在中国，中小型企业在促进市场竞争，提高市场的活力，特别是提供就业机会等方面发挥着不可替代的作用。据工业和信息化部的统计，中国目前的小型和中小型企业（包括微型企业，比如个体工商户）已达到约4200万个，占全国企业总数的99.8%。与此同时，这些中型和小型企业上缴的税收、提供的城镇就业岗位，以及所创造的产品与服务的价值，分别占我国的53%、75%、60%以上。为了充分调动我国这些中型和小型企业的积极性，我国先后颁布且实施了一系列政策和法规，力求通过政策法规将中型和小型企业纳入到政府采购的行为中，将支持中小微型企业的发展这一举措提升到国家战略层面的发展上来相关政策推行以来，受全球性经济增速趋缓、欧洲主权债务危机、国内经济增速回落等多方面影响，中小型企业发展空间逐步被压缩，参与中央和地方各级政府的采购活动的中小型企业所占整体的企业数量比例仍然很低，由中小型企业直接提供的产品和服务在中标金额中所占比例同样偏低，大量中小型企业仍面临生存困难，未能享受到国家相关的优惠政策。可以看出，通过政府采购的方式来支持中小型企业发展的政策效果并不好，也就是，通过政府采购的手段支持我国中型、小型企业的发展这一政策落空，其生存窘境仍未得到缓解。为此，如何更有效地发挥政府采购对中小型企业发展的推动作用，如何进一步完善政府采购的政策功能，将“好钢”用在“刀刃上”，就成了当下迫在眉睫的关键性问题。本篇文章将从政府采购工作的流程、环节切入，对政府采购扶持和推进中小型企业发展，特别是小微企业发展问题进行深层次的研究，从而提出一些包括搭建政府采购信息的大众化共享和公开平台、建立政府采购选取企业的科学标准方法以及增强政府采购目标与成果的考核等方面的建设性思考，供相关部门进行研究或完善。

In China, small and medium-sized enterprises play a great role in the market competition, in terms of giving the market more vitality, and making more employment opportunities. According to the statistics by the Ministry of Industry and Information Technology, there are more than 42 million small and medium sized enterprises in our country, making up 99.8% of the whole market. Products or services, taxes, and employment opportunities provided by small and medium sized enterprises are taking 60%, 53%, 75% share of the country respectively. In order to promote the productivity of small and medium-sized enterprises, China has published a series of laws and regulations, taking it to a national strategy level, that require governments make good use of the tools of government procurement to accelerate the stimulation on small and medium sized enterprises.Although the laws and regulations have been running for years, the development of small and medium-sized enterprises stall due to the global economics depression, the European sovereign debt crisis, and the slowdown of China’s economic growth. Small and medium-sized enterprises are not playing an expected role in the government procurements. Without the preferential of the laws and regulations, small and medium- sized enterprises are negatively affected by the depression. In this sense, laws and regulations on stimulation are not working properly. Accordingly, improving the functions of government procurements, making it more effective on stimulation of the development of small and medium- sized enterprises, is an urgent task.This thesis examines the process of government procurements, and factors that influence the policy implementation on the stimulation of small and medium sized enterprises with government procurements. The findings suggest a necessity to set up an internet-based information sharing center, to establish a standard evaluation system on government procurements, and make a more powerful regulation and supervision system for better policy implementation.
