The growth of China's industry has been seriously depending on energy and environment. This paper attempts to apply the directional distance function and the Luenberger productivity index to measure the environmental efficiency, environmental total factor productivity, and its components at the level of subindustry in China over the period from 1999 to 2009 while considering energy consumption ...

in this study, yield-water and profit function was used to obtain water demand function in agriculture sector. the results showed that the ratio of actual to potential evapotranspiration had positive, significant effecton the ratio of actual to potential yield for wheat and barley. also, square ratio of actual to potential evapotranspiration had negative, significant relationship. after estimat...

Pakistan is one of the world’s leading producers, exporters, and consumers rice. This study analyzes technical efficiency rice growing farmers in Swat district Khyber Pakhtunkhwa province Pakistan. A three-stage sampling procedure was used to interview 204 growers through a well-structured pretested schedule. The maximum likelihood function results showed that chemicals, urea, diammonium phosph...

Pesisir Selatan Regency the second producer of gambier Gambier farming still facing various obstacles, one which technical constraints, namely low productivity gambir period 2016 to 2020. This study aims analyze efficiency identify sources inefficiency Regency. The survey was ...

Growing social concerns over the environmental externalities associated with business activities are pushing firms to identify activities that create economic value with less environmental impact and to become more eco-efficient. Over the past two decades, researchers have increasingly used frontier efficiency models to evaluate productive efficiency in the presence of undesirable outputs, such...

in this research the activity of 75 producers, 55 wholesalers and 55 retailers, citrus market of jahrom county was investigated. the results indicated that margin of wholesale, retail and total margin of citrus in this county was 1461.1, 1480.3, and 2941.4 rs respectively. share of producer from marginal price was estimated to be 57.9 percent and share of wholesaler was more than retailer. in t...

Upper bound of efficiency loss is a valuable issue for transport network design and planning. This paper initially explores it in a taxed stochastic traffic network whose equilibrium flow pattern is deduced by a cross-nested Logit (CNL) flow assignment model, and a centrally controlling Stackelberg strategy. With the assumptions of separability, nondecreasingness, and convexity of the link time...

A stochastic frontier production function is defined for panel data on firms, in which the non-negative technical inetGciency effects are assumed to be a function of firm-specific variables and time. The inefficiency effects are assumed to be independently distributed as truncations of normal distributions with constant variance, but with means which are a linear function of observable variable...
