Energy consumption and total factor productivity growth in Iranian agriculture

economic optimization and energy consumption in tray dryers

دراین پروژه به بررسی مدل سازی خشک کردن مواد غذایی با استفاده از هوای خشک در خشک کن آزمایشگاهی نوع سینی دار پرداخته شده است. برای آنالیز انتقال رطوبت در طی خشک شدن به طریق جابجایی، یک مدل لایه نازک برای انتقال رطوبت، مبتنی بر معادله نفوذ فیک در نظر گفته شده است که شامل انتقال همزمان جرم و انرژی بین فاز جامد و گاز می باشد. پروفایل دما و رطوبت برای سه نوع ماده غذایی شامل سیب زمینی، سیب و موز در طی...

Total-factor energy productivity growth of regions in Japan

This article computes the energy productivity changes of regions in Japan using total-factor frameworks based on data envelopment analysis (DEA). Since the traditional DEA-Malmquist index cannot analyze changes in single-factor productivity changes under the total-factor framework, we apply a new index proposed by Hu and Chang [2009. Total-factor energy productivity growth of regions in China. ...

Trends in Total Factor Productivity in Pakistan Agriculture Sector

Total factor productivity (TFP) has emerged as an important source of agriculture growth. However, this area remained neglected by researchers as well as policy makers in Pakistan. The studies which have estimated agriculture TFP growth in Pakistan are very few and they have tended to overstate it by ignoring the variation in capacity utilization, hours worked and improvement in labour producti...

Total Factor Productivity and Sources of Long- Term Growth in Indian Agriculture

This paper assesses total factor productivity (TFP) growth in India, examines the sources of productivity growth, including public and private investment, and estimates the rates of return to public investments in agriculture. The results show that significant TFP growth in the Indian crops sector was produced by investments -primarily in research -but also in extension, markets, and irrigation...
