Differential responsiveness to cigarette price by education and income among adult urban Chinese smokers: Findings from the ITC China Survey
Abstract
Background
Few studies have examined the impact of tobacco tax and price policies in China. In addition, very little is known about the differential responses to tax and price increases based on socioeconomic status in China.
Objective
To estimate the conditional cigarette consumption price elasticity among adult urban smokers in China and to examine the differential responses to cigarette price increases among groups with different income and/or educational levels.
Methods
Multivariate analyses employing the general estimating equations method were conducted using the first three waves of the International Tobacco Control (ITC) China Survey. Analyses based on subsample by education and income were conducted.
Findings
Conditional cigarette demand price elasticity ranges from −0.12 to −0.14. No differential responses to cigarette price increase were found across education levels. The price elasticity estimates do not differ between high-income smokers and medium-income smokers. Cigarette consumption among low-income smokers did not decrease after a price increase, at least among those who continued to smoke.
Conclusions
Relative to other low-income and middleincome countries, cigarette consumption among Chinese adult smokers is not very sensitive to changes in cigarette prices. The total impact of cigarette price increase would be larger if its impact on smoking initiation and cessation, as well as the price-reducing behaviours such as brand switching and trading down, were taken into account.
