台湾地区主要林产品产值变动趋势测度研究——兼论闽台林业产业合作路径

在厘清主要林产品和产值这两个重要概念的基础上,以2010年台湾地区统计年鉴中的《林业产品生产量值》为样本对象,选取用材、薪材、枝梢材和竹材等产值对数以及林产品总产值对数这5个变量作为研究变量,采用ARMA模型对台湾地区主要林产品产值的变动趋势进行测度;得出关于台湾地区林产品价值变动机理的4个重要结论;最后结合当前海峡两岸的经贸背景,提出促进闽台林业产业深度合作的四条路径。     

基于耗散结构理论的住房市场消费及其调控

本文从我国某些城市住宅市场"异动"及其危害性入手运用耗散结构论,分析说明住宅市场实现供求从"无序"向"有序"转化的机理和桥梁。阐述了房地产市场系统"涨落"的必然性及其影响因素,提出了宏观调控房地产市场的根本手段:一方面,要创造非平衡条件,即规定使用者占有或使用房地产资源的成本和限制条件;另一方面,要尽量减少系统流动阻力,即要保证房地产市场信息的透明度和资金供应的合理与畅通。     

Tourist behavioural intentions in relation to service quality and customer satisfaction in Kinmen National Park,Taiwan

This study assesses tourist satisfaction and its links with service quality using a hierarchical model that combines four primary determinants and eight corresponding sub‐dimensions. A sample of 616 tourists departing from Kinmen Airport was surveyed with a structured questionnaire after they had just visited Kinmen National Park. A series of analyses was performed to explore tourist satisfaction with the four main service quality attributes as well as their willingness of repeat visits and recommendation. As a result, it was consistently found that service quality has positive significant relationship with tourist satisfaction. It is thus suggested that national park managers have to satisfy tourists with a high level of service quality, based on the concept that service quality may have a significant influence on long‐term behavioural intentions through high levels of customer satisfaction.

生产性服务业对制造业前向和后向技术溢出效应检验

本文分析了生产性服务业通过前向关联和后向关联对制造业产生技术溢出效应的内在机理。运用1999—2008年制造业行业面板数据实证检验技术溢出效应,并基于不同要素密集类型制造业和三大经济带制造业进行相应分析。得出如下结论：（1）FDI是制造业技术进步的主要原因,生产性服务业对制造业技术效率产生前向的正溢出效应,后向溢出效应不显著。（2）生产性服务业对资本密集型制造业技术效率前向正溢出效应最强,对技术密集型制造业产生微弱的后向正溢出效应。（3）长三角地区生产性服务业对制造业技术效率产生前向正溢出效应,环渤海经济圈和珠三角地区与之相反,生产性服务业对制造业产生后向正溢出效应。

Technical efficiency relative to a stochastic cost frontier for the England and Wales dairy sector

It has been acknowledged in the literature that productive efficiency in grain production in China has substantially improved in the post-reform period, particularly in the early 1980s. Since then, there have been several policy changes in China, which have affected the growth of the sector. Specifically, the spectacular growth of rural industries has attracted significant physical and human capital from agriculture. It is in this context that Brown's warning of China soon becoming the world's number one importer of grain has raised an important question of whether China has reached its grain production potential. Analysis of the 1994 farm household survey data indicates that the majority of the sample farmers is reasonably technically efficient in grain production but that productivity can be increased further even with the existing technology.     

超声波辅助提取黑豆油及其脂肪酸组成分析

采用超声波辅助法,以石油醚为溶剂提取黑豆油。考察了提取时间、提取温度、料液比和超声波功率对黑豆油提取效果的影响。结果表明,提取黑豆油的优化工艺条件为：提取时间9rain,提取温度58℃,料液比1：9,超声功率110W,在此条件下,黑豆油得率达到83．83％。对黑豆油进行GC—MS分析可知,黑豆油的主要脂肪酸有棕榈酸19．24％、亚油酸46．28％、油酸18．62％和硬脂酸7．3％等,其不饱和脂肪酸含量达68．98％。     

樱桃酸奶工艺技术研究

以樱桃、鲜牛奶为主要原料,加入保加利亚乳杆菌与嗜热链球菌进行混茵发酵制作樱桃酸奶,研究了樱桃和鲜牛奶的比例、菌种添加量、pH、白砂糖添加量对成品的影响,应用正交试验确定樱桃酸奶的最佳工艺。结果表明,樱桃酸奶发酵工艺的最佳配方为：樱桃汁与鲜牛奶的比例1：8,白砂糖添加量8％,接种量60／o,发酵pH5．5,以此工艺条件可生产出酸甜可口、果香浓郁、性质稳定的营养保健樱桃酸奶。     

黑龙江省城市土地利用效益时空差异分析

城市土地利用效益是衡量城市土地利用水平的一项重要指标.文章从经济一社会一生态三个方面构建适合黑龙江省城市土地利用效益评价的指标体系,运用最优组合赋权法和协调度对黑龙江省12个地级市2002-2009年间城市土地利用综合效益水平进行分析比较;以评价结果为样本点,通过聚类分析得出全省城市土地利用综合效益水平的空间分布差异.结果表明:在时问上,12个地级市的土地利用效益水平呈现不同变化趋势;根据评价结果将12个城市分为土地利用高效益地区、中等效益地区和低效益地区三大类;在空间上,城市土地利用效益水平呈现"T"型的分布特征,"T"型区域内城市用地效益水平高于其它地区.
