International Comparisons of Australia's Infrastructure Performance

International benchmarking has played a key role in the reform of Australia's infrastructure industries by promoting indirect or yardstick competition, in highlighting the need for further reform and building a consensus for implementing necessary changes. The international benchmarking of infrastructure performance by the Bureau of Industry Economics (BIE) between 1991 and 1996 did much to focus attention on the need for change. The BIE examined the performance of eight infrastructure industries relative to international best practice: electricity, rail freight, telecommunications, the waterfront, road freight, coastal shipping, aviation and gas supply. Performance comparisons concentrated on indicators of price, service quality, labour productivity and capital productivity. This paper reviews and summarises the performance comparisons the BIE undertook over the last three years of its infrastructure benchmarking program. The BIE international benchmarking program provides a useful role model for other countries wanting to seriously pursue reform of their infrastructure industries.     

中国股市对经济增长作用的实证检验

关于金融体系和经济增长之间关系的争论由来已久。本文在分析国外关于这一争论的研究成果的基础上,对中国的股票市场发展与经济增长之间的关系做了一系列实证检验,考察了金融体系的一个组成部分———股票市场与经济增长的关系。检验结果说明,中国股市发展与经济增长之间的相关性不高,回归结果也不能说明中国股市发展会推动经济增长。     

含价格折扣、允许缺货的两级供应链库存模型

研究一个供应商、多个销售商组成的两级供应链库存系统,针对具有价格弹性的市场需求、含有价格折扣、允许供应商和销售商产生缺货以及满足供应商和销售商Pareto有效性的情况,建立了使供应链系统整体盈利最大的存贮模型。并结合算例分析了价格弹性因子对系统盈利水平的影响。     

对企业技术创新自我实现的经济学分析

本文从经济学的理论角度分析了企业技术创新自我实现的可能性。分析发现：产品被成熟生产后的产量与资本报酬和资本边际生产率的大小有直接关系。因此，企业发展内部本身就可以通过市场供需调节来实现创新的循环和延续。从这一点上说，国家对于企业技术创新的鼓励政策应该更加依靠市场机制的作用。     

城市土地价格波动对房地产业的影响——1999～2005年中国20城市的实证分析

本文利用1999～2005年间的数据对我国地价与房价的关系进行了实证研究.研究结果表明房价对地价有显著影响,地价对房价的影响度较小.在对地价与房价互动传导机制进行研究时,提出了3个传导路径,这些路径上的各个变量大都相互影响.通过分析我们还发现金融支持和土地政策在地价与房价变动中扮演着重要角色,抑制房价不能只控制土地价格,还应从金融支持、投资等方面着手,制定更严格的信贷制度,增加房地产交易税和提高居民可支配收入.本文的研究对于政府制定正确的货币政策和房地产业政策具有积极的参考意义.     

中国证券市场价格波动与宏观经济协同性的实证研究

理论上，证券市场常被称为国民经济的“晴雨表”。本文选取工业增加值、广义货币供应量（M2）、消费者景气指数和国房景气指数等宏观经济指标，深入考察了宏观经济与沪深两市股价走势之间的关系。结果表明，在样本期内股价指数波动与宏观经济变量之间不存在协整性特征，中国证券市场与国民经济之间尚未呈现出稳定的长期均衡关系，证券市场并未发挥“国民经济晴雨表”的功能。这也表明，中国证券市场的宏观协调效率还有待于进一步提高。     

Theory Analysis of Model for Price Fluctuations in a Single Commodity Market

The price model for a single commodity market is a very important economic model that describes the basic rules for price fluctuations in a single commodity market. In this paper, we investigated the general case for the model, and proved that every positive solution is bounded and we obtained a necessary and sufficient condition for oscillation of every positive solution concerning positive state solution.

基于模糊评判分类控制法的流程式企业备件库存

从流程式企业备件备品库存管理的视角，利用模糊评判的方法对库存物资进行多标准的ABC分析，选择具有实际意义且有较强分辨性和代表性的统计指标，克服了传统库存分类法的片面性和局限性，对不同的库存备件相对于管理的重要性强弱作出明确的排序．得出具有实际经济意义的分类方案，同时根据最优分类结果，针对流程式企业库存物资的特性，着重考查在实际库存管理中存在的不合理之处，并对其进行更改。实行重点管理。     

The price relationship between organic and non-organic vegetables in the U.S.: evidence from Nielsen scanner data

This study investigates price relationships between organic and conventional carrots, tomatoes, and lettuce in the U.S. utilizing Nielsen scanner data from 2006–2015. We employ a threshold vector error correction model (TVECM), threshold vector autoregressive model (TVAR), and threshold cointegration test to test whether market integration exists between organic and conventional vegetables as well as the existence of asymmetric price transmission. The results find positive long-run relationships between organic and conventional prices of carrots and tomatoes and show the existence of asymmetric price transmission in price pairs of lettuce and tomatoes. Our findings suggest that the price relationship between organic and conventional vegetables varies by characteristics, such as shelf life, volatility in the price premium, and substitutability.
