Thus, various policy proposals have been submitted by some scholars. The author holds that whatever form it may take, reducing trade surplus would harm China’s economic development. On the other hand, it is difficult to boost domestic consumption by increasing the resident spending on food, clothing etc. In order to consolidate the policy of domestic demand, it is important to separate production and non-production investment and create better economic conditions by accelerating the development of non-production investment and increasing the supply of "housing, traveling and education" related consumption.展开更多
