中小企业融资与发展中小金融机构 总被引:1,自引:0,他引:1
李军农 《武汉市经济管理干部学院学报》2003,17(1):23-26
一个国家的经济稳定持续增长离不开数量众多的中小企业,特别是在稳定经济、吸纳就业、出口创汇和提供社会服务等方面,中小企业的作用是不可或缺的。我国中小企业的发展状况与美国相比,相距甚远,研究美国中小企业的融资模式对解决我国现存的中小企业融资困境具有一定的参考价值。本文就中小企业融资与发展中小金融机构提高了我国相应的几点建议与对策。 相似文献

Food stamp recipients may lack access to larger stores, reducing the availability of nutritious food. Reliance on smaller stores may have undesirable impacts. Policy alternatives include limiting food stamp redemption to larger stores and subsidizing store development. I estimate that limiting redemption to supermarkets and grocery stores, or supermarkets alone, results in losses ranging from $499.2 million to $1.05 billion, or $1.17 billion to $2.44 billion (respectively) annual loss in food stamp recipient welfare nationwide. The impact of improving access is also significant, ranging from $333.6 million to $931.2 million. 相似文献

网络营销的创新性质包括创新程度和创新效益两个方面。创新程度反映网络营销创新的影响力度,是过程性指标;创新效益反映网络营销的经济效应,是结果性指标。将创新度和效益度垂直相交构成一个二维平面,并将其分别划分为高低两个级别段,可形成四个定位模块,即触网型创新、网络实验型创新、网络营销专家和运营网络型创新。一般情况下,企业网络营销创新往往从触网型创新出发。进而上升到运营网络型创新阶段,但在网络营销实践中,某些创新运动并不是严格地起于触网型创新,而止于运营网络模型,更有逆向运行的情况存在。 相似文献

In this paper a multi-factor generalization of Ho–Lee model is proposed. In sharp contrast to the classical Ho–Lee, this generalization
allows for those movements other than parallel shifts, while it still is described by a recombining tree, and is a process
with stationary independent increments to be compatible with principal component analysis. Based on the model, generalizations
of duration-based hedging are proposed. A continuous-time limit of the model is also discussed.

The study examines the relative ability of various models to forecast daily stock index futures volatility. The forecasting models that are employed range from naïve models to the relatively complex ARCH-class models. It is found that among linear models of stock index futures volatility, the autoregressive model ranks first using the RMSE and MAPE criteria. We also examine three nonlinear models. These models are GARCH-M, EGARCH, and ESTAR. We find that nonlinear GARCH models dominate linear models utilizing the RMSE and the MAPE error statistics and EGARCH appears to be the best model for forecasting stock index futures price volatility. 相似文献

The main objective of the present study is to examine empirically the long-run relation of broad money demand and its determinants in Japan. In contrast with previous study, the present study considers various components of final expenditure demand as determinants that are final consumption goods, expenditure on investment goods and exports. Using quarterly data over the period 1973Q1–2000Q2, the results of the bounds test [J. Appl. Econ. 16 (2001) 289] indicate a stable long-run relationship between demand of real M2 and its determinants. The empirical results also highlight that different domestic demand components yields different effects on Japanese broad money demand behavior. The estimated unrestricted error-correction model appears to track the data well and the results have important policy implications. 相似文献
