Abstract

For this purpose, non-parametric Malmquist index and panel data of 15 counties over 11 years were used. Results show that only Talesh and Rudsar counties achieved productivity growth during the period analysed. Moreover, three counties of Astana-Ashrafieh, Lahijan and Masal & Shandermann experienced negative changes in efficiency and technology, which resulted in a significant negative change in TFP. Among understudy counties, only Sowme’ehSara County had year-to-year increase in productivity over the period 2007 to 2016. Furthermore, the counties of Roodsar and the Sowme’ehSara had the highest and lowest fluctuations of year-to-year TFP, respectively. The average of TFP change for all counties was negative. Overall, find ings show that with the exception of the years 2011, 2014 and 2016, the major changes in TFP all occurred due to technology change.

伊朗北部蚕业生产力分析
为此,使用了11年来15个县的非参数Malmquist指数和面板数据。结果显示,在分析期间,只有Talesh县和Rudsar县实现了生产力增长。此外,阿斯塔纳-阿什拉夫、拉希詹和Masal&Shandermann三个县在效率和技术方面出现了负面变化,导致TFP出现了显著的负面变化。在替补县中,只有索梅赫萨拉县的生产力在2007年至2016年期间逐年提高。此外,Roodsar县和Sowme’ehSara县的TFP同比波动分别最高和最低。所有县的TFP变化平均值均为负值。总体而言,调查结果显示,除2011年、2014年和2016年外,TFP的主要变化都是由于技术变化。
