Using the Engle-Granger (EG) test and considering the possibility of structural changes, the impact of external economic shocks on the long-run equilibrium relationship between economic growth and consumption in China was analyzed. Analysis results show that without considering structural changes, the EG test cannot detect cointegration in the series subjected to structural changes; in considering structural changes, cointegration is successfully detected by specifying the dummy variable. In addition, the error correction models were constructed in different periods. This study verifies the existence of a long-run equilibrium relationship between economic growth and consumption in China, and this relationship has significantly changed in 1989 and 1997, respectively.展开更多

The results showed that urban consumption growth made the most contribution to aggregate consumption growth, followed by urban-rural migration caused consumption. The role of rural consumption growth kept stable, but consumption caused by population growth was decreasing. Therefore, China consumption growth mainly relies on urban consumption expenditure and urban-rural migration.展开更多

For China,promoting the decoupling between economic growth and carbon emissions as soon as possible is not only the core task of achieving the medium-and long-term goals and strategies to address climate change, but also the inevitable requirement for ensuring the sustainable development of economy and society. Based on the analysis of the historical trends of the economy and social development, as well as society, energy consumption, and key end-use sectors in China, this paper studies the deep carbon emission reduction potential of carbon emission of in energy, industry, building, and transportation and other sectors with "bottom-up" modeling analysis and proposes a medium-and long-term deep decarbonization pathway based on key technologies' mitigation potentials for China. It is found that under deep decarbonization pathway, China will successfully realize the goals set in China's Intended Nationally Determined Contributions of achieving carbon emissions peak around 2030 and lowering carbon dioxide emissions per unit of gross domestic product(GDP) by 60-65% from the 2005 level.From 2030 onward, the development of nonfossil energy will further accelerates, and the share of nonfossil energies in primary energy will amounts to about 44% by 2050. Combined with the acceleration of low-carbon transformation in end-use sectors including industry, building, and transportation, the carbon dioxide emissions in 2050 will fall to the level before 2005, and the carbon dioxide emissions per unit of GDP will decreases by more than 90% from the 2005 level. To ensure the realization of the deep decarbonization pathway, this paper puts forward policy recommendations from four perspectives, including intensifying the total carbon dioxide emissions cap and strengthening the related institutional systems and regulations, improving the incentive policies for industrial lowcarbon development, enhancing the role of the market mechanism, and advocating low-carbon life and consumption patterns.展开更多

It can motivate customers to change their consumption patterns according to the dynamic(time-varying) electricity price, which is considered to be the most cost-effective and reliable solution for smoothing the demand curve. However, many existing schemes, based on users' demand request in each period, require users to consume their requested electricity exactly, which sometimes causes inconvenience and losses to the utility, because customers cannot always be able to consume the accurate electricity demand due to various personal reasons. In this paper, we tackle this problem in a novel approach. Instead of charging after consumption, we adopt the prepayment mechanism to implement power request. Furthermore, we propose a trading market running by the control center to cope with the users' dynamic demand. It is noteworthy that both users' original demand and trading records are protected against potential adversaries including the curious control center. Through the numerical simulation, we demonstrate that our scheme is highly efficient in both computation and communication.展开更多

In order to accomplish that, 225 Nile tilapia juveniles (average initial weight 5.0 g ± 0.5 g) were distributed in five tanks, each containing a group of 45 fish. One group of fish were fed exclusively with a high protein mix (HPM; δ^13C = -22.62‰), the second one fed only with a low protein mix (LPM; δ^13C = -14.34‰). The other groups had free access to both mixes (free choice system). The fish from all tanks were fed four times a day. Muscle, liver and blood samples were collected at each five days (from 2 fish/tank/collection) for 86 days, except for the fish fed with LPM (fed for a 120 days period). The samples were analyzed in a mass spectrometer and proportions of the mixes consumed were estimated through its carbon isotope enrichment (δ^13C). Energy intake slightly decreased after the 50th day and protein consumption increased after the same period. However, consumption did not present a clear pattern in relation to the individual weight, i.e., protein consumption patterns are mainly related to the age of the individuals and it is not clear if it is also correlated to their weight. Additionally, this technique allowed the observation of differences regarding consumption among the individuals from the experimental group.展开更多

