Hybrid Rice Innovation in China: A Study of Market-Demand Induced Technological Innovation in a Centrally-Planned Economy
以中国杂交水稻创新为例，检验Griliches-Schmookler假说在计划经济中的有效性，发现水稻种植面积是决定各省水稻研究资源分配和杂交水稻采用强度的主要因素。
This paper uses the innovation of hybrid rice in China as a case study to test the validity of the Griliches-Schmookler hypothesis of market-demand-induced technological innovation in a centrally planned economy. The empirical evidence indicates that the size of rice acreage in a province is the major factor in determining the amount of resource allocation for rice research and the adoption intensity of hybrid rice in that province. This evidence is consistent with the implication of the Griliches-Schmookler hypothesis. Copyright 1992 by MIT Press.
