The result of the model showed urban residents＇ annual disposable income and having meals out of home play the greatest effect on the consumption of aquatic products, followed by the number of retail chains stores; family structure plays a negative effect on the consumption of aquatic products. Also, the analysis shows not only the prices of the aquatic products as well as substitutes should be considered and also the quantity of the meals consumed by residents out of home and the number of retail chains stores should be used as important associated factors in studying the change trend of aquatic products consumption, and simultaneously the effect of family structure on the consumption quantity of aquatic products should be taken seriously, so that the aquatic products consumption of Chinese residents should be further promoted and also the aquatic products market can attain a development.展开更多

In 2010, I published a paper estimating the actual income of high-income urban residents in China. Results indicated that per-capita disposable income for the wealthiest 10 percent of households in 2008 was roughly 139,000 yuan, rather than the 44,000 yuan indicated by official statistics. This suggested an aggregate gray income of 9.3 trillion yuan for China ＂s urban residents in 2008, mainly dispersed among high income groups. In 2012, Luo Chuliang et al. published a criticism paper, arguing that flawed methodology and analysis exaggerated gray income and household income gaps. This paper both responds to these criticisms and reasserts my original claim that official statistics seriously underestimate both gray income and income inequality in China.展开更多
文摘In this paper, an econometric model for the aquatic products consumption of urban residents was established, aiming at investigating the different effects of seven factors （urban residents＇ annual disposable income, annual consumption quantity of pork and poultry and related byproducts, family structure, aging level, educational background, having meals out of home, and the number of retail chains stores） on the aquatic products consumption quantity of urban residents. The result of the model showed urban residents＇ annual disposable income and having meals out of home play the greatest effect on the consumption of aquatic products, followed by the number of retail chains stores; family structure plays a negative effect on the consumption of aquatic products. Also, the analysis shows not only the prices of the aquatic products as well as substitutes should be considered and also the quantity of the meals consumed by residents out of home and the number of retail chains stores should be used as important associated factors in studying the change trend of aquatic products consumption, and simultaneously the effect of family structure on the consumption quantity of aquatic products should be taken seriously, so that the aquatic products consumption of Chinese residents should be further promoted and also the aquatic products market can attain a development.
