China as a Potential Market for U.S. Pork Exports

This study provides details of emerging opportunities for U.S. pork exporters following the U.S.–China WTO Accession Agreement. The Agreement will enable the United States to gain unprecedented access to the Chinese pork market. The United States enjoys comparative advantages in producing hogs at lower cost, higher quality, and greater efficiency. Moreover, Chinese preference for pork is highly complementary to that of U.S. consumers. Therefore, U.S. pork exporters are expected to target primarily the Chinese variety meats market. Although China is expected to remain a surplus pork production nation, demographic shifts could provide additional opportunities for U.S. pork exporters to increase sales of more premium cuts for urban consumers in China.     

我国水产学科改革面临的新形势与急需解决的问题

我国水产学科改革正面临着新的形势:经济全球化和渔业国际化步伐加快,水产科研和教育的国际化发展,水产组织机构的多元化和水产市场的复杂化,“科教兴国”、“人才强国”和“科教兴渔”战略的实施以及“质量、效益型”渔业对水产人才提出了更高的要求。针对这些新形势,我国水产学科建设急需解决下列问题:在水产科研体制改革方面,水产业与人及自然和谐方面的总体能力羸弱;水产业吸纳现代化科技成果滞后,且普及应用能力弱;基础性研究严重滞后使得其不能满足行业发展中解决新问题的需要;水产行业软科学研究的薄弱已经严重制约了管理决策的科学性。在水产高等教育教学改革方面,也存在一些突出问题。     

Demand for wild edible mushrooms. The case of Lactarius deliciosus in Barcelona (Spain)

Wild edible mushroom demand has increased substantially in OECD countries in the last few years. Nevertheless, few studies have been published in recent years on these markets. The main objective of this paper is to characterise the saffron milk cap (Lactarius deliciosus Fr.) demand in Spain. Data sources in this study come from main Central Markets in Spain. Using econometric methods, we have found that the consequence of an increase in the price of the saffron milk cap has a negative effect on demand. However, changes in the percentage of persons born in Catalonia every year exercise a positive effect, and price increases in the Madrid market could also induce an increase in the Lactarius deliciosus demand in the Barcelona Central Market. The consequences of chanterelle imports on the Catalan demand for the saffron milk cap appear to be negative. Finally, results indicate that the saffron milk cap and oyster mushroom behave as complementary goods and, therefore, consumption of one of these mushrooms reinforces the other's consumption.

Toward a consumer economy in China: implications of changing wage policies for U.S. cotton exports

The effect of a Chinese minimum wage increase on China's textile market as well as on the world cotton market is evaluated. Based on a Nonlinear Quadratic Almost Ideal Demand System (NQAIDS) model of China's textile demand, the results suggest that the income elasticity for textiles is around 0.6 in China, and that apparel is less price responsive than home textiles and other textile products. Simulation results suggest that a minimum wage increase would raise Chinese domestic textile consumption and lower Chinese textile exports. Most of the decline in textile exports by China is offset by expansion in other countries’ domestic textile production and results in a slight increase in world cotton mill utilization and higher clothing prices.

新一轮国际粮食价格上涨：原因及对中国市场的影响

[目的]随着中国粮食进口不断增加,国内外市场联系越来越紧密。2020年下半年以来,国际市场粮食价格快速上涨,对国内粮食市场产生一定影响,分析国际市场价格上涨的原因和影响对确保国内粮食供应稳定、保障国家粮食安全具有重要意义。[方法]文章分析了2019年以来小麦、大米、玉米、大豆4种粮食产品的国内外价格走势,从供需状况、贸易政策、气候变化等因素分析国际市场价格波动的原因,并探讨了国际价格对国内价格的影响。[结果]当前全球主要粮食品种供应充足,库存仍处于较高水平,此轮国际粮食价格上涨主要是受到美国等发达国家宽松的货币政策以及疫情后全球消费逐步回暖的影响;但国际市场价格上涨对中国市场的影响总体有限,国内小麦、大米、玉米价格上涨的主因是国内消费回暖和生猪产能恢复带动的饲用需求快速增长,油用大豆受国际市场的影响较大。[结论]为稳定国内粮食市场,避免国际市场的冲击,中国要进一步提升粮食综合生产能力,强化科技支撑,加强粮食储备管理,健全政策支持体系,并引导居民建立科学的消费观念。     

The evolution of foreign wine demand in China

We estimate source‐differentiated wine demand in China using the absolute price version of the Rotterdam demand system. Within the last decade, China has gone from obscurity to an important participant in global wine trade. The continual growth of Chinese wine imports suggests that a one‐time structural shift approach may not fully capture how consumption patterns or demand preferences have changed over time. Thus, a rolling or moving regression procedure is used to account for continual adjustments in import demand patterns and to evaluate overall parameter instability. Our results confirm that Chinese consumers hold French wine in high regard and that French wine demand has consistently increased over the last decade, more than any other exporting source. Consumers in China have gone from allocating about 1/3 to over 1/2 of every dollar to French wine and the expenditure elasticity for French wine mostly increased while the market was expanding. Although Australian wine has a very solid standing in the Chinese market, results suggest that its market share will likely remain unchanged. Marginal budget share and expenditure elasticity estimates indicate that Australia will continue to account for about 20 per cent of the foreign wine market in China.     

Demand for milk quantity and safety in urban China: evidence from Beijing and Harbin

Urban households account for most of the milk consumption in China, but their consumption is hampered by safety concerns. Using survey data collected in Beijing and Harbin in 2010, this paper simultaneously analyses urban households' milk consumption using a multiple linear model and their willingness‐to‐pay for milk safety using an ordered choice model. The results of this study show that as income increases, urban households consume more milk and are willing to pay a higher premium for milk safety. Modern food marketing channels play a positive role in stimulating milk consumption and building consumers' confidence in milk safety. The growth in the elderly population influences milk consumption positively, but their demand for milk safety is negatively affected by higher price. The combined analysis of households' demand for milk quantity and safety may be useful to the Chinese government in promoting the development of the domestic milk industry and to dairy firms in exploring the milk market in China.     

Consumption Trends of Edible Mushrooms in Developing Countries

Abstract

Mushrooms are an important commodity worldwide. However, a thorough understanding of consumption trends is not yet available. In developing countries, the importance of edible mushrooms within consumer preferences and perceptions has not been studied. We carried out a study (2000-2003) to understand the patterns of mushroom consumption in central Mexico, where most wild/cultivated mushrooms are produced and/or marketed. About one-half (49.4%) of urban consumers bought mushrooms, independently of their social level [fresh or canned: white button mushroom (Agaricus), oyster mushroom (Pleurotus), shiitake (Lentinula). Preferences and perceptions from Mexican consumers depended on the social level. Mushroom prices were considered very or moderately expensive. Mushrooms were markedly more expensive than foods widely consumed. The variation of mushroom prices was a major factor influencing consumption. Basic data to carry out further marketing research are discussed, as well as an integral strategy considering social levels and regions to increase mushroom consumption.
