This study examines the impact of microcredit on household self‐employment profits in Vietnam. For two indicators of credit participation – a dichotomous participation dummy and the accumulated amount of microcredit received per household – the analysis reveals a positive effect on household profits. The analysis also reveals that an instrumental variable method within a fixed‐effects framework can control for the possible endogeneity of credit and thereby identify the true effect of credit. 相似文献

This article investigates the elasticity of different technology choices to energy efficiency and chemical oxygen demand/ammonia nitrogen emission reducing efficiency among 38 industries in China from 2008 to 2011. With data envelopment analysis, total-factor productivity growth, the common measure of technical progress, is divided into different parts: technical efficiency relative to the frontier, technology change and scale efficiency, which are regarded as three different choices of technological progress. For various industries, technology elasticity is quite different and the importance of different technical choices is diverse in the improvement of efficiency on energy saving and emission reduction. Policymakers could focus on the elasticity of different technical progress choices in various industries to improve energy and emission reduction efficiency. 相似文献

Sodium content in foods: Brazilian consumers’ opinions,subjective knowledge and purchase intent 下载免费PDF全文
Jéssica F. Rodrigues Rafaela C. Pereira Andressa A. Silva Andrey O. Mendes João de Deus S. Carneiro 《International Journal of Consumer Studies》2017,41(6):735-744
This study attempted to gain insights on Brazilian consumers’ subjective knowledge of sodium content in processed and homemade foods and their purchase intent for products with reduced‐sodium content. A questionnaire was distributed to 409 consumers selected by convenience quota sampling. We found that Brazilian consumers were concerned about the amount of salt (sodium chloride) in the products they consumed, regardless of educational levels, income, age, lifestyles, or health conditions. However, they still considered their consumption to be above WHO‐recommended limits and had little subjective knowledge about the term ‘sodium’. While processed products were considered the main contributors of high‐sodium intake, participants were not concerned about addition of salt at the table and salt in homemade food. The majority of respondents rarely read the sodium content on food labels; however, men and older individuals were more likely to read label information on sodium content. Products with reduced sodium were found to have market appeal, which justifies investments in research to develop these products. Therefore, in addition to the efforts to reduce sodium in the processed‐food industry, it is necessary to promote awareness about the importance of food labelling, especially sodium content, and the need to reduce salt in homemade food and additions during meals. 相似文献

Reduction in nitrogen fertilizer use results in increased rice yields and improved environmental protection 总被引:1,自引:0,他引:1
Overuse of nitrogen fertilizer represents a considerable environmental problem globally, but especially in China. Recently, a recent approach on an experimental scale based on the diffusion of the so-called Three-Control Technology (TCT) successfully alleviated the overuse of nitrogen fertilizer in southern China villages in the Guangdong Province, serving as a reference point for other rice-producing countries tackling similar challenges. Here, we assessed the correlation between rice yields and reduction in the use of nitrogen fertilizer following the introduction of TCT. Our study was based on the collection of primary data from 248 households randomly selected from four rice-growing areas of Guangdong Province, China. Our results show that TCT significantly improved the efficiency in the use of nitrogen. Crucially, participating farmers, including both full adopters and partial adopters, were found to fundamentally change their application practices of nitrogen fertilizer, resulting in major improvements in the local soil and water systems. 相似文献

This paper analyzes the relationship between local poverty and food manufacturing growth in Chile and Mexico using propensity score matching, differences in differences and spatial econometrics methods. We focus on food manufacturing as a sector with a number of characteristics that make it potentially pro-poor, and whose incentives for spatial distribution may either strengthen or dampen its poverty reduction potential. The overall results indicate growth in food manufacturing employment contributes to local poverty reduction. 相似文献

本文研究了日本在应对气候变化方面提出的国际机制建议,对其提出的后京都时期的政策,尤其是其倡导的行业减排机制进行了深入研究,并以日本钢铁联盟应对气候变化行业减排的案例进行了分析,指出了国际应对气候变化斗争的新动向,为我国的国际谈判对策提供了研究基础。在当前应对气候变化的形势日益迫切的情况下,中国要充分借鉴日本的先进经验,采取积极的战略和策略应对气候变化,并使之与国家可持续发展战略和科技创新战略相结合,与国家重大生态建设工程、节能工程和能源产业技术升级工程相结合,与国家能源、环境等方面的法律、法规和政策体系建设相结合,增强国家应对气候变化的能力,并在后京都国际减排机制中发挥建设性的作用。 相似文献

资源与能源的无节制消耗,致使全球环境污染和资源枯竭。我国对资源和能源的巨大消费受到全球瞩目,能否及时有效地出台节能减排的政策措施,并尽快达到国际节能减排标准,不仅是国际社会的期望,也是关系到我国科学发展的大计。文章从节能减排、资源节约和资源环境保护相互关系的认识入手,提出政府应采取法律、价格、财税、金融相互协调的综合手段和配套措施推进节能减排。 相似文献

本文利用1978~2008年的时间序列数据,运用脉冲响应函数和方差分解技术考察化肥价格波动与农民收入之间的关系,发现化肥价格的波动与农民收入变化之间存在着双向的因果关系,即化肥价格的上涨导致农民增收缓慢,而化肥价格上涨的根本原因在于"需求拉动"和"成本推动"。今后必须从需求和供给两方面采取对策:一方面通过建立化肥直接补贴制度和化肥储备制度,从需求上控制化肥价格上涨;另一方面通过采用新型化肥生产技术和给予化肥生产企业生产用能以优惠政策,从供给上控制化肥价格上涨。 相似文献
