Abstract: The deposit insurance fund system is one of the important forms of constructing the government financial safety net, which plays an important role in the prevention of bank run crisis. The effective operation of the deposit insurance fund system is inseparable from the setting of the premium scale that meets the risk characteristics and compensation distribution. In order to clarify the structural change and influence effect of the fund size, the AD-AS fund size research model was built by referring to Keynes theory to explain the relevant variables affecting the change of the deposit insurance fund size. The results of the model showed that: Marginal insurance propensity and marginal expenditure propensity have different effects on the change of the scale of the double cycle. The existence of spillover effect makes some variables have negative relationship with target variables. Through normative analysis, suggestions can be provided for the adjustment of fund operation policies, so as to improve the precision and pertinence of macro-control policies.#@#@#摘要: 存款保险基金制度是构建政府金融安全网的重要形式之一，在预防银行业挤兑危机中发挥着重要作用，而存款保险基金制度的有效运行，离不开设置满足风险特征与赔付分布的保费规模。为厘清基金规模的结构变化与影响效应，通过参考Keynes理论思想构建AD-AS基金规模研究模型，解释影响存款保险基金规模变动的相关变量。模型结果表明：边际保险倾向与边际支出倾向对双周期规模变动产生不同的影响效应，溢出效应的存在使部分变量与目标量产生负向关系，通过规范分析可以为基金运营政策调整提供建议，从而提高宏观调控政策的精确度与针对性。
摘要：
Urban clusters are important carriers for cities to participate in international competition and cooperation, and a booster for urban sustainable development. This study measured the degree of urban clusters by utilizing the panel data of 278 cities in China during 2004-2016. Then, an extended meta-frontier data envelopment analysis (EM-DEA) model was applied to estimate the total-factor ecological performance (UTEP) and decompose it into two sub-index from the perspective of "resource conservation" and "environmental friendliness". On these bases, we employed a dynamic panel data approach to examine and demonstrate the relationship between urban cluster and UTEP in two dimensions, and further explored transmission channels of urban clusters on UTEP by adding the mediating effect. The results show that resource conservation increases first and then decreases with the increasing of urban clustering level, while environmental friendliness showed the opposite trend, making the latter become the main way for urban clusters to improve the UTEP. Industrial structure supererogation and rationalization are transmission channels for environmental friendliness rather than resource conservation in the way of improvement of UTEP. Technology innovation, as well as technology diffusion, also improves UTEP to some extent. In addition, urban clusters in eastern and central China have the greatest improvement in UTEP, while such effects are not the case in western China. Urban clusters in the second half sample period are more conducive to the improvement of the UTEP, with these potentially being the gains from the improvement of the level and quality of urban clusters.
