醋酐市场分析及工艺技术 总被引:1,自引:0,他引:1
醋酐是最重要的精细化工原料之一,主要用于合成醋酸纤维素,其次用于医药、染料、香料和有机合成中的乙酰化剂。2009年中国有醋酐生产企业17家,总生产能力约为51万t/a。国内醋酐装置规模较小,工艺落后,今后应逐步淘汰落后装置,实现规模化生产,以降低生产成本,提高经济效益。发展技术先进的羰基合成工艺具有广阔的前景。 相似文献

This study was designed as an application of Becker's household production function approach to the production of a household commodity, in this case care of clothes and household linen. The production function and the derived input demand functions for the inputs into the production were formulated. Hence, the attempt was made to look at the whole system of functions that are relevant with respect to the production of clean clothes in the household, trying to uncover the interrelations and interdependencies in household production. 相似文献

The purpose of the study was to examine the relationship between the extent of household production and satisfaction with household production. Data were obtained from 400 married couples who responded to a postal questionnaire. The dependent variable was an index of satisfaction incorporating two aspects of household production, quality and quantity. Regression analysis indicated that of the three variables representing the extent of household production in the model — hours spent by each spouse in household production and an activity index to measure the number of household production activities — only husband's hours spent in household production demonstrated a significant, independent effect. Other significant variables included husband's hours of market work, household net worth, age of respondent and gender of respondent. Two significant interactions indicated that (i) the relationship between wife's hours of household production and satisfaction with household production differed according to the gender of the respondent, and (ii) the relationship of husband's hours of market work and satisfaction differed according to the age of the respondent. 相似文献

Drawing on internalization theory and economic geography research, we examine how the spatial structure of MNE subsidiaries in supranational regions affects subsidiary location choices. Our analysis of foreign production investments by Japanese manufacturing firms from 1971 to 2006 supports our theoretical predictions: firms were more likely to establish new production subsidiaries in countries geographically more proximate to existing production subsidiaries, but not to trading subsidiaries, in the same region. The proximity effect diminished for production subsidiaries engaged in accessing natural resources or R&D. Performance of production subsidiaries was also stronger for those closer to other production subsidiaries in the same region. 相似文献
