By estimating China＇s pollution treatment productivity between 2001 and 2008 and analyzing environmental regulation intensity and the effects of the relevant factors and pollution treatment productivity using panel data, this paper discovers that （1） pollution treatment productivity contributed a significant share of about 40% to industrial environmental TFP during the investigation period; （2） environmental regulation may not necessarily cause adverse impacts on pollution treatment efficiency and productivity but demonstrates a U-shaped relationship： when the share of pollution treatment cost in industrial value-added is above the range of 3.8%-5.1%, environmental regulation is likely to promote pollution treatment productivity and thus environmental TFP Judging by the estimation result, enhancing environmental protection and expediting the development of ecological civilization are conducive to China ＂s economic transition towards an intensive, efficient, circular, and sustainable development pattern. China＇s current industrial development has the capacity to tolerate a rather demanding level of pollution treatment and management and China needs to further rely on energy conservation and the environmental production industries to promote the progress of pollution treatment technologies.展开更多

In order to provide a better understanding of how to mitigate the GHG emissions, an inventory based on different beef supply chains in the United Kingdom and in Brazil was carried out. The carbon footprint of the beef systems was calculated based on the life cycle assessment methodology. Total emissions per kg of bone-free meat were calculated at being 33.85, 33.99 and 45.17 kg of CO2e-100/kg for UK1, UK2 and Brazil farm units, respectively. Based on an average potential for carbon sequestration rate at the proportion of 12：44 for C：CO2 conversion for well managed grasslands, there is a potential sequestration of 1,980 kg of CO2/ha/year. This would potentially reduce the total emissions value for the three distinct supply chains the cases ofUKb UK2 and Brazil, respectively. as being 29.4, 28.4 and 25.4 kg C02-e 100/kg of bone-free meat for展开更多

Measuring the recreational value of world heritage sites is a key issue in the heritage tourism. This paper employs Contingent Valuation Method (CVM), which is an evaluation instrument on the basis of tourists′ attitude and preference, to measure the recreational value of Jiuzhaigou, one of the World Natural Heritage sites in China, and analyzes the biases in the survey. The results show that: 1) In 2009, Jiuzhaigou′s recreational value was 3.46×108 yuan (RMB), and the per capita Willingness to Pay (WTP) was 137.31 yuan by CVM. Compared with the results of other methods, this result is significantly low. 2) Among the factors that influence Jiuzhaigou tourists′ WTP, psychological perception factors have the greatest effect while demographic and socio-economic characteristics have a small effect on WTP. 3) The virtuality in CVM creates biases both from CVM itself and in the procedures that CVM was implemented. The former includes hypothetical bias, information bias, protest response bias, and strategic bias; and the latter includes the questionnaire design, population and sample definition, sampling and data processing. The paper analyses those biases and illustrates their potential in-fluences on the accuracy of CVM measurement. 4) Although there are various defects in CVM measurement, it is still an effective valuation method.展开更多

The first survey was conducted for the ruins of ancient ＂Diolkos＂ located in Isthmus of Corinth, Greece using a sample of 200 soldiers. The second survey was conducted for the ancient theater of Lefkada, using a sample of 100 tourists mad locals. The results have been analyzed with Logit model regression. The findings show that willingness to pay （or participate） is strongly affected by opportunity cost and awareness of the site＇s history.

The E-Bayesian estimation method of the reliability are derived for the zero-failure data from the product with Binomial distribution. Firstly, for the product reliability, the definitions of E-Bayesian estimation were given, and on the base, expressions of the E-Bayesian estimation and hierarchical Bayesian estimation of the products reliability was given. Secondly, discuss properties of the E-Bayesian estimation. Finally, the new method is applied to a real zero-failure data set, and as can be seen, it is both efficient and easy to operate.展开更多

A binomial logit model was estimated using data from a consumer survey conducted in Buenos Aires City, Argentina. Willingness to pay is explained by the consumption of organic products, health risk perceptions, concerns about production processes and also regulation issues, and label reading. The WTP calculation reveals a mean value of 21.4%/kg and a median value of 19%/kg. These results indicate that organic chicken is positively valued by consumers. In fact, it provides the nutritional and product origin information that buyers require and they consider it a safer option than conventional chicken.展开更多

In this context, the methodology of LCA （life cycle assessment） is certainly one of the most innovative methods in the field of environmental protection as it allows evaluating the environmental burdens associated with a product, process or activity by identifying and quantifying material and energy consumption and environmental emissions. The objectives focus on finding the main impacts of the wine life cycle, as well as identifying crucial activities/stages in the wine production which establish the largest impacts. This paper＇s objective is to expose the advantages resulting from the use of the LCA method in the wine production sector, with a specific application to wine production in the Tuscany region.展开更多
