abstract: 当前各个城市都在努力推动“互联网+政务”的公共服务新模式，打造政府公共服务平台，提供“一站式”的服务资源，以民众需求为中心，解决民众信息查询、政府办事预约、政策咨询等公共活动的需要。可以看出，政务平台给民众的生活带来极大的便利，是当前各地政府响应中央建立“智慧城市”“数字中国”的重要举措。 本课题发现当前的政务平台逐步引入PPP模式，借助社会资源开发政务平台。但是，PPP模式是否有利于政务平台的建设，受到哪些因素的制约，如何更好地利用PPP模式进行开发工作，这些问题在现前的研究中没有得到很好地探索。带着这些问题，本课题对PPP模式在政务平台建设中的作用进行了深入剖析。主要研究内容如下： 在第一部分中，本课题政府公共服务和政务相关理论进行了全面整理，发现政务平台要想走出一条健康发展之路，需要借助社会资源进行市场化，而PPP模式符合当前政务平台建设的需要。本文对PPP模式在国内外电子政务的应用进行了分析，提出了本文的研究主题。 在第二部分中，本文对华东地区50座城市的政务平台进行了调研，对常见问题进行了整理，发现PPP模式已经广泛应用于政务平台建设中，且主要有四种模式，本文对50座城市的政务平台建设情况进行了数据采集，并进行了深入分析。 在第三部分中，结合调研现状和文献研究成果，提出了PPP模式影响政务平台建设的相关假设，并构建了计量模型。通过短面板分析验证假设，并进行了Robust分析，证实结论的普适性。 在第四部分中，本文分析了研究结果，认为政务平台采用PPP模式能够有效促进政务平台的建设水平，提高用户满意度；并且PPP模式与合作企业的估摸、信息的透明程度和平台的交互能力存在显著的交互作用，共同影响用户对政务平台的评价。政府引入PPP模式，充分对接可利用资源，并加强盈利控制，对当前政务平台的建设是具有积极意义的。 / Dissertation/Thesis / Doctoral Dissertation Business Administration 2019

The introduction of PPPs in infrastructure provision has changed the way in which governments around the world now view infrastructure provision. However, the introduction of PPPs to deliver the needed infrastructure has benefited only a few companies. Most of these companies are the big construction firms that possess technological know-how and those that have the financial ability to execute large infrastructure projects. Although SMEs are important for employment creation, inequality and poverty reduction, the participation of SMEs in these PPP projects is very low. This is because PPP models in developing countries are based on those used in developed economies, and such models ignore the socio-economic problems facing developing countries. Therefore, this study argues that PPP projects in developing countries present an opportunity for growing the SME sectors in developing countries. It challenges the viewpoint of seeing infrastructure backlogs only as providing opportunities to big private sector companies and argues that infrastructure backlogs can be used by governments to reduce the triple challenges of unemployment, poverty and inequality by linking SMEs to PPP projects. The traditional PPP model that is being applied by many developing countries does not fully encourage the participation of SMEs in PPP projects, as most of the projects executed through this model are bundled into big projects that SMEs cannot execute due to a lack of technological know-how and weak balance sheets. The study therefore suggests different ways in which the participation of SMEs in PPP projects could be improved based on the results of the survey conducted for this study. The study then proposes an “innovative conceptual PPP model for sustainable SME development” that takes into account the needs for developing countries to create jobs, reduce poverty and inequality. It also takes into account all challenges for SMEs identified through the review of literature and the study survey. / Economics / D. Litt. et Phil. (Economics)
