城市旧住宅小区管理模式研究

城市旧住宅小区管理模式有物业管理模式、社区管理模式和单位自管模式之分。旧小区管理模式改革和创新是建立政府行政管理与居民(业主)自治管理相结合、社区管理与物业管理相结合的混合型管理模式,其实现途径是加强政府对旧小区管理的领导和支持,充分发挥小区自治组织的作用,积极推行物业管理模式,更新思想观念,提高物业管理服务水平,建立物业管理与社区管理相结合的运作机制,加强法制建理服务设。     

METROPOLITAN HOUSE PRICES IN SOUTH AFRICA: DO THEY CONVERGE?

The question this paper investigates is whether or not different metropolitan areas each constitute a separate housing market or whether or not there is a single South African housing market. Theory on the Law of One Price suggests that if products or geographic areas belong in the same market, their absolute prices must converge, so that their relative prices are stationary. By using cross-sectional time series data of five metropolitan areas, the paper tests for the Law of One Price by applying the Im, Pesaran and Shin panel unit root test. The paper finds strong evidence of convergence in large middle-segment house prices and weaker support for convergence in medium middle-segment house prices. In addition, the paper finds no evidence for convergence in small middle-segment house prices. This suggests the existence of a national market for large and possibly middle-segment houses in metropolitan areas, but separate metropolitan markets for small middle-segment houses. In addition, the paper estimates the speed of convergence and finds that large middle-segment house prices converge within two to seven quarters, while the speed of convergence for medium middle-segment house prices in three of the five areas is five to eight quarters.     

关于纺织服装业推进物流发展的思考

现代国民经济的主要载体是城市经济;现代城市经济发展的关键环节都离不开物流业;山东发展纺织服装物流业的重要特点是,把行业物流业同城市物流业发展紧密地结合起来;现代物流业已经成为现代城市经济的重要组成部分。在现代国际市场竞争日趋激烈的趋势下,发展行业与城市现代物流业成为非常重要的问题。

基于Panel—Data模型的山东省区域旅游问题研究

旅游业已被公认为“朝阳产业”、“无烟工业”，是集吃、住、行、游、购、娱为一体的综合性很强的产业，其光明的发展前景已为世人所公认。旅游业对其相关产业的牵动比例为1：4，可以充分带动地方经济的发展，发展潜力很大。本文运用了山东省17地市的国内旅游情况的合成数据，通过建立完整的计量模型，进行计量分析，进而发现各地市每增加一万人次的旅游者，对该地区的旅游经济的影响存在一定的差异，并且对于差异进行聚类分析，得出全省各地市的不同属类，为山东省日后旅游市场的更好发展提出了一些相应的建议。

Wage and Price Inflation in Poland in the Period of Transition: The Cointegration Analysis

The paper focuses on the long run relationships between wages, prices and labour productivity in the Polish economy by applying recent developments in the field of multivariate cointegration analysis. We followed modeling strategy which is suggested by Greenslade et al. (1999) and present all stages of the analysis which leads to the fully economically identified system of equations representing long run relationships. The investigation is based on the quarterly data from 1992.1 to 1999.2 which covers the period of transition of the Polish economy from the centrally planned system towards the market one. Basing on the empirical results we can argue that wages (costs) were one of the main forces driving inflation in Poland during that period. Also labor productivity proved to be stimulated by the increase of the real wages. On the other hand the hypothesis concerning the relationship between wages and unemployment was rejected by the data.
