Nearly one-third of all smokers in the world or over 300 million smokers reside in China, consuming an estimated 2.3 trillion cigarettes every year (1). According to the China Global Adult Tobacco Survey (GATS) in 2018, the prevalence of current smoking among Chinese aged 15 or older was 2.1% in women and 50.5% in men (2). The high prevalence of smoking in Chinese men might be due to the persistent normalization of smoking within Chinese culture, where cigarettes were commonly used as a form of sharing or gift-giving for interpersonal relationships and magnanimity during festivals and weddings, and as business favors (3).
Branding of cigarettes may play a unique role in affecting the smoking behaviors of Chinese smokers due to the abundance of Chinese cigarette brands and their varieties. This was largely due to a brand consolidation strategy by the China National Tobacco Corporation (CNTC), which has a monopoly over China’s cigarette market, accounting for 98% of domestic sales (4). From 1990 to 2013, the CNTC reduced the 2,000 cigarette brands to 90 brands (4). The CNTC includes several major local/regional subsidiaries that manufacture flagship cigarette brands. These local brands (LB) often are packaged and advertised through the use of symbols and pictures that represent regions and local landmarks. Smokers may use cigarette brands as symbols of their home regions, suggesting that they prefer their home region’s cigarettes over others (5). An example of this local branding can be seen in Figure 1, where the CNTC local subsidiary, China Tobacco Hubei Industrial Co. Ltd, uses the Yellow Crane Tower (Huanghelou) as its brand name, with its photo on the packaging, thus linking its brand to this famous landmark, which has been the object of several famous poems (6).
Cigarette brands have often been linked to symbols of China — both national and local, and the presence of these symbols on the packs of many cigarette brands, such as the image of the Forbidden City on packs of Chunghwa cigarettes (whose brand name is literally the name of the country), has been cited by China as a reason for not implementing graphic warnings as recommended by Article 11 of the World Health Organizaiton (WHO) Framework Convention on Tobacco Control (FCTC) — that graphic images of disease would not be appropriate when appearing next to these national symbols.
Thus, LBs may affect smokers because of the positive branding strategies that reflect their local origins. But in addition, under the China tobacco taxation system where most tobacco taxes are collected at the producer and wholesale levels and shared with local governments, there is an incentive that the CNTC pushes for the production and sale of local brands locally so that tobacco producing provincial-level administrative divisions (PLADs) and lower-level governments can count on the tobacco tax revenues for their expenditures, a phenomenon called “tobacco finance” in China.
To our knowledge, this study is the first to conduct an empirical analysis of local brands in China. The objective of this study was to assess the percentage of LB smoking among adult smokers in a diversity of cities in China and to identify factors associated with LB smoking including demographic characteristics and patterns of smoking such as cigarettes per day.
This project analyzed data from the Wave 5 International Tobacco Control (ITC) China Survey that was conducted between November 2013 and July 2015 (9-10). The ITC China Survey is a longitudinal cohort survey of smoking behavior and knowledge, beliefs, opinions, and attitudes about cigarette smoking and tobacco use among adults aged 18 and older in China. The Wave 5 Survey was conducted in 10 locations, including urban residents in 5 large cities (Beijing, Guangzhou, Kunming, Shanghai, and Shenyang) and residents in 5 rural areas (Changzhi, Huzhou, Tongren, Yichun, and Xining). The 10 locations were selected based on size, geographical representations, and levels of economic development (11–12).
Kunming, Guangzhou, Shanghai, Huzhou, Tongren, and Beijing have LBs and local cigarette manufacturing facilities; all of these locations were therefore labeled as local ventures (LVs) in this study excluding Beijing, which entered into a venture with a non-local company (Shanghai Tobacco Group) and a local cigarette factory and was labelled a non-local venture (NLV). Changzhi does not have LBs but has manufacturing facilities in its province and was labeled as NLV; Shenyang and Yichun have few LBs produced by subsidiaries of non-local parent companies and local cigarette factories and were also labelled NLVs. Xining has neither LBs nor local manufacturing facilities and was excluded. A multistage cluster sampling method was used to create a representative sample of adults aged 18 and older; more detail is provided in the Supplementary Material. More information on sampling methodology and sampling weights can be found in the ITC technical documentation (10).
