【摘要】 中小企业在经济和社会发展中起着不可替代的作用,科技型中小企业更是在科技进步和经济发展起着拉动的作用。而融资约束是制约科技型中小企业发展的一个突出因素,同时也是学术界研究的热点。因此,解决科技型中小企业融资约束问题具有重大的理论和现实意义。本文以中小企业发展理论、企业生命周期理论、公共物品理论和政府管制经济学等为理论基础,通过对天津市科技型中小企业的调查数据进行实证研究和理论分析,对科技型中小企业融资约束成因进行分析,并侧重从政府和担保的角度提出对策措施。本文首先对中小企业和科技型中小企业的特点进行了总结归纳,进而提出了科技型中小企业的技术经济特点和融资特点。然后在对天津市科技型中小企业发展情况和融资情况进行调研的基础上,以天津市中小企业为例通过实证分析,研究了位于不同生命周期的科技型中小企业的融资结构特征,以及影响科技型中小企业融资结构的影响因素。并且通过对调研数据的分析,研究中小企业融资的现实情况,研究中小企业融资难的现实表现及成因,为理论分析提供数据支撑。在理论和实证基础上,本文运用系统观点,对科技型中小企业融资约束的微观和宏观影响因素进行探析,特别是运用微观经济学和系统分析的观点,建立了分析中小企业融资约束的三层次系统分析模型,从银企资金供求、市场结构以及政府行为和外部环境等三个层次,分别分析中小企业融资约束的成因,并重点对政府和担保的作用进行了分析。通过以上分析框架,从理论高度找出了目前科技型中小企业融资约束面临的主要问题。本文针对科技型中小企业融资约束面临的主要问题,结合天津实际,探索提出科技型中小企业不同生命阶段的融资组合方式。依托制度经济学观点,提出政府部门在中小企业融资系统中应发挥的作用和采取的措施。充分肯定中小企业信用担保在解决融资难中的重要作用,建议政府部门继续发挥在担保体系构建中的牵头带动作用。结合集群理论,建议政府部门,建设园区和楼宇等相关企业集群,并以集群融资方式,解决融资难问题。更多还原
