Vertical Production Networks in Multinational Firms
利用美国跨国企业数据，研究母公司与其海外子公司之间的中间投入品贸易，发现子公司面临更低贸易成本、低技能劳动力工资和公司所得税率时，对进口投入品的需求更高。
In recent decades, growth of world trade has been driven largely by rapid growth of trade in intermediate inputs. Much of input trade involves multinational firms locating input processing in their foreign affiliates, thereby creating global vertical production networks. We use firm-level data on U.S. multinationals to examine trade in intermediate inputs for further processing between parent firms and their foreign affiliates. Among our main findings are that demand for imported inputs is higher when affiliates face lower trade costs, lower wages for less-skilled labor, and lower corporate income tax rates. © 2005 President and Fellows of Harvard College and the Massachusetts Institute of Technology.
