Abstract

The paradigm of public administration has been through traditional public administration，new public management and new public service.Since the 20th century，the international community has been more concerned about the competitiveness of the government，the government's legitimacy and responsiveness，“less government，more governance”has become a common feature of western government reform.In this context，network governance theory came into being in response to the needs of society，and became an important paradigm of public affairs governance.The international community has been continuously paying attention to the quality and efficiency of public services，and been similar in the pattern of governance，cooperative networks become the basic pattern of foreign public services.Cooperative networks include intergovernmental and inter-regional internal cooperation networks，and also include the government，the market and the society external cooperation networks，to form the mechanism of“both inside and outside”and to realize effective supply of public services in an integrated，participated and interactive formation.In recent years，the Chinese government attaches particular importance to the construction of public services，but the current public service still exists supply shortage，supply imbalance and inefficient supply problems.The key lies in innovating the ways and methods of governance，and promoting interaction and cooperation between the government，the market and the society.The Third Plenary Session of the Eighteenth Central Committee of the CPC proposed“The overall goal of comprehensive deepening reform is to improve and develop the socialist system with Chinese characteristics，promoting national governance systems and modern governance.”Therefore，the network governance theory implied in the field of public service is in line with governance theory innovative trend，and in the needs of improving the efficiency of public service.

The book is based on network governance theory to discuss the public service optimization method and path，and according to the ideas of“construct theory-practice test-improve theory”to design the paper frame.Firstly，solidify the basis and premise for research.On the basis of literature review of both home and abroad，the author define the core concepts and related theories.Secondly，establish the core and focus of the research.Construct the theoretical framework of public service network governance，covering models，factors，evaluation mechanism and efficiency analysis.Again，return to practice test and demonstration.Compare the domestic and foreign cases of public service networks，and analyze of the shortages and gaps in our cases，and summarize the experiences of foreign cases.Finally，realizes in-depth study and sublimation.Improve the public service network governance theory，explain the measures and the future path of public service network governance，in order to be able to cope with risks and challenges of public service network governance，and to optimize the policy system of public service network governance.

The main content and the research conclusion of the book is divided into the following five parts：

The first is to define the concept of network governance of public service.The network governance of public service refers to a new governance pattern through a public-private partnerships，and multi-agents in the provision of public services including profit organizations and non-profit organizations.Government，market，society and the citizens form a win-win cooperative public services network on one or more public service programs，they share the common responsibility，the public power and public service affairs in an open，equitable and orderly public environment and truly realize risk and profit sharing goals.

The second is to build the theoretical basis of public service network governance.Based on domestic and foreign research literature，this paper analyzes the relevant theoretical basis and practical conditions of public service network governance，and lays the premise and foundation of the research.Theoretical basis include multi-center governance theory，consultative democracy theory，social capital theory，policy network theory and new public service theory； The practical conditions include“meta-governance”，cooperation mechanism，trust mechanism，responsibility mechanism and supervision mechanism.

The third is to build the public service network governance models and to evaluate the efficiency.？According to the different levels of government intervention，the public service network governance tools can be divided into a mandatory tool，market tools，social tools and mixing tools，the market and social tools have a more frequent use.The structure of network governance model of public service has experienced from the center of agglomeration to dispersed agglomeration development process.Network governance model elements which are also main participants of public service，including the government，market，society and citizens，existing mutual competition and game mechanism.Network governance of public service models in accordance with the characteristics of public service can be divided into the government dominant，market dominant，and society dominant public service network governance models.The influence factors of public service network governance is the precondition for the efficiency evaluation，including service project factors，internal factors and external factors.？Efficiency analysis of public service network governance，illustrates from the theory effectiveness，tool effectiveness，model effectiveness to output effectiveness.

The fourth is comparative study of network governance at home and abroad.Selection of cases focus on homogeneity and comparability，respectively，on behalf of the government leading，market leading，social dominance of the public service network governance model.Foreign selections are public security service network and child care service network case in America，as well as public housing service network in South Korea； Domestic selections are public security service network and public housing service network case in Beijing，as well as China's first home endowment service network in Nanjing Gu Lou community.The analysis shows that there is a certain gap between home and abroad in governance experiences，market and citizen society maturity and cooperation stability.

Last but the least is to improve the path of public service network governance.Current risks and challenges of public service network governance，including some scholar's doubts and mistrust of the theory and practice on public service network governance，as well as building issues，operating problems and outcome problems in public service network.Public service network governance main problems focuse on the fairness and transparency problems of network，the communication and responsiveness problems，the role of the main partners，the distribution issues sources of funding and income，and also performance assessment and regulatory issues.Then analyze network governance paths and put forward correspondence solutions of public service，from the target level，organization level，execution level and the safeguard level.Establish public service network governance concepts of fairness，efficiency，response and transparency.Clear and definite the meta-governance role of the government，the basic role of the market and the dominant role of the society.Improve governance tools，income distribution system and performance appraisal system in order to optimize the process of public service network governance.Provide support on talents，capital，policy，and protection in the regulatory mechanism，in order to promote the improvement and development of public service network governance.
