我国农产品科技因素的国际竞争力分析

在目前条件下,农产品科技含量的高低决定了其农产品附加值的多少,而农产品附加值的多少则在某种程度上影响了国际竞争力的强弱。本文从农产品科技因素对我国农产品国际竞争力进行了分析,通过分析影响农产品科技因素的原因,提出了提升我国农产品科技水平的主要途径。

基于网络DEA交叉效率模型的我国商业银行效率评价研究

本文从商业银行的实际情况出发,将其经营过程划分为资金筹措与资金运营两个阶段。结合网络DEA与权重平衡交叉效率思想,并利用熵值法处理交叉效率的集结问题,构建了商业银行各子系统及链形系统的交叉效率评价模型。将上述模型应用于我国16家商业银行的效率评价,发现这16家商业银行的效率普遍不高,且城市商业银行的系统平均交叉效率高于国有银行,国有银行的系统平均交叉效率略高于股份制银行。

Effects of distribution channel structure in markets with vertically differentiated products

This study examines how the structure of distribution channels may influence firms’ quality and price strategies and how they may in turn affect consumer welfare. It treats product quality as a decision variable so that the degree of product substitution becomes endogenous rather than exogenous as in previous studies. We find that, with vertically differentiated firms, the changes in channel structure have asymmetric effects depending on whether they occur in the high-quality channel or in the low-quality channel. The product quality of the high-quality channel decreases when it decentralizes unilaterally. However, product quality of the low-quality channel would increase when it decentralizes. The high-quality manufacturer and its channel suffer more from decentralization in comparison with their low-quality counterparts, and the low-quality manufacturer actually receives greater profits when both channels are decentralized. An important driver behind these asymmetries is the interaction between firms’ pricing incentives in integrated versus decentralized channels and what consumer segments they serve. Our analysis indicates that decentralization may reduce consumer welfare, but decentralization in the high-quality channel hurts consumers more than that in the low-quality channel. Therefore in a competitive environment where firms make both quality and price decisions, channel integration would have significant welfare enhancement effects through the elimination of double marginalization, especially if it happens in the high-quality channel. Moreover, we demonstrate that once quality is endogenized, integration is the only equilibrium of channel structure choices. This suggests that the private incentives of firms may actually benefit consumers but do not have to be in line with the general preference of industry regulation for decentralization.
