Abstract
Purpose
The purpose of this paper is to investigate the impacts of China’s urban segregation caused by hukou restrictions on food consumption.
Design/methodology/approach
Based on the 2007–2009 Urban Household Survey data from six China provinces conducted by the National Bureau of Statistics of China, the authors adopt a propensity score matching (PSM) method to correct for potential selection bias. A Rosenbaum bounds test is applied to evaluate the sensitivity of the PSM results to unobserved variables.
Findings
The results show that holding rural hukou (RHs) reduces the consumption of livestock products and vegetables and fruit by 8.8 and 4.8 percent, respectively. The status of hukou does not affect the consumption of grain and edible oil. Hukou impacts on food consumption are heterogeneous across income levels, with low-income and middle-income households more vulnerable to urban segregation and hukou discriminations. A stronger motivation for precautionary saving and higher welfare expenditures that not compensated by social security lead to the lower food consumption by migrant households with RHs.
Originality/value
This paper advances the research frontier by investigating the impacts of hukou system on the structure of food consumption, which accurately reflects the household welfare.

The purpose of this paper is to estimate the elasticities of demand for different dairy products, such as fresh milk, powdered milk and yoghourt, in urban China.
Abstract
Purpose
The purpose of this paper is to estimate the elasticities of demand for different dairy products, such as fresh milk, powdered milk and yoghourt, in urban China.
Design/methodology/approach
The household survey data are drawn from the annual Urban Household Survey in a Chinese province from 2007 to 2009 by applying a three-stage budgeting approach with zero consumption.
Findings
The major findings show that fluid milk is the most popular dairy product among urban households in Guangdong province, China. Demand for fresh milk is price elastic with the highest value being −1.043, indicating that price-cutting promotion programs could be carried out by dairy enterprises to increase dairy consumption. With improvements in the living standards, the demand for dairy will lead to an expansion in the size of the dairy market and will simultaneously open up new development opportunities for dairy enterprises.
Originality/value
This study adopts an Almost Ideal Demand System model inserted into inverse Mills ratios in the third stage to resolve the common problem of obtaining censored data on zero consumption observations. The research findings will provide a reference for policy makers and for enterprises in developing some price-cutting promotion programs.

Abstract
Purpose
China is not only the biggest mutton consumer, but also the top mutton importer in the world. China’s urban households are becoming the key driving force behind a surge in mutton consumption. Therefore, the purpose of this paper is to investigate the determinants of mutton demand in urban China.
Design/methodology/approach
Based on a sample of 32,910 urban households across six provinces and autonomous regions, an inverse hyperbolic sine (IHS) double-hurdle model is estimated, by maximum likelihood estimation, to reveal the determinants of mutton consumption-at-home.
Findings
The empirical results indicate that, first, household income has a positive effect on mutton consumption, and higher income households have a higher income elasticity; second, wet weather increases probability, but reduces conditional level and unconditional level; finally, minority group households consume more mutton than Han group households.
Practical implications
It is necessary for policymakers to develop a long-term outlook in relation to the increase of China’s mutton appetite and to shift from a domestic perspective to a global one and develop diversified import strategies. Furthermore, policymakers require to make a practicable emergency preplan for tackling short-term agglomeration of demand for mutton, attributed to festivals, and religious events of a minority ethnic group.
Originality/value
This is a major work based on a large sample of 32,910 urban households conducted by the National Bureau of Statistics of China. This paper uses an IHS double-hurdle model to quantify the determinants of mutton consumption; it sheds light on the climatic, regional, and ethnic characteristics of mutton consumption in urban China.

