人口结构对农村居民消费率的影响分析——基于1995-2009年省际面板数据

研究中国人口结构对农村居民消费率的影响对刺激农民消费、扩大内需、推进经济转型,以及保障中国经济持续稳定增长具有重要意义.利用中国1995-2009年省际面板数据,运用普通固定效应回归、动态面板系统GMM估计和差分GMM估计方法进行比较,结果显示:由于农民消费的惯性和消费习惯的存在,纯收入增长率、消费价格指数变化率等对其消费率的贡献不显著,财政支农政策的影响仍然是有争议的,农村居民性别比的降低、家庭规模的缩小以及抚养比减少等人口结构的改变是现阶段中国各地区农村居民消费率持续走低的重要原因.     

麦角新碱人工抗原的合成及鉴定

以麦角新碱为起始原料,通过琥珀酸酐法合成麦角新碱的半抗原,再采用EDC法使该半抗原与载体蛋白偶联得到麦角新碱的人工抗原。分别采用紫外吸收光谱法和基质辅助激光解吸-电离飞行时间质谱法(matrix-assisted laser desorption/ionization time-of-flight mass spectrometry,MALDI-TOF-MS)测定制备的免疫抗原(麦角新碱-BSA)的偶联结合比。结果表明,2种方法测得的麦角新碱与载体蛋白偶联比分别为12∶1和17∶1。此外,红外光谱法鉴定结果进一步表明人工抗原合成成功。通过麦角新碱免疫抗原免疫新西兰大白兔,获得了高效价抗血清,最终证明麦角新碱人工抗原合成成功。     

Land suitability evaluation for development using a matter-element model: A case study in Zengcheng, Guangzhou, China

Land suitability evaluation can assist in the efficient use of land resources at a regional level. This is an important issue because of the pressures that an increasing population and economic growth have put on limited land resources. Matter-element theory, which was first put forward by the Chinese mathematician Cai Wen, has shown potential for solving incompatibility problems. Based on the matter-element model, this paper uses land use, roads, water bodies, population density, distance from center of the city, geodetic height, and slope as factors in modeling land suitability for development. Zengcheng, an urban-rural administration was used as a case study for applying the matter-element model to assessing the suitability of land for development. The model was cross referenced with local urban plans for verification and the results of this study show that the model constructed was effective at assessing the suitability of land for development. According to both the classification map created using the matter-element model and the statistics on the of land suitability classes, the study area was found to have a considerable amount of land which is highly suitable for development. After the category ‘highly suitable’, the next largest total land area was in the category of ‘not suitable’ for development, while there was relatively little land classified as moderately and marginally suitable. The percentage of the total land area of each class of suitability was 41.80%, 34.22%, 16.35% and 7.64%, respectively. Apart from this, the study also demonstrated the advantage of matter-element models over fuzzy theory, as they provide much more information. For example, all integrated degree of all classes in the paper had ranges from −1 to 1, but differed from each other by percentage. In the category of ‘highly suitable’ only 45.51% of matter-elements fully conformed to the criteria (those within a range of 0-0.5925), while the remainder (54.49%) did not corresponded to the requirements of the category, but did have the potential to do so with relatively few changes (those within a range of −0.3923-0 degrees). This data provides us with an understanding of the potential and limitation to development of the land in the region.

中国式“荷兰病”与外来直接投资研究

本文从来源于加入WTO后外向型劳动密集型产业繁荣的中国式"荷兰病"理论出发,深入细致地分析了中国式荷兰病通过"支出效应"、"资源转移效应"、"人民币汇率效应"、"体制惰性效应"以及"技术创新效应"等对中国外来直接投资的诸多影响。文章实证研究发现,持续、大规模涌入我国的外来直接投资不仅投资产业和流入方式发生了巨大变化,而且在推动我国对外贸易和贸易顺差迅速扩大的同时,进一步强化了中国式荷兰病和我国出口导向型经济增长方式。文章最后建议制定国家中长期产业发展规划及相关产业政策,及时赋予外商投资企业以国民待遇,适时扩大人民币汇率浮动区间,切实鼓励国内企业对外直接投资,从而确保我国经济增长方式转变与经济增长质量提高。     

管子学派立法理论探析

管子学派以“法天合德”作为政权立法的法理依据;以社会发展规律、社会成员的一般知识水准和行为习惯作为立法的现实依据。管子学派将法律分为九类并界定了各自的特征;提出了详细的立法调查提纲和立法论证原则;确定了严格的法律颁布程序;论证了法律语言的具体要求。管子学派的立法理论影响了中国封建政权的立法活动。     

浅析大连乡村旅游的发展

大连乡村旅游业的发展是大连旅游业发展的重要一环。大连市的乡村旅游虽然在总体上取得了较明显的发展,但是在发展的过程中也发现一些问题,主要是乡村旅游服务质量不高,大连乡村旅游人才缺少,管理水平低下,大连乡村旅游活动单一,缺乏新意,千篇一律等。乡村旅游是一项关联性和综合性很强的产业,要实现乡村旅游产业的长久良好持续发展,需要全社会、政府、旅游经营者的共同努力。大连市政府相关部门应做好乡村旅游的规划,科学制定发展计划;大力加强基础设施的建设;注意培养引进乡村旅游人才,提高素质,提高乡村旅游的接待水平;发展特色的乡村旅游项目;采取多种方式,扩大大连乡村旅游知名度,以此促进大连乡村旅游可持续的发展。     

Traditional culture,political ideologies,materialism and luxury consumption in China

China is now the second largest luxury market in the world. This study examines the effect of traditional Chinese cultural values and support for political ideologies on materialism and interest in luxury products. Results showed that both traditional Chinese cultural values (face, harmony and guanxi) and political ideology (Maoism vs. Deng's theory) influenced materialistic aspirations and interest in luxury products. This suggests that researchers should also consider the influence of political ideology as much as they consider cultural values, as many developing societies are in transition.
