贸易成本、异质性企业与扩大内需:理论框架与中国经验

扩大内需是现阶段稳定我国经济增长的关键因素之一。在现有异质性企业模型的基础上,本文通过建立一个异质性企业选择模型阐述了贸易成本对内部需求的影响机制。该模型表明贸易成本是影响企业国内外市场选择行为的关键因素,政府可以通过调节企业的相对贸易成本来实现扩大内部需求的目标。同时利用我国工业企业层面的数据,对模型进行了实证检验,检验结果符合理论模型的基本预测。

Trade Costs,Heterogeneous Firms and Expanding domestic demand:Theory and Evidence from Chinese Manufacturing Firms

It’s of vital importance to expand domestic demand for the time being.Based on the existing heterogeneous firm models,this paper proposes a heterogeneous firms’ sorting model,which states the influencing mechanism that the trade costs exert on the domestic demand.The model indicates that trade costs is the key factor for the firm’ s sorting pattern,and the government can reach the target of expanding the domestic demand by adjusting the relative trade costs of heterogeneous firms.Using the Chinese manufacturing firm-level data,we provide evidence consistent with the model’s predictions.
