结构性进入壁垒与行政性进入壁垒——基于租金分析范式的理解

本文基于租金分析范式将市场进入壁垒分为内生的结构性壁垒和外生的行政性壁垒,并进一步将后者分为能给在位企业带来额外收益的第Ⅰ类行政性进入壁垒和对企业施加了额外成本的第Ⅱ类行政性进入壁垒.企业寻求市场内生性的结构性进入壁垒会产生出有效产出,而寻求或者规避外生性的行政性进入壁垒则会导致与效率目标相冲突的逆向激励.

Competition in Marketing： Survival Yardstick for Small and Medium Enterprises （SMEs） in Nigeria

The topic investigated competition in marketing as a survival yardstick for small and medium enterprises （SMEs） in Nigeria. The objectives addressed by this study were： （1） identifying different types and intensity of competition that SMEs are exposed to along the life-cycle portfolio in Nigeria; （2） quantifying the strength of SMEs vis-a-vis some foreign enterprises in terms of market competition; and （3） proffering solutions on how best they could match competitively these foreign enterprises. Relevant models and theories were employed in literature to evolve detailed analysis of issues relating to the variables used in terms of competition in marketing and survival of juice-producing SMEs. Two hypotheses were investigated through the survey of 20 prominent Ikeja based SMEs using Cluster sampling, 5-points Likert summated rating scale was adopted, while Yard＇s formula with 95% confidence level and 5% error tolerance was used. Alternative form validity of the instrument was measured at 0.63 while its reliability was measured at Cronbach＇s alpha of 0.70. Pearson＇s product-moment correlation was used in testing hypothesis 1 while standard multiple regressions were used to test hypothesis 2. Findings revealed that there was strong relationship between survival of juice-producing SMEs with forms of competition on a firm＇s life-cycle; while competition had positive effects on survival components for the enterprises. It was concluded that since competition subsists in any firm＇s life-cycle, strategies to support operations for survival must be adopted. It was recommended that operators of SMEs have to monitor and manage competition as it affects their businesses positively and/or negatively.     

四川古蔺河水质的生物毒性评价

随着工农业的快速发展和人类活动的日益增加,大量废水随之产生,这些经过或未经过处理的废水最终排入河流等水体中,对水体水质造成极大的负面影响.该实验应用玉米种子萌发毒性检测和蚕豆根尖微核实验,对四川省泸州市古蔺河8个采水点的水样进行了生物毒性测试.结果显示,沙坝等8个采样点的水样均会导致蚕豆产生一定程度的微核,显示出一定的遗传毒性效应,其中4个采样点的水质达到中污染的水平.玉米种子萌发毒性试验结果表明,永乐镇等5个采样点的水样对于玉米种子的发芽率和根生长有比较明显的抑制作用.这表明古蔺河下游水质受到污染,有潜在生物毒性.     

助贷违约学生行为成因及防范对策研究

国家助学贷款为高校贫困生完成学业、促进教育公平起到很大的作用,但我国在实施国家助学贷款政策过程中,由于有的学生偿还能力较低、偿还意愿较差,贷款制度设计欠缺,社会信用环境不佳等原因,发生学生助学贷款违约行为,贷款违约率较高,加大了政府、高校和银行管理成本,制约着助学贷款的持续良性发展。解决这些问题,应从提高高校教育质量、增强学生诚信意识、建立社会信用体系、完善贷款制度设计、健全高校资助制度等方面采取有效措施。     

How to price the unbundled local loop in the transition from copper to fiber access networks?

In many countries worldwide access networks are in the transition from copper to fiber access. During the transition phase copper and fiber networks are operated in parallel. All regulators facing this situation of technological change have to decide how to price unbundled access to the copper loop in this transition phase. Should they keep the usual forward looking long-run incremental cost standard charge, or should they move to some different approach? The authors propose to price copper access based on the modern equivalent asset (MEA) of fiber access. Since fiber access is superior to copper access, the cost of fiber access (as a basis for pricing copper access) should, however, be corrected by the performance delta between copper and fiber access.
