消费者对茶油价值认知不足产生的信息不对称使得茶油市场失灵,潜在的市场需求无法转变为实际的市场需求。调查统计表明,消费者对茶油具有较好的知名度,但却只有较低的价值认知度。影响消费者对茶油价值认知的主要因素包括消费者的性别、学历、收入水平和对健康的关注程度。对茶油价值的认知不再依赖于通过直接的生产地接触获取,也不依赖于经常购买日常食品。根据实证分析可以预测,对茶油价值认知度高的消费者将越来越多,需要通过不断消除居民的性别偏好意识、促进教育资源的平等分配,降低接受高等教育的门槛、促进收入合理分配和不断提高居民对健康的关注水平来促进消费者对茶油价值的认知。 相似文献

Exploring land use changes and the role of palm oil production in Indonesia and Malaysia 总被引:1,自引:0,他引:1
This study compiles and analyses national-level data on land use change (LUC) and its causes in Indonesia and Malaysia over the past 30 years. The study also explores the role that palm oil has played in past LUC and that projected growth in palm oil production may play in LUC until 2020 and suggests strategies to minimize negative effects. Data collection for the study revealed that the quality and quantity of data on LUC on a national scale over time are low. Despite these uncertainties, the overview of past LUC indicates that large changes in land use have occurred in Indonesia and Malaysia. In Indonesia, LUC can primarily be characterized by forest cover loss on 40 million ha (Mha) of land, a 30% reduction in forest land. Deforestation in Malaysia has been smaller in both absolute and relative terms, with a forest cover loss of nearly 5 Mha (20% reduction in forest land). Other large changes in Malaysia occurred in permanent cropland (excluding oil palm), which has decreased rapidly since the early 1990s, and in land under oil palm cultivation, which experienced a sharp increase. Projections of additional land demand for palm oil production in 2020 range from 1 to 28 Mha in Indonesia. The demand can be met to a large extent by degraded land if no further deforestation is assumed. In Malaysia, expansion projections range from 0.06 to 5 Mha, but only the lowest projection of oil palm expansion is feasible when only degraded land may be used. The role of palm oil production in future LUC depends on the size of the projected expansion as well as agricultural management factors such as implementation of best management practices, earlier replanting with higher yielding plants, and establishment of new plantations on degraded land. The current use of degraded land needs to be investigated in order to reduce possible indirect LUC, land tenure conflicts, or other social impacts. In addition to minimizing direct and indirect LUC by the palm oil sector, measures that reduce deforestation triggered by other causes must also be implemented. A key element for doing so is better planning and governance of land use, which entails more appropriate demarcation of forest land and protection of land that still has forest cover, improved monitoring of land use, and more research to uncover the complexities and dynamics of the causes and drivers of LUC. 相似文献

The infant industry argument for protection of import competing industries has a long and almost entirely theoretical history in the literature. In this paper the empirical evidence of infant industry dynamics in the Brazilian ethanol industry is investigated. In Brazil ethanol has developed into a primary automotive fuel over the past 18 years. This import substitute is attractive because it allows decreased dependence on international oil supplies while at the same time it addresses environmental concerns because it is a clean-burning renewable fuel. While ethanol was initially a high-cost alternative to imported oil, observed cost reductions have led to an increased belief that this industry may in fact warrant the subsidization it has received because of infant industry reasons. The results of this study suggest that there is no empirical evidence of economies of scale and very little technical change. There appears to be no empirical validity to the infant industry argument for subsidization of the Brazilian ethanol industry. 相似文献