Due to the high demand of 2.66 million metric tons per annum for fish, Nigeria imported 740,000 tons in 2007 to supplement the domestic production of 615,507 tons. A study was conducted in Ibadan Metropolis of Oyo State (a land locked state) to determine the consumer preference and pattern of marine fish species consumed. Stratified sampling method was used to select respondents from three income earning levels of the five local government areas in Ibadan Metropolis. Questionnaires were administered to 51 marine fish retailers and 151 households. Data collected was analyzed using descriptive statistics and Tobit regression model. Marine fish sellers ranked horse mackerel (Scomberjaponicus) first and croaker (Pseudotholithus species) the least because it is more priced. Only 10.6% and 13.2% of the households preferred express (Brevortia species) and croaker respectively, but Hake (Gadus gadus) was the least preferred (41.7%). The household consumed varying proportions of fish species every week. The regression result (R2 = 0.65) showed that married household heads with large household size having lower years/level of education, younger in age and earning lower income are likely to consume more of marine frozen fish species (P 〈 0.01) than others.展开更多

The specific objectives of the paper are to: examine the household preference and consumption level of local and imported rice, examine price variation between local and imported rice and identify the major problems confronting marketers of local and imported rice. Data were collected from 100 randomly chosen households with the aid of structured questionnaire. Data collected were analyzed with the use of descriptive statistics such as frequency, percentages, chi-square, t-test and regression analysis. The paper revealed among others that majority of the respondents prefer to consume local rice to imported rice because of its more palatability, health benefits, readily availability and relatively cheap price. The average price per kilogramme of local rice is 200 Naira compared to that of imported rice which is 300 Naira. The difference in price is as a result of exchange rate and costs associated with smuggling of imported rice across the border of Nigeria from neighbouring countries. Nonetheless, the quality of local rice is still very low when compared to imported rice in terms of degree of impurities such as stone and shafts and the level of polishing.展开更多

The aim of this paper is to analyse the environmental and well being impacts of consumption and production systems in Baltic Sea Region and draw conclusions about transferring of best practises in Latvia. This study is based on indicator analyses, focusing on data of environmental impacts from consumption and production in the region, and analyses drivers behind these impacts. The paper concludes two trends--Scandinavian countries and Germany which have more advanced economies demonstrate much higher ecoefficiency and environmental management practices compared to the new EU member states. The example of the Baltic Sea region shows that high income levels and a stable development path in the old EU member states provide grounds for technology advancement to reduce the environmental impact of production. However Baltic States and Poland on average demonstrate much more sustainable consumption patterns. But the trends in these countries are negative--they try to copy lifestyles and consumption patterns of more advanced economies with higher ecological footprint. Challenge for Latvia is to improve its ecoefficiency but at the same time develop more sustainable consumption patterns.展开更多

They imply large investments the costs of which companies and governments, in charge of elites are not always willing to endure. Changes in elites have a direct impact on public policy and environmental governance of societies. Are the new elites willing to change traditional patterns of energy consumption if the change could threaten investment and economic growth3 Based on empirical research this paper analyzes the role of elites in a developing Latin American country (the Chilean case) in decisions adopted about the explanations of climate change and specially on the set of measures for adaptation and/or mitigation, focusing on the energy sector of the economy, one of the key sectors directly implied with the possibilities of reducing greenhouse gases emissions.展开更多

Marketing is usually described as a set of tools used by businesses to promote the exchange of goods and services produced in order to fully meet the demand of the community of the territory in which they operate. Therefore, to apply marketing to the territory, one needs to identify a set of rules for programming, evaluation, and promotion, in order to attract producers and consumers to an area, in which there are both tangible and intangible factors. The ability to create a development process is not only related to the possession of these factors, but also and above all to the ability to make them cohesive so that the area as a whole has more value than its individual components. In this paper, the authors show that it is not so much the actions carried out by local political institutions, but those of IKEA~ itself have contributed to the improvement of the area around Bari, where it has chosen to open a store.展开更多

Data derives from a food consumption survey on organic and non-organic consumers conducted in Buenos Aires City, Argentina, in April 2005.The Lancaster model (1966) provided the theoretical basis. The results yielded by the estimated logistic model suggest that consumers with higher educational level, who eat healthy food, and consider food control organisms as "inefficient" are more likely to buy organic products. A high percentage of consumers read and trust label information in Argentina. This has interesting policy implications to promote differentiated and high value products, and to reduce information asymmetries.展开更多
