西北地区的生态旅游与可持续发展

西北地区旅游业的发展应坚持可持续发展的生态旅游.因为西北地区发展生态旅游有着丰富的旅游资源和良好的市场前景。进入20世纪90年代尤其是1993年以来,全国旅游业发展迅猛,旅游市场走俏。国际市场稳步扩大,国际旅游外汇收入由1986年的世界第20位,上升到1997年的第9位,接待人数     

付华廷与富华集团:打造龙江第一村的新农村风采

当你来到黑龙江省甘南县音河镇兴十四村,那么你关于乡村的概念以及城市生活的优越感会可能会全部崩溃.从齐齐哈尔市向西北行约80公里,高耸入云的“中国富华国际生态产业园”映入眼帘,这就是“龙江第一村”兴十四村的“村标”了.平整洁净的水泥路面延伸过去,豁然展开的是一个面积为3.5万平方米的休闲广场,阳光下音乐喷泉喷射着清凉耀眼的水柱;周边绿树红花中,掩映着一百多栋红顶黄墙的民居别墅和一座三星级宾馆.远处,正在建设中的高大厂房弧光闪烁.你不能相信这是一个村庄,更不能想象这个村庄位于偏远的、至今不通铁路的黑龙江省甘南县.

Do homeowners achieve more household wealth in the long run?

Despite the public’s faith in homeownership as a vehicle for wealth creation, there are surprisingly few empirical studies of the independent impact of homeownership and its duration on household wealth accumulation. This paper provides the first empirical evidence that homeownership, after controlling for other drivers of wealth accumulation, is positively and significantly associated with wealth accumulation over time. Using the Panel Survey of Income Dynamics, it examines the influence of housing tenure choices between 1989 and 2001 on household net wealth levels in 2001 after controlling for initial wealth in 1989, location, income, education, and other family and personal characteristics that might influence the rate of wealth accumulation. Importantly, the models used also control for the tendency of households to accumulate wealth between 1984 and 1989 (five years prior to the studied period). This approach is used to address the possibility that an unobserved variable—the propensity to save or accumulate wealth—may be associated with both the probability and duration of homeownership and the rate of wealth accumulation. All else equal, those who owned homes and owned for longer periods of time had significantly higher household net wealth by 2001. These results are compelling because house price appreciation over the period was near its long-run average while stock gains were above and real rent increases below their long-run averages. Hence, the findings are suggestive of a positive influence of ownership over long periods on net wealth, even during a period when alternative investments produced higher than normal returns and rents grew slowly. This is especially important because the overwhelmingly majority of households do not sell their homes shortly after buying them. In our sample, those who became owners typically owned for 7 years. Furthermore, most households that bought during a period of declining real home values in the early 1990s continued to own their homes for at least eight years and came out well ahead of those who did not own.     

CEV模型的单位根检验研究

CEV模型（Constant Elasticity of Variance Model）作为常用的利率模型，在实证分析中得到了广泛运用，但是其单位根检验一直被忽略或者被默认可以使用迪基一富勒检验。本文首次运用Box—Cox变换的技巧，针对CEV模型的单位根检验问题，找到了合适的统计量并且证明其渐进分布存在，然后通过蒙特卡罗方法求出了该统计量的分布表。得到了在大样本的情形下可以沿用迪基一富勒检验，但在小样本的情形下与迪基一富勒检验有所偏差的结论。     

拓宽扶贫思路,构建和谐社会

改革开放以来,我国扶贫工作成绩显著.全国贫困人口已从30%降至4%,但目前无论相对贫困还是绝对贫困,情况仍然十分严重.绝对贫困方面,全国农村低于国家规定的贫困线(人均年收入667元人民币)的人口有2 600多万,其温饱问题还未完全解决;全国城镇低于低保线(人均月收入159元人民币)的人口有2 200多万,生活状况仍十分艰难.     

完善城市整体功能是旧城改造的方向

城市的更新、改造是社会发展的必然 ,如何通过现状调查、分析、研讨 ,找出城市建设的症结 ,使城市趋于完美是城市建设者的历史使命。但现实中 ,片面追求经济效益 ,发旧城改造之财 ,只能使城市变成“崭新的旧城” ,只有按城市发展的固有规律去完善城市的整体功能才是旧城改造的发展方向。
