基于灰关联法的城乡公交分担率影响因素分析

基于非集计理论的思路,利用灰关联分析方法确定公交出行的主要影响因素。该方法对数据的样本量需求小,可以分析出公交特征、个体出行特征和个体特性等因素的变化对公交出行行为的影响。最后采用苍南县城乡公交规划中的数据,通过此种方法得到主要影响因素,再通过SPSS对分组数据进行非线性回归分析,拟合出影响因素与公交分担率之间的函数关系。文章中使用的方法与结论可以为公交系统规划、方案评价、政府及相关部门决策提供参考和支持。     

武夷山市入境旅游客源市场结构分析——基于偏移—份额分析法

偏移—份额分析法是研究区域经济结构极其重要的一种方法[1]。武夷山市风景名胜区是世界级的旅游胜地,其入境旅游客源市场结构变化是武夷山市旅游业发展战略制定的主要影响因素之一。通过运用偏移—份额分析法对武夷山市2004年至2010年12个入境旅游客源市场的旅游人数进行计算与研究分析,结果发现近程市场的港澳台地区、新加坡、马来西亚和日本所占份额比较大;远程市场的美国、加拿大、英国、法国、德国、澳大利亚等这些市场虽然所占份额非常小,但有增长趋势。总体上,武夷山市入境旅游客源市场的竞争能力都较弱,据此建议从加强整体竞争力、提升市场营销能力和市场份额等方面进行改进,以期待对武夷山市入境旅游起到积极的理论指导意义。     

金融抑制、经济结构扭曲与劳动收入份额下降——基于新结构经济学理论的思考

基于新结构经济学理论推行赶超战略的国家倾向于采用金融抑制政策以扶持工业部门、压制服务业部门,造成经济结构工业化的扭曲,而由于工业部门的劳动收入份额偏低,这种结构扭曲致使其劳动收入份额不断走低。使用理论模型与基于跨国面板数据进行实证检验并针对中国的研究发现,样本期中国的劳动收入份额显著低于模型预测值,且缺口趋于扩大;中国严重的金融抑制与经济结构扭曲状况可以解释劳动收入份额约1/3的下偏。     

中国对美国木质林产品出口波动分析

采用联合国统计署2002-2010年的贸易数据, 运用CMS模型对中国出口美国木质林产品的波动进行实证分析。结果表明:竞争力效应是中国出口美国木质林产品增长的主要因素, 结构效应则是中国对美国木质林产品出口波动的最主要动因, 交叉效应作用不明显; 2008-2010年, 受金融危机的影响, 中国及主要国家对美国木质林产品的出口都出现了负增长, 这也体现在增长效应对各国出口显著的抑制作用上。     

COMPETITIVENESS OF MAJOR EXPORTING COUNTRIES AND TURKEY IN THE WORLD FISHERY MARKET: A CONSTANT MARKET SHARE ANALYSIS

ABSTRACT

The purpose of this study is to examine whether and to what extent the shares of selected countries' fishery exports in the world markets reflect their international competitiveness. The Constant Market Share (CMS) model, which decomposes export growth into some broad components (i.e., structural effects, market effects, commodity effects and competitive effects), is applied to examine this issue. The results of decomposition analysis revealed that structural factors have been more significant in explaining the growth of exports. The growth effects, though, appeared positive for each country, the exports of open economies like Canada, the United States, Iceland and Turkey benefited more from the growth of world exports. The analysis of commodity composition and market effects suggests that countries like Canada, the United States, Iceland and Turkey were pursuing the product differentiation policy and were penetrating in those markets, which have been growing relatively faster. These countries remained committed throughout the sample period (i.e., 1980–2000) to export their diversified products in fast-growing markets. The analysis of competitiveness effects, which are derived as a residual, show that Norway, Spain, the United States, Indonesia, Thailand, Chile and China were strong fishery exporters and increased their competitiveness during the sample period.     

哈尔滨市农业结构效益及竞争力的县域比较分析——基于偏离份额分析模型

通过建立偏离份额分析模型和相关指标的定义,对哈尔滨市所辖11个县域的农业经济增长份额、农业结构偏离份额、产业竞争力偏离份额3个分量及其对应的指数进行对比分析,考察哈尔滨市各地区的农业结构效益和竞争力;同时,以哈尔滨市作为标准参照区域对各地区在不同农业产业部门中的结构效益与竞争力进行了比较,分析各县域的农业发展优势;最后笔者针对分析结果提出建议.     

The development of Brazilian aquaculture: Introduced and native species

Brazil’s aquaculture production has increased rapidly during the last two decades, growing from basically zero in the 1980s to over one half million (metric) tons in 2011. However, with an increased focus on the domestic market and native species, the development in Brazil has been very different from most other successful aquaculture producers, particularly in Latin America. As in many other countries, the development started with introduced international species such as shrimp and tilapia in a typical developing country fashion, but has shifted to an increasing share of native species and focus on the domestic market. This article analyzes the main aspects concerning this development by the relative productivity of the main species, regulations and markets. Regulations and the technology spreading from international species may be considered as important factors for this somewhat unusual development. The future prospects for the Brazilian aquaculture industry development are positive, since there is not only space available for expansion for both exotic and native species, but also an untapped domestic market.
