规范会计理论与实证会计理论哲学比较

规范会计理论以会计假设为逻辑起点,经过严密的逻辑推理形成一套关于会计“应该是什么”的知识体系,实证会计理论人实际会计行为出发,应用“成本－效益”原则建立各种会计模型,规范会计理论的前提缺乏可验证性,只能神为科学“假说”,而实证会计应用科学方法进行个案研究验证,结论往往受到资料的真实性,代表性和选择资料的倾向性影响,即使正确,也难以形成理论体系。     

基于波特钻石模型的中国汽车金融产业竞争力分析

本文以汽车金融为独立金融产业,在波特钻石模型基础上引入金融竞争力若干指标,对我国汽车金融产业的生产要素、国内需求、支持性产业和相关产业、公司结构、战略和竞争分析进行分析。研究发现我国汽车金融产业竞争力存在复合型汽车金融人才匮乏、资金来源限制多、消费征信制度缺失、汽车信贷产品单一、市场开发不够,产业集中度低等问题。最后从产业政策、法律制度与监督管理三方面提出了汽车金融产业竞争力的提升对策。     

Nonparametric fixed effects model for panel data with locally stationary regressors

We develop methods for inference in nonparametric time-varying fixed effects panel data models that allow for locally stationary regressors and for the time series length $T$ and cross-section size $N$ both being large. We first develop a pooled nonparametric profile least squares dummy variable approach to estimate the nonparametric function, and establish the optimal convergence rate and asymptotic normality of the resultant estimator. We then propose a test statistic to check whether the bivariate nonparametric function is time-varying or the time effect is separable, and derive the asymptotic distribution of the proposed test statistic. We present several simulated examples and two real data analyses to illustrate the finite sample performance of the proposed methods.     

中国地区工业绿色全要素生产率增长:——基于方向性距离函数的经验分析

结合方向性距离函数和跨期数据包络分析法,测度绿色全要素生产率增长时尽可能地避免了出现技术倒退结论。中国省份工业的经验分析表明:忽略非期望产出的全要素生产率增长被高估,并混淆了技术进步和技术效率变化的相对贡献;技术无效率普遍存在且省际差异和年际波动性大,但这与经济发展水平无关;绿色全要素生产率变化也存在省际差异和年际波动特点,其中技术进步是其增长的主要源泉,而技术效率恶化是其倒退的根本原因;绿色全要素生产率增长存在明显的倒U型趋势和趋同性,而且外资利用印证了"污染天堂"假说。     

Real Exchange Rate in China：A Long-run Perspective

This paper investigates the RMB exchange rate from a long‐run viewpoint. Whether China's rapid economic growth brought about real exchange rate appreciation between 1975 and 2002 is empirically examined, based on a supply‐side model, the Balassa—Semuelson Hypothesis (BSH). The same test is conducted on Japan, Hong Kong, Korea, Malaysia, Singapore, Thailand, the Philippines, Indonesia and India. Our result indicates that the BSH only exists where the industrial structure has been upgraded and the economy has been successfully transformed from an agricultural economy to a manufacturing economy. Interestingly, China, among those where the BSH does not present, appears to be upgrading its industrial and trade structure. We then try to answer the question of why past rapid growth has no significant relationship with the RMB real exchange rate and what factors are underlying the trend of the RMB real exchange rate. We expect an appreciating trend of RMB real exchange rate in the foreseeable future, presuming that China's industrial upgrading process continues and the factors pertaining to the BSH's prediction, such as rise of wage rates in both tradables and nontradables, become more significant.

产业内贸易对劳动力市场调整的影响分析——基于中国制造业面板数据的SAH检验

随着中国经济全球化进程的深化,外贸对国内经济的影响日益显著。根据平滑调整假说(SAH),劳动力市场调整成本会随着产业内贸易水平的提高而降低。基于中国制造业22个细分行业面板数据进行检验,本文发现间隔3年的边际内产业指数最为有效,且产业内贸易水平对劳动力市场调整具有滞后效应,但回归分析结果并不支持SAH。随着产业内贸易比例扩大,劳动力的产业间调整增加,而并非产业内的调整。此外,劳动生产率和国内显性需求对劳动力市场调整有很大影响,在产业内贸易水平较高的行业内,劳动生产率的这种影响更加显著,而显性需求和产业内贸易水平影响作用较弱。     

A critique of Porter＇s cost leadership and differentiation strategies

Porter identifies high market share with cost leadership, citing GM as a successful practitioner of this strategy. However, GM became a market share leader in the American automobile industry due to a strategy of market segmentation, differentiation and a broad scope shaped during the 1920s. Porter argues that cost leadership and differentiation offer an equally viable path to competitive success. Nevertheless, a differentiation strategy based on superior quality compared to competition is more profitable than cost leadership strategy. It can lead a business to become a market share leader, and consequently even a low-cost leader. Research indicates that differentiation and cost leadership can co-exist. However, Porter insists that each generic strategy requires a different culture and a totally different philosophy. The problem is that Porter＇s generic strategies are too broad. It is not his logic that is flawed, but his basic premise that prescribes cost leadership strategy as the only route to market share leadership, and presents a narrow view of differentiation with a unique product--sold at a premium price--on the one hand, and a ＂standard, or no-frills＂ product on the other. Mintzburg （1988） says Porter＇s cost leadership strategy should be called ＂price differentiation＂： a strategy that is based on a lower price than that of the competition. He suggests that business strategy has two dimensions： differentiation and scope. Thus, setting scope aside, competitive strategy has only one component： differentiation. So, the key question is not whether to differentiate, but how？ First, make customer-perceived quality as the foundation of competitive strategy because it is far more critical to long-term success than any other factor. Second, serve the middle class by competing in the mid-price segment, offering better quality than the competition at a somewhat higher price. It is this path that can lead to market share leadership--a strategy that can be both profitable--and sustainable.

一种基于族类划分理论的保险营销信息获取方式研究

保险营销中的传统信息获取模式存在弊端，本文提出一种假说，利用历史资料推断客户的保险购买模式，从而获得客户更加完整的购买信息。这首先需要对商品进行族类划分。本文探讨了一种创新型的商品族类划分的基本理论以及操作方法，并对其方法进行了部分检验。