Abstract
Purpose
China has experienced a fast economic growth and shown a significant rise in income inequality in the past decades. During the same period, fluid milk consumption in urban areas has rapidly expanded. The objective of this paper is to analyze and simulate the influence of income distribution changes on fluid milk consumption of households in urban China.
Design/methodology/approach
This study applies an inverse hyperbolic sine (IHS) double-hurdle model to modeling at-home fluid milk consumption of households across different income strata based on a sample of 11,861 urban households in five provinces in China, and simulating the impact of changing income distribution, including five income growth patterns, on fluid milk consumption of total households as well as specific household groups.
Findings
The fluid milk consumption in urban China will continue to increase, with the unconditional income elasticity being 0.334 for the full sample and 0.347, 0.335 and 0.162 for the low-, middle-, and high-income groups, respectively. The simulation results show an evidence that, compared with distribution-neutral and disparity-enlarging income growth patterns, a rising income equality would lead to a more significant increase in fluid milk consumption. And the inequality-reducing income growth pattern has a larger impact on fluid milk consumption of households with seniors and no children, as well as households having no local urban household registration (hukou).
Practical implications
The government should strengthen the supply measures of fluid milk in urban areas, enlarge domestic dairy production, and diversify the sources of milk imports. It is also necessary to subsidize low-income families, especially households with seniors or households migrated from other areas without getting local urban hukou, which could simultaneously improve nutritional benefits and alleviate financial pressures.
Originality/value
A simulation considering the evolution of income distribution as well as different household groups is conducted. Widely distributed data with a large sample size and detailed demographic information are used. The problems of zero consumption and non-normal distribution are addressed by the IHS double-hurdle model.

Abstract
Purpose
In the process of economic development and urbanization, it is important to capture the outgoing rural migrant workers’ food consumption characteristics for ensuring China’s future food security. The purpose of this paper is to empirically analyze the structural characteristics in food consumption demand of outgoing rural migrant workers.
Design/methodology/approach
The food consumption of rural migrant workers is estimated using a quaids approach by the GMM estimator to reveal the determinants of the food consumption of outgoing rural migrant workers in urban China based on a sample of 876 of outgoing rural migrant workers from the 2007-2009 household survey conducted by the National Bureau of Statistics of China.
Findings
The results show that the GMM estimator is consistent compared with the SUR estimator; the conditional expenditure elasticities of grain foods, livestock products, edible oils and vegetables by outgoing rural migrant workers are0.877, 1.081, 0.787 and 0.958, respectively; the unconditional expenditure elasticities of grain foods, livestock products, edible oils and vegetables are 0.634, 0.782, 0.569 and 0.693, respectively; the conditional Marshallian own-price elasticities of grain foods, livestock products, edible oils, and vegetables are -1.004, -1.019, -0.645 and -1.021, respectively.
Practical implications
First, the differences in food consuming patterns between rural residents and outgoing rural migrant workers should be emphasized in ensuring China’s food security for the policymakers. Second, how to ensure the supply for the increase in the consumption demand of livestock products in urban areas should be a major focus of China’s food security strategy.
Originality/value
876 households of outgoing rural migrant worker from the 2007-2009 household survey conducted by the National Bureau of Statistics of China are used; compared the GMM estimator with the SUR estimator in the estimate of the QUAIDS model; it sheds light on the structural characteristics in food consumption demand of outgoing rural migrant workers.

Abstract
Purpose
The purpose of this paper is to investigate the determinants of pork consumption in urban western China and the different consumption patterns across income strata with respect to income elasticity and price elasticity of demand.
Design/methodology/approach
The double-hurdle model is fit to the household data of Sichuan and Xinjiang provinces which is from the National Bureau of Statistics urban household surveys.
Findings
The paper finds that consumers’ purchasing decisions regarding pork are related to both non-economic and economic factors. The results also indicate large differences among the determinants for decision of how much pork to buy across the three income strata. Low-income households have higher income elasticity than middle-income and high-income households. High-income and middle-income households’ level of pork consumption is more sensitive to pork price. High-income households have greater cross-price elasticity.
Originality/value
In the previous studies, the non-economic determinants of pork consumption have not been addressed, and neither does the issue of difference pork purchasing behavior across income strata for urban households in western China. So this study uses the double-hurdle model to investigate the determinants of pork consumption in urban western China.

