To solve the overheating problem caused by the solar radiation and to keep the indoor temperature and humidity at a proper level for plants or crops, cooling technologies play vital role in greenhouse industry, and among which evaporative cooling is one of the most commonly-used methods....

Undesirable outputs (or bads) refer to the byproducts accompanied with desirable outputs (or goods) in a production process, e.g. sulfur dioxide and carbon dioxide in coal-fired power generation. The shadow price of undesirable output, which may be interpreted as the opportunity cost of abating...

This study applies Hilbert–Huang transform (HHT) and event study methods to estimate the impacts of oil price shocks on China’s macroeconomy. The HHT method is used to quantify the intensity of each shock and select target shocks for event study. Event study method is used to model the...

Energy consumption by passenger transport in Hong Kong increased rapidly in the past decades and in 2008 it accounted for 19.7% of total energy use. Improving energy efficiency has been widely regarded as an effective way for reducing energy use in the transport sector. However, the expected...

This paper proposes a parametric frontier approach to estimating economy-wide energy efficiency performance from a production efficiency point of view. It uses the Shephard energy distance function to define an energy efficiency index and adopts the stochastic frontier analysis technique to...

The potential economic damages from oil supply disruptions could be suppressed by emergency preparedness and response measures. As two of the most feasible response measures, oil import tariff and strategic petroleum reserve (SPR) could alleviate short-run oil supply and demand imbalance...

This paper uses nonparametric efficiency analysis technique to estimate the energy efficiency, potential emission reductions and marginal abatement costs of energy-related CO2 emissions in China. We employ a non-radial slacks-based data envelopment analysis (DEA) model for estimating the...

Carbon emission reduction is a long-term strategy for China to promote its economic and social development. However, emission reduction often involves a huge amount of technological investment, which could vary substantially across different provinces due to their discrepancy in economic and...

This paper establishes several efficiency models based on environmental production technology, which are capable of integrating undesirable outputs into efficiency evaluation framework. With the proposed efficiency models, we estimate the environmental efficiency, economic efficiency,...

As one of the most developed provinces in China, Jiangsu Province has been actively developing bio-energy in order to deal with its electricity supply shortage. By the end of 2010, there are 12 grid-connected straw-based power plants, but only two of them are profitable in this province. This...
