基于DMSP/OLS夜间灯光数据的土地城镇化水平时空测度研究——以环渤海地区为例

在遥感和GIS技术支持下,发展出一种基于长时间序列DMSP/OLS夜间灯光数据的土地城镇化水平测度方法,并以环渤海地区为例进行1992—2010逐年土地城镇化水平时空测度研究。结果表明,在1992—2010年间:1基于DMSP/OLS夜间灯光数据提取的城镇用地信息总体精度和Kappa系数平均值分别达到了88.11%和0.61,能较好地反映区域城镇发展的实际情况,具有一定的可信度;2从总体上看,环渤海地区土地城镇化水平增长迅速,由1992年的0.82%增至2010年的3.20%,年均增长率指数为7.80%;3从区域差异上看,环渤海地区三大城市群之间、滨海城市与非滨海城市之间、距海岸线不同距离的区域之间土地城镇化水平差异显著并呈进一步扩大趋势;4从空间特征上看,土地城镇化水平高值区呈现出一定的向海性。本研究可为快速有效地测度分析区域土地城镇化水平,进而调整和优化区域城镇化格局,推进区域新型城镇化建设提供决策参考。     

旅游业与城市发展的协调度评价——以中国25个主要旅游城市为例

基于改进TOPSIS法和熵权赋值法,分析了中国25个旅游城市的协调水平、空间格局和差异机制。结果表明:125个案例城市可划分为5个等级,分别占总数的4%、8%、32%、40%、16%,协调水平得分的层次结构具有首位度较高,呈两头少、中间多的"橄榄球状";2空间分布上,长三角和珠三角呈现中心城市高、外围城市低的分布特征,中西部地区的区域性中心城市高、其他城市低的特征,东北地区城市之间表现较为一致;3区位条件、城市类型、城市旅游发展阶段和发展模式是四个主要因素,影响城市旅游的客源市场规模、旅游经济收入、城市产业结构、旅游投资收益,使得城市旅游与城市发展之间的协调水平出现较大差距。鉴于此,不同区域应根据城市性质、发展阶段、资源禀赋和区位条件选择合理的城市旅游发展模式,为城市和旅游的融合发展提供良好环境,深化旅游业在城市发展中的作用。     

Income and Quality of Life: Does the Love of Money Make a Difference?

This paper examines a model of income and quality of life that controls the love of money, job satisfaction, gender, and marital status and treats employment status (full-time versus part-time), income level, and gender as moderators. For the whole sample, income was not significantly related to quality of life when this path was examined alone. When all variables were controlled, income was negatively related to quality of life. When (1) the love of money was negatively correlated to job satisfaction and (2) job satisfaction was positively related to both income and quality of life, income was negatively related to quality of life for full-time, high-income, and male employees. When these two conditions failed to exist, income was not related to quality of life for part-time, median- or low-income, and female employees. This model provides new insights regarding the impact of the love of money and job satisfaction on the income–quality of life relationship.

中国互联网发展水平测度指标体系研究

本文认为,在国家实施以信息化带动工业化战略的背景下,互联网作为信息化发展的龙头,对其进行测度具有十分重要的意义。本文从互联网基础设施、互联网普及、互联网初级应用、互联网高级应用等四个方面选取8个二级指标建立了我国互联网发展水平测度指标体系,并采用层次分析法确定各指标权重,从而为测度我国及各地区互联网发展水平,进而为政府部门制定互联网及信息化发展政策,分析各地区互联网发展差距,提供了一个较为科学的方法。     

访华日本国际客源市场之细分研究

日本作为国际客源市场形成于其高速发展的经济成长期,在中国改革开放后,这一市场对中国国际客源市场的发展产生着极为重要的影响.然而,依其市场规模和显在的经济实力,实际访华的日本客源市场规模远未达到预期,这对中国在今后争取更大的日本客源市场乃至亚洲客源市场来说,是一个值得探讨的课题.本文想透过该问题的研究,全面分析访华日本国际客源市场的状况,并据此为中国在争取日本国际客源市场方面提供一个科学的参考依据.     

广告对社会福利的影响及最优投放水平分析

过度竞争、进入壁垒与流通组织优化

过度竞争是流通产业健康运行的重要障碍。文章从产品同质性和产品差异化两个角度,运用扩展的伯川德模型和萨洛普模型,分析了过度竞争在流通产业中出现的必然性,即流通产业自由进入的特点决定了过度竞争的存在。然后运用斯塔尔博格模型,采用跨期分析,指出了流通企业选择合适的投资水平可以阻止潜在进入者,避免过度竞争的发生。最后,提出了优化流通组织的建议。     

基于AHP的航空货运客户价值细分方法研究

在资源有限的条件下,企业必须将资源投放到那些有利可图的客户上,因此有必要进行客户细分,对于处在激烈竞争环境中的航空货运尤其如此。本文借鉴客户价值细分理论,以客户的当前价值和增值价值为细分依据,提出基于层次分析法的航空货运客户价值细分方法。     

关于优化我国政府级次的构想

我国是世界上政府层级最多的国家,设有中央、省(自治区、直辖市)、市(自治州、地区)、县(自治县、市)、乡(民族乡、镇)五级政府。随着构建公共行政、程序行政和责任行政为主体的"服务型"政府管理体制改革的推进,这种"金字塔"型的政府级次的弊端越来越明显,减少中间层次,扩大管理幅度,构建扁平化的政府级次势在必行,即将五级政府扁平化为中央政府、省政府和基层政府的三级政府。     

农民收入水平对农村家庭能源消费结构影响的实证分析

本文依据调查资料,利用层次分析法实证分析了农民收入水平对农村家庭能源消费结构的影响,得出结论:农户的收入水平对农村家庭生活用能源种类的选择影响较大,因此不同收入水平的农户家庭能源消费的结构存在较大的差异;人均收入在4000元以下的农户,户用沼气的权系数最大,人均收入超过4000元的农户,液化气的权系数最大;农户的收入越高,对能源的舒适性、便利性、卫生特性的要求越高,农户的收入越低,对能源的经济性则考虑得越多;使用无成本、又便利的户用沼气非常适合在收入水平较低的农村地区推广。
