Is There"Productivity Paradox"in Sino-US Agricultural Product Trade:Test from Perspective of Value-Added Trade
In the context of global value chains,the real gains from bilateral agricultural product trade be-tween China and the US are deviated from the traditional trade statistics.This paper calculates the real trade gains between the two countries from the perspective of value-added trade and constructs a gravity model of value-added trade to explore the effect of productivity.The empirical results show that in the Sino-US bilateral agricultural product trade model,the increase in the total factor productivity significantly reduces the total ex-port volume and the total value-added exports of the agricultural product industries in both countries.In the two countries'respective foreign trade models,the total export volume is positively affected by domestic pro-ductivity.At the value-added level,there is an obvious"productivity paradox"in China and the US.The pro-motion effect of productivity in China and the US on the gains from the bilateral agricultural trade is re-flected in the export-intensive industries,that is,it is necessary for the agricultural product industries to open up more export markets and participate in the global value chain,so as to increase trade gains through trans-formation and upgrading and improving productivity.
