The over‐saturated dietary supplement (DS) market in developed countries such as the US spurs the need for foreign market expansion, and the Chinese market provides a great potential for the foreign soy‐based DS industry. This study examined Chinese consumers' intention to use imported (US‐made US‐brand) soy‐based DS based on the Theory of Planned Behavior (TPB). Two alternative models were also examined in which Chinese dietary culture variables, including soyfoods favourability and dining‐out sociability, as well as their interactions with attitudes, were integrated into the TPB model. A cross‐sectional, self‐administered survey was conducted with a sample of 215 subjects (137 females; 78 males) in Shanghai, China. The TPB variables attitude, subjective norm, perceived behaviour control and behavioural intention, as well as the Chinese dietary culture variables: soyfoods favourability and dine‐out sociability were measured. Multiple linear regressions were used to analyze the three models. The statistical results indicated that all three models were statistically significant to predict intention (Model 1: R2 = 0.473, P < 0.001; Model 2: R2 = 0.505, P < 0.001; Model 3: R2 = 0.525, P < 0.001). The results also showed that attitude, perceived behavioural control, and dine‐out sociability were significant (positive) determinants of intention. Soyfoods favourability acted a significant (negative) moderator of the relationship between attitude and intention. Subjective norm had no significant impact on intention. In conclusion, the TPB model was useful to predict Chinese consumers' intention to use imported soy‐based DS, but not all the TPB components weighed significantly in exploring DS consumption in China. The selected Chinese dietary culture variables were much more important predictors than subjective norm. This study makes a significant contribution in the application of the TPB model and in market strategy development for imported dietary supplements in China.  相似文献

Argentina plays an important role in the global soy market as one of the world's leading exporters of soy products. In an effort to shift its agricultural sector's focus to value‐added exports and to raise revenue, Argentina's government has maintained a regime of differential export taxes on soy products. In addition to soy products, Argentina is a major producer, consumer and exporter of beef. However, over the last decade it has relinquished much of its world market share as its beef exports have fallen because the government has periodically imposed a ban on exports of beef along with maintaining an export tax. As the soy and livestock sectors are inextricably linked, owing to both industries’ intensive land use and the utilisation of soymeal as a feed supplement for cattle, trade policies in one sector have pronounced cross‐sectoral impacts. This study develops a theoretical model of these different sectors and trade policies, incorporating the dynamic decisions of cattle stock management. The model is calibrated to real‐world data on the Argentinean economy, and the impacts of trade liberalisation are quantified. Key results show modelling the various intersectoral linkages and the dynamic implications of cattle stock is essential for obtaining accurate estimates.  相似文献

This paper analyses the politics of agrarian change in Bolivia in the context of the development and expansion of the soy complex in Santa Cruz. It attempts to contribute to a better understanding of the nature and role of the state in relation to agrarian change through what is referred to here as the state–society–capital nexus. From an “agrarian” to a “productive” revolution in the countryside, this paper situates the rise of the Movement Toward Socialism (Movimiento al Socialismo, MAS) to state power and its ability to maintain control over the state apparatus by balancing both accumulation and legitimation interests through its neo‐extractivist development strategy. As extractivist rents fall with the commodities bust and smallholders' exclusion becomes more apparent, the MAS' overextension in facilitating capital accumulation is beginning to show signs of a legitimacy crisis. The politics of agrarian change remain as contested as the dynamics within the state–society–capital nexus.  相似文献

Interest in soy foods has increased with consumer awareness of its health benefits, especially with soy‐related ingredients being utilized as one of the major sources of high‐protein fortification. The aim of the present study was to assess South African (SA) consumers' opinion of soy and soy products through different statements on consumption, taste, protein value and healthiness. The respondents (n = 3001) for this randomized cross‐sectional study were randomly selected from metropolitan and rural areas in South Africa. Trained fieldworkers administered questionnaires by conducting face‐to‐face interviews. Fourteen statements from four sections of the questionnaire (consisting of 17 food‐related topics in total), probing information on consumers' opinion on soy and soy products, were used. Data on 81% of the respondents (n = 2437), who had heard of soy before, were used for statistical analyses. The data were weighted to be representative of the total SA population based on gender, age and race. No practically significant differences among metropolitan and rural respondents' opinion, gender or age variables regarding any statement were found. A practically significant higher percentage (>60%) of respondents in the total population and within all race groups were positive about soy and agreed that soy is a good source of protein, has many health benefits, associated soy with meat substitutes, were aware of a number of meat substitutes and agreed that soy can replace meat in their diet. Medium to large practically significant differences were found between racial groups regarding certain statements. More Blacks and Indians (76% and 68% respectively) than Whites (25%) use soy. Almost two‐thirds of Indians (65%) and Blacks (64%) eat or drink soy products, compared with only 22% for Whites, indicating that the potential target market for soy products should be chosen accordingly. Higher percentages of Blacks than Whites also indicated that they liked the taste of soy, would use more soy if it was readily available and if a bigger product range existed and would replace cow's milk with soy milk, confirming that Blacks are more positive about soy and would use even more soy if a bigger range of soy products were available. The findings from the current study indicated that more than 70% of SA consumers believe that soy has many health benefits and more than 60% already use soy. Insight gained from this first study of its kind in SA provided valuable information to developers and marketers, and signified that consumer segmentation should be taken into consideration to focus on developing more acceptable soy products that appeal to these consumer segments that are more positive towards the taste of soy and might consume soy regularly. Within the discipline of Consumer Science, efforts to inform consumers about the advantages of soy in terms of its health benefits, and to support it in terms of a greater availability of more acceptable soy products at reasonable prices, would support the ideal of informed, responsible buying decisions across all socio‐economic groups.  相似文献
