多人会以西方经济学中的供求理论为依据,简单的认为进口不利于本国的经济增长,出口能拉动经济发展。也就是说,大力发展出口,增加贸易顺差对于本国的经济具有正的乘数作用;反之则起到负的乘数作用。实际上,这种认为是极不准确的,贸易差额是一把双刃剑,他能使经济加速也可以让经济窒息。 In the current international trade, many people will use the theory of supply and demand in Western economics as a basis. They simply think that imports are not conducive to domestic economic growth, and exports can drive economic development. In other words, vigorously developing exports and increasing trade surplus have a positive multiplier effect on the country’s economy; on the contrary, it has a negative multiplier effect. In fact, this kind of thinking is extremely inaccurate. The trade balance is a double-edged sword. He can speed up the economy and suffocate the economy.
