TESTING THE INDUCED INNOVATION HYPOTHESIS USING COINTEGRATION ANALYSIS
提出基于协整分析的方法检验要素价格变动是否影响技术创新方向（诱导创新假说），并应用于美国农业数据（1948-83年），结果对该假说支持不足。
This paper deals with some of the problems involved in testing the hypothesis that factor price movements tend to influence the type of technological innovations which are developed and adopted, known as the Induced Innovation Hypothesis. Previous methods to perform this test are briefly reviewed and their limitations are discussed. A testing procedure which is based on the use of cointegration analysis is proposed and its advantages outlined. Finally, one application of the method is made, providing little support for the Induced Innovation Hypothesis in the case of US Agriculture (1948–83).
