The real income and consumption of an Urban Chinese family
估算了1989年一个代表性中国城市高收入家庭在加拿大购买同等商品和服务的成本，发现购买力平价成本与按汇率换算的成本之比高达10.5，并探讨了原因。
This study estimates for 1989 the cost in Canada of the products and services consumed by a representative urban Chinese family in the second highest income quintile. The ratio of this figure, called the purchasing power parity cost, to the figure obtained by converting the yuan cost of the consumption to dollars at the exchange rate was 10.5. This ratio is very much higher than the ratio for other underdeveloped countries, and reasons for the difference are examined.