The outcome variable in this study was LB smoking status, which was determined by the following question: “In the last 30 days, what brand of cigarettes did you smoke more than any other?” (12), and the information regarding provincial subsidiary manufacturer for each brand collected in the ITC China Survey. The answer to this question was defined as the smoker’s primary brand. If the province (or PLAD) of manufacture for a smoker’s primary brand was the smoker’s province of residence, this smoker was defined as an LB smoker; otherwise, they were defined as a non-local-brand (NLB) smoker. For example, if a smoker from Kunming City of Yunnan Province listed Red Pagoda Hill (Hong Ta Shan) as their primary brand and the Yunnan Tobacco Company is the provincial subsidiary manufacturer, then this smoker was categorized as an LB smoker. Those who refused to answer or reported unknown status were coded as missing and excluded from our sample.
The covariates considered in this study included sociodemographic characteristics, an indicator for rural/urban area type, an indicator for NLVs/LVs, city of residence, and smoking behaviors. Sociodemographic characteristics included sex (female and male), age groups (18–24, 25–39, 40–54, and 55+), ethnicity (non-Han and Han), monthly household income [high income (≥3,000 CNY, 482 USD of 2015 exchange rate (13)], medium income (1,000–2,999 CNY, 161–482 USD), low income (<1,000 CNY, 160 USD), and unknown, education high (at least some college), medium (senior high school), and low (less than senior high school), and marital status (married or living with a partner, divorced or separated, widowed, and single). Participants who did not report income (995 of 6,642) were not excluded but were classified in the “unknown” group because data on income might not be missing at random. Smoking behaviors included smoking frequency (daily and non-daily), smoking intensity (heavy: ≥10 cigarettes per day; and light: 0–10 cigarettes per day), and time to smoke the first cigarette after waking (0–30 min and ≥30 min).
A total of 9,880 adults participated in the survey, including 7,583 current smokers, 234 former smokers, and 2,063 never smokers. This study focused on current smokers, defined as those who have smoked at least 100 cigarettes in their lifetime and currently smoking cigarettes at least once a week (11). After excluding those with missing data on LB smoking status, the sample size for analyzing the percentage of the LB smoking included 6,642 current smokers. For the multiple logistic regression described below, participants that had missing values for age, ethnicity, education, marital status, and smoking intensity were excluded and resulted in a final study sample of 6,419 participants.
The weighted percentage of LB smoking was estimated for all current smokers and for subgroups stratified by each covariate using sampling weights provided by the Wave 5 ITC China Survey, further details can be found in the Technical Report (10). The bivariate analysis chi-square test was conducted to determine if there was any statistically significant difference in the percentage of LB smoking across all subgroups of each covariate. A multiple logistic regression model was used to estimate the propensity of LB smoking among current smokers, adjusting for all the covariates except employment status and city of residence because employment status was highly correlated with age, and city of residence was highly correlated with the rural/urban area type. The model used the sampling weights. The association between each covariate and LB smoking was determined by an estimated adjusted odds ratio (AOR). All analyses were conducted in R (version 4.1.1., R Core Team, Vienna, Austria). Estimates were considered to be statistically significant if the two-tailed p-value was <0.05.
Table 1 shows that among 6,642 current smokers, most participants were men (96.2%), aged 40–54 (41.9%), of Han ethnicity (87.4%), had high income (59.7%), had medium education (62.7%), were married or living with a partner (86.6%), resided in an urban area (51.4%), resided in areas with a LV (56.5%), were daily (92.4%) or heavy smokers (60.0%), and smoked their first cigarette 0–30 min after waking (58.2%).

Table 1. Distribution of the study sample and the percentage of local brand smoking by sociodemographic characteristics and smoking behaviors among current smokers in Wave 5 of the International Tobacco Control China Survey (n=6,642).
Table 1 also shows that the percentage of LB smoking was 47.6% among all current smokers. The bivariate analysis results indicated that the percentage of LB smoking was significantly different by sex (34.8% for female and 48.1% for male), age, ethnicity (75.2% for non-Han ethnicity and 43.7% for Han), income, education, marital status, area type (44.8% for rural area and 50.4% for urban area), NLVs (10.5%) vs. LVs (76.2%), smoking frequency (48.3% for daily smokers and 40.1% for non-daily smokers), and smoking intensity (49.9% for heavy smokers and 44.4% for light smokers), but was not statistically different by time to smoke the first cigarette after waking. As shown in Figure 2, among the 9 locations, the percentage of LB smoking was high for areas with LVs (Kunming at 96.20% and Tongren at 84.85%) and low for areas with NLVs (Changzhi at 0.00%). The percentage of LB smoking in Shenyang was 2.7%, which was due to a limitation in defining LB smoking — these LB smokers smoked Ren Min Da Hui Tang that are produced locally by an NLV.
