چکیده مقاله:
In this paper, production function decomposition analysis is used to decompose the difference in the rice output between new and old rice production technologies (application of High-yield and Local varietes) into technical change and change in quantities of inputs. It is based on cross-section input-output data collected at one time (2009-2010) from sample farmers included 100 observations ,Case study Mazandaran province-Iran. Results show that there is structural break in production relation with the introduction of high-yield varietes in rice production . Production function decomposition analysis was also used to decompose the difference between new and old rice production technologies .The results show that total growth in rice yield by shifting to new rice production technology was about 126 per cent. secondly, the countribution of increased level of inputs was 48 percent and the total value of inputs saved (VIS) on the sample farms with new technology was estimated to be 63622 ten thousand Rials. The estimated additional quantity of rice output with new technology using old technology level of inputs was 174.8 tones on the sample farms. .
