| Open public data refers to the provision of data sets with originality and machine-readability by public management and service institutions for social utilization.Along with the implementation of the national big data strategy,releasing data dividends,breaking "data silos" and improving the level of national modern governance have become important consensus,and public data openness has become an important way for the country to accelerate the release of data value.While actively exploring the opening of data,various regions continue to formulate laws and regulations to provide institutional protection for data opening.With the advancement of public data legislation,many problems that restrict the further deepening of data opening have been exposed while achieving fruitful results.On the surface,the inconsistent provisions of core elements of public data and the unsoundness of related mechanisms are caused by the low legislative level of local legislators,but the deeper reason is that the current legal system of public data openness fails to generate institutional trust among data subjects,which makes it difficult to provide continuous institutional impetus for data openness practice.It is of theoretical and practical significance to use trust theory to study the openness of public data.We explore the causes and ways of institutional trust formation,build a credible institutional framework for public data openness based on the analysis of the logical structure and core elements of institutional trust,and improve institutional norms under the credible framework to inject institutional momentum for public data openness.Except for the introduction and concluding remarks,this paper is divided into four main parts:The first part mainly introduces the core concepts,characteristics and jurisprudential foundations related to public data openness.On this basis,it analyzes the coupling logic of public data openness and trust theory and the purpose to be achieved by solving the public data openness problem through trust theory,introduces the two trust dimensions of trustworthy legislation for public data openness,and studies the ways to improve data rules from the two dimensions.The second part focuses on analyzing the current state of public data openness legislation from the trust perspective.The theoretical controversies in the current state of legislation are introduced,and the problems in legislative practice are examined in the context of such controversies.The current state of legislation is examined from four different perspectives,and it is found that there are problems in practice,such as low legal rank,inconsistent provisions of core elements,lack of intrinsic trust mechanism and inadequate extrinsic trust mechanism.The third part attempts to build a credible institutional framework for public data openness by combining the logical structure and core elements of institutional trust formation,and to make useful reference to extraterritorial solutions.The logical structure of trust in public data opening system consists of three aspects: public data utilizers as trust subjects,data openers as trust carriers,and data opening system as trust objects.The normative awareness of data users,the normative behavior of data openers and the quality of open data influence the trustworthiness of the public data open system as the cognitive,behavioral and value elements of public data openness,respectively.In the fourth part,under the credible framework of public data openness,the credible norms of public data openness are refined and improved in four aspects:clarifying the legislative path and core elements of regulations,constructing the inner trust mechanism of public data openness and improving the outer trust mechanism. |
