近来我国高科技中小企业迅速发展，其发挥的作用在我国经济越来越明显。为帮助高科技中小企业建立更多的融资渠道，我国中小企业板和创业板先后建立和完善，不仅帮助了这些企业利用融资取得资金或度过财务危机，而且一定程度缓解了就业压力。虽然高科技中小企业具有无可比拟的优势和较好的发展势头，但由于我国金融发展水平较低，金融市场不完善，同时企业也具有缺乏核心竞争力及管理上的问题，导致面临着融资难及融资结构不合理的困境，严重阻碍了其成长，限制了国民经济的增长。在融资当中，中小企业采用不同的融资手段获取资本，由于手段、途径、时间上存在差异，不同的融资结构就会导致不同的融资成本。所以，中小企业应该采取何种融资方式，以及应该如何安排公司的融资，从而使得其健康、迅速的成长仍是需要探讨的问题。本文以融资结构理论为指导。首先，通过高科技中小企业融资行为与偏好，分析不同融资结构对企业成长的影响；其次，根据高科技中小企业融资行为，辨析高科技中小企业融资现状和存在的问题和隐患。最后，得出融资结构不合理成因，并分别从政府、企业的角度，给出我国民营企业融资结构优化的建议。
