简析中日能源联合议价的成本收益

作为世界第二和第三的大能源消费国,中国和日本在分散竞争的条件下承受了过多的进口成本。本文在分析能源商品的价格决定因素基础上,探讨中日两国进行能源联合议价的成本与收益。认为这种努力可以在消除能源的亚洲溢价、减少能源竞争成本、促进亚洲能源期货市场发展、增强区域经济联系等方面获得显著收益。同时,联合议价的经济成本比较小,国家安全成本和政治成本则在两国之间存在不对称性,并且难以量化。     

INVESTMENT RISK AND THE TRANSITION INTO HOMEOWNERSHIP*

ABSTRACT This paper investigates the extent to which house–price uncertainty affects the transition of renter households into homeownership. Using a 14‐year household panel from the Panel Study of Income Dynamics during the years 1984–1997 and measures of the time‐varying risk and return to owner‐occupied housing, we estimate a Cox proportional hazard model of the effect of house–price volatility on the transition into homeownership. Results indicate that house–price uncertainty has a negative and dramatic impact on transitions into homeownership. In addition, we find that the low‐wealth renters are particularly sensitive to house–price risk.     

A connectivity model as a potential tool for smart specialization strategies

The article contributes to the smart specialization literature by presenting a new approach, connectivity analysis, where Triple Helix (TH) relations (involving universities, companies and government) are at the centre of the entrepreneurial discovery process. Relations between helices may be seen, from the point of departure of proximity, as preconditions of connectivity, or interaction, measured through expectations and experiences. This offers potential solution to two limitations of proximity approach: its static nature and narrow focus on dyadic relationships. The connectivity analysis reveals the extent of mutual expectations, as well as tensions, or gaps. Based on this analysis, the article presents a policy model that is used to map structures of networks and gaps between TH actors. It may also identify strengths, weaknesses and problems. This analysis is used as input to structured dialogues between actors in leading positions in the TH and in smart specialization policy-making and implementation. This approach may lead to policy interventions supporting entrepreneurial discoveries. The model has been developed in partnership with researchers and the Regional Council of Ostrobothnia. The article also presents this case study and demonstrates the use of the connectivity model in practice.     

《管子·轻重篇》粮价考略

<管子·轻重篇>有不少战国秦汉时期粮价的记载,但很少有人重视.本文对<管子·轻重篇>所载的粮价进行了较系统的考证,将之与其它文献和考古资料互相比照,发现<管子·轻重篇>反映的粮价,无论是低价、平价还是高价,都与有关文献和简牍资料的记载基本一致.因此,本文作者认为<管子·轻重篇>所记载的物价是有重要研究价值的.     

城镇可持续生活供水价格研究--以陕西省关中地区为例

本分析了关中地区城镇生活水价现状和问题,得出了城镇生活水价是不可持续的结论,即水价低于供水生产成本,水价结构不合理。在探讨可持续水价的调整原则的基础上,提出了价格杠杆调节关中生活水价的措施,包括：逐步把水价调整到成本水价以上的水平,并调整水价结构,使之能反映供水成本和水资源价值;实行累进加价制度,对超定额用水征收高水价;实施季节性水价等。

乾隆初滇省代京铸钱失败原因浅析

文章通过对乾隆初年滇省代京铸钱之具体情况的考察,认为滇省代京铸钱是清政府为扭转铸钱严重亏损而采取的一项铸币政策。但滇省代京铸钱较之京局直接鼓铸反而增加了铸钱成本。实行滇省代京铸钱后,清政府铸钱开始盈利,但这并非滇省代京铸钱所致,而是清政府对云南铜矿实行垄断经营、压低铜价,即钱局使用滇铜鼓铸的结果。实际上,在使用滇铜为原料的前提下,京局直接鼓铸较之滇省代京铸钱更能节省成本,这是清政府停止滇省代京铸钱的基本原因。同时也说明清政府于乾隆初年实行滇省代京铸钱存在着决策性失误。
