Focusing on the rice subsector, the adoption of two forms of rice technology--hybrid rice and double-cropping--is treated as a decision to be made by the producer. The analysis focuses on measuring the relative importance of the role of technology versus that of institutional innovation. A six equation rice sector model explaining provincial-level technology adoption, yield, and factor demand are econometrically estimated using a unique time series, cross section data set from China's 13 rice growing provinces for the period 1975-90. Growth decomposition analysis identifies technology adoption as the most important determinant of rice yield growth during the early reform period, 1978-84 accounting for nearly 40 percent the change; institutional reform accounted for 35 percent of the growth. In the late reform period, 1985-90, technology accounts for all of the increase since the one-time effects of decollectivization have been exhausted. The study demonstrates earlier studies may have over estimated the impact of decollectivization by not fully accounting for the effects of technology.Text1 digital file (47 p.)Application/pdfenAGRICULTURAL ECONOMICSRICEHYBRID VARIETIESAGRICULTURAL PRODUCTIVITYTECHNOLOGY TRANSFERINSTITUTIONAL FRAMEWORKINNOVATION ADOPTIONMATHEMATICAL MODELSIDRC Final Report
