Chinese consumer behavior is analyzed based on rural Guangdong household survey data. For most food items, own-price elasticities estimated with an AIDS model are inelastic. Commodity substitution due to relative price changes is small, except in the case of grain. Commodities most responsive to expenditure changes are meats, poultry, fruits, sweets, and durable goods.
Based on a large-scale survey in 11 cities, this study employs probit and logit models to estimate the effects of various explanatory variables on the likelihood of biotech food acceptance in China. Analyses focus on biotech soybean oil, input-and output-trait biotech rice, and livestock products fed with biotech corn.
In this study, we estimate total factor productivity (TFP) growth as well as multilateral TFP index for 25 contiguous China provinces over the 1985-2007 period. Agricultural output growth for each province was decomposed into TFP growth and input growth, where input growth was further disaggregated into contributions from growth of labor, capital, land, and intermediate goods. Over the study period, TFP growth contributed 2.7 percentage points to output growth annually, which was slightly higher than the input growth contribution of 2.4 percentage points per annum. On average, the annual rate of productivity growth peaked during 1996-2000, at 5.1%. It slowed in 2000-2005 to a rate of 3.2% per annum and declined in the most recent years (2005)(2006)(2007) to −3.7%. Differences in productivity among regions persisted over the entire period. The tendency toward faster TFP growth in relatively well-off coastal regions may imply a widening of regional inequality.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