Abstract
Purpose
The purpose of this paper is to provide the historical background of genealogical records and analyze the value of Chinese genealogical research through the study of names and genealogical resources.
Design/methodology/approach
The paper examines the historical evolution and value of Chinese genealogical records, with the focus on researching the Islamic Chinese names used by the people living in Guilin. The highlight of this paper includes the analysis and evolution of the Islamic Chinese names commonly adopted by the local people in Guilin. It concludes with the recommendations on emphasizing and making the best use of genealogical records to enhance the research value of Chinese overseas studies.
Findings
The paper covers the history of Islam and describes how the religion was introduced into China, as well as Muslims' ethnicity and identity. It also places focus on the importance of building a research collection in Asian history and Chinese genealogy.
Research limitations/implications
This research study has a strong subject focus on Chinese genealogy, Asian history, and Islamic Chinese surnames. It is a narrow field that few researchers have delved into.
Practical implications
The results of this study will assist students, researchers, and the general public in tracing the origin of their surnames and developing their interest in the social and historical value of Chinese local history and genealogies.
Social implications
The study of Chinese surnames is, by itself, a particular field for researching the social and political implications of contemporary Chinese society during the time the family members lived.
Originality/value
Very little research has been done in the area of Chinese local history and genealogy. The paper would be of value to researchers such as historians, sociologists, ethnologists and archaeologists, as well as students and anyone interested in researching a surname origin, its history and evolution.

Abstract
Purpose
Recently, the popularity of store brands has resulted in some manufacturer brands being removed from shelves. The current literature lacks empirical work on the effect of manufacturer brand erosion on consumer assortment perception and repatronage intention. Based on signalling theory, the purpose of this paper is to manufacturer brands play a signalling role and contend that manufacturer brand erosion has detrimental effects on the assortment perception due to reduced signalling efficacy.
Design/methodology/approach
A 3 (low manufacturer brand erosion vs high manufacturer brand erosion vs manufacturer brand dominance) ×2 (assortment size: small vs large) between-subject experiment was conducted.
Findings
Manufacturer brand erosion exerts a negative effect on assortment attractiveness and consumers’ repatronage intention; the greater the erosion, the larger the negative effect. These negative effects are mediated by reduced consumer perceptions of assortment quality and variety. A large (vs small) assortment size attenuates the negative effect of manufacturer brand erosion by improving perceived assortment quality.
Practical implications
To engage in strategic positioning through efficient assortment management, retailers should cooperate with brand manufacturers, instead of promoting their own private labels. Nevertheless, a large assortment dominated by store brands signals that the retailer has built a strong private brand, which in turn gains a differentiation advantage.
Originality/value
This paper is among the first to take the signalling perspective and explicitly investigate whether and how manufacturer brand erosion exerts a significant impact on assortment perception.

Abstract
Purpose
This paper aims to study the oxidation kinetics of the nanocrystalline Al ultrathin films. The influence of structure and composition evolution during thermal oxidation will be observed. The reason for the change in the oxidation activation energy on increasing the oxidation temperature will be discussed.
Design/methodology/approach
Al thin films are deposited on the silicon wafers as substrates by vacuumed thermal evaporation under the base pressure of 2 × 10−4 Pa, where the substrates are not heated. A crystalline quartz sensor is used to monitor the film thickness. The film thickness varies in the range from 30 to 100 nm. To keep the silicon substrate from oxidation during thermal oxidation of the Al film, a 50-nm gold film was deposited on the back side of silicon substrate. Isothermal oxidation studies of the Al film were carried out in air to assess the oxidation kinetics at 400-600°C.
Findings
The activation energy is positive and low for the low temperature oxidation, but it becomes apparently negative at higher temperatures. The oxide grains are nano-sized, and γ-Al2O3 crystals are formed at above 500°C. In light of the model by Davies, the grain boundary diffusion is believed to be the reason for the logarithmic oxidation rate rule. The negative activation energy at higher temperatures is apparent, which comes from the decline of diffusion paths due to the formation of the γ-Al2O3 crystals.
Originality/value
It is found that the oxidation kinetics of nanocrystalline Al thin films in air at 400-600°C follows the logarithmic law, and this logarithmic oxidation rate law is related to the grain boundary diffusion. The negative activation energies in the higher temperature range can be attributed to the formation of γ-Al2O3 crystal.
