根据日本物流业的市场规模,对日本贷物运输发展及现状进行分析,通过货物总运输量与纯运输量的区别与比较,从货物品种比率的变化、货物附加值的变化,分析日本物流业的发展水平。分析了日本产业结构的变化、消费结构的变化和市场需求的变化对日本运输体系和物流业的发展变化的影响。     

港口企业绩效计划改进探讨

绩效管理需要持续改进。不论对于组织绩效还是个人绩效，绩效计划的优劣都直接影响绩效管理的最终结果。因此，绩效管理的难点在于绩效计划的制定。笔者以宁波港股份有限公司为例，着重探讨港口企业绩效计划的改进。     

震荡油价走势推断模型的确立

本文用随机过程理论对震荡期油价序列进行了讨论,证实其为马尔柯夫链,并以马尔柯夫链的极限概率为依据,建立了油价序列的中长期推断模型。进而文章又对该序列进行了概率分布检验,证实对数正态分布是其经验分布的最佳拟合,并以此作为依据建立了油价走势的近期推断模型。文章指出,将这二者结合起来,构成油价时间序列由近期到中长期的一个完整的推断模型。作者用此模型对油价走势所作的推断与油价实际走势是相吻合,证实了模型的可信性和实用性。此外,用此模型还揭示出今后可能出现新一轮的国际油价飙升期。     

《淮南子》“秦始皇”观评议

《淮南子》多次论及"秦始皇",从社会经济、政治用人、现实战争及法治实践等方面,对其暴虐之政进行严厉批判。着眼于治术、治道及君道,《淮南子》从道、儒立场出发,深刻反思秦政之失,认为其根由在于秦始皇迷信法家的功利政治,并将其在实践上推向极端化,以致秦王朝缺失"民本"的正义性内涵,最终在纵欲残民、与民为仇中败亡。对秦始皇的暴政之失,《淮南子》试图让统治者深有借鉴,以此促使其在治国上民本为先、身国同治,延续清静无为、休养生息的汉初国策,推动西汉王朝实现"圣王"之治。     

Local elections and consumption insurance

During our sample period from 1987 to 2002, Chinese villages completed the transition from government‐appointed village leaders to elected ones. This article examines if and how much democratic elections of the village leaders affected consumption insurance by Chinese village residents. Exploring a panel dataset of 1,400 households from this period, we find that consumption insurance is around 20 percent more complete with elected village leaders. Furthermore, local elections improve consumption insurance only for the poor and middle‐income farmers, but not for the rich. The results are robust when we allow for pretrending, potential endogeneity of elections, and higher measurement errors for rich residents. We also find that the effects on consumption insurance are stronger when closer to the upcoming election year and when the village committees consist largely of non‐Communist Party members. These findings suggest that the election effects on consumption insurance partly come from increasing accountability to local constituents.

Minimizing Group Discordance Optimization Model for Deriving Expert Weights

This paper focuses on the problem of how to determine expert weights in multiple attribute group decision making. We first aggregate all the individual decision matrices into the collective decision matrix by means of the weighted arithmetic averaging operator, and then from the angle of minimizing group discordance, we establish a general nonlinear optimization model based on deviation function, and employ a genetic algorithm to solve our model so as to find the optimal expert weights. Moreover, we extend our model to uncertain multiple attribute group decision making, where the attribute values are interval numbers, and finally, apply our model to the plan evaluation of new model of cars of an investment company.     

碳生产率的差异与低碳经济结构调整——基于沪陕投入产出表的比较研究

利用投入产出数据,本文计算并比较了沪陕两地的碳生产率,发现碳生产率存在明显的地区差异和行业差异。碳生产率的地区差异表明各地区实施侧重点不同的低碳经济结构调整可以有效降低我国的碳排放总量;地区内部的低碳经济结构调整除应该关注碳生产率的行业差异外,还应该充分考虑产业关联对碳排放总量的影响。行业影响力低、碳排放的影响力高的行业是沪陕两地低碳经济结构的重点。
