aggregation problem造句

• Further study on the aggregation problems of mainstream macroeconomic theory
  再论主流宏观经济理论中的总量问题
• The wage unit is another way to solve the aggregation problem , but the aggregation by this way represents the value relation in the money economy system rather than the gross of actual goods
  但由此得到的经济总量并非实物的加总，而是体现了货币经济体制下的价值关系。
