With the advancement of technology and development of society， “public governance reform driven by big data” has become a hot topic for public management scholars. Since 2013， the first year of big data recognized by the academia， the domestic academia has exported a large amount of research on “public governance reform driven by big data”. Now it is time for a scientific evaluation and review to respond to new demands on theoretical research by the practice of “public governance reform driven by big data”. Using CiteSpace visual analysis software， we conduct a quantitative analysis on literature concerning “public governance reform driven by big data” in the 2013-2020 China Academic Journals Network Publishing Library （CNKI） CSSCI journals and the Chinese Core Journal Sources， and find that hotspots in this research field mainly focus on governance paradigms， technological rationality， value rationality； in terms of the main thread of research， while the research enthusiasm for related topics such as “e-government， cloud computing， and government networks” is decreasing， the enthusiasm for such topics as “path， targeted poverty alleviation， and open government data is increasing”. We also find that research on “big data-driven-public governance reform” as a whole shows the characteristics of returning to humanism in research theme， pursuing pragmatism in research content， and moving towards the “fourth paradigm” in research methods. In the future， the research on “big data-driven-public governance reform” will focus more on technology in research content and pay more attention to social reality in research theme.

 

The 20th National Congress of the CPC referred to “self-reform” as “the second answer” to the question of escaping the historical cycle of rise and fall of the Party， and stressed that “We must persevere with full and rigorous self-governance， continue to advance the great new project of Party building in the new era， and use our own transformation to steer social transformation.?” “Using our own transformation to steer social transformation” is another important theoretical innovation made by the Party since the 18th National Congress. ?The proposition is a continuation and development of Marxist revolutionary thought， a summary of the experience of a century of endeavor of the Communist Party of China， and an inevitable choice for realizing national rejuvenation. A careful study of the theoretical， historical and practical logic is helpful to deeply understand the significance of steering social transformation via self-reform of the Communist Party of China.

The “Two Establishment” is a major political achievement of the Party in the new era， with profound theoretical， historical and practical logic. It is an organic whole that cannot be separated from each other. The essence of “two establishment” is about the core of the Party’s leadership and its guiding ideology， and the core of the Party’s leadership and the main contributors of the Party’s guiding ideology are highly unified， which is the essential characteristics and political advantage of the CPC. A deep understanding of the decisive role of the “two establishment” is of vital significance to advancing the great new project of Party building in the new era and the realization of the great rejuvenation of the Chinese nation.

Adhering to theoretical innovation is an important historical experience accumulated by the Chinese Communist Party over the past century. In the new era， the CPC’s adherence to and promotion of theoretical innovation are endowed with significant advantages and strategic opportunities， that is， theoretical characteristics of Marxism， the solid foundation for the Sinicization of Marxism， the urgent call for the great practice at home and abroad， and the overall favorable international environment. At the same time， it is also facing practical challenges like the turbulent international environment， the world’s scientific and technological and cultural progress， the arduous task of domestic reform and development， and the self-improvement of the Party. To promote theoretical innovation in the new era， we must follow the practical path of learning from the experience and lessons of theoretical innovation in the past century， carrying forward the theoretical trait of advancing with the times， and enhancing the practical ability of the whole Party in theoretical innovation.

In view of the overall situation of the cause of socialism with Chinese characteristics， and from the height of realizing the great rejuvenation of the Chinese nation， Xi Jinping Thought on Culture， by focusing on the specific reality of China’s cultural construction and adapting to the new requirements of cultural development， provides a systematic and in-depth explanation on the construction of China’s socialist culture in the new era， points out the overall objectives and tasks of cultural construction in the new era， and clarifies the status and role of cultural construction， as well as the fundamental policies and strategic measures， thus making another major innovation on the Theory of Chinese Socialist Culture Construction in the new era.

Strengthening the political guidance over youth is an inevitable requirement for fostering socialist builders and successors， and is also a primary task to inspire the youth to shoulder the mission of national rejuvenation as a new generation of young people in the new era. Over the course of the past 75 years since the founding of New China， the political guidance over youth of the CPC has gone through three stages of development： the period of socialist revolution and reconstruction， reform and opening up and the new period of socialist modernization， and a new era of socialism with Chinese characteristics. The CPC has accumulated rich experience in its political guidance over youth for over 70 years， that is， adhering to the CPC’s leadership of the political guidance over youth， starting from the perspective of youth characteristics by respecting the laws of youth growth and giving full play to the role of youth organizations led by the Communist Youth League of China. In the new era， in strengthening political guidance over youth and cultivating new generations in the new era， we should attach importance to the youth and guide the youth from the strategic height； we should respect the dominant position of youth and give play to the role of young people as a fresh force； we should cultivate the spirit of struggle in youth and encourage young people to persist in struggle and pursue their goals relentlessly； we should give play to the leading role of the Communist Youth League of China to better unite， organize and mobilize young people.

Based on the cross-system digital transformation theory， this paper explores the process mechanism of adaptive change of digital management from the perspective of management mode transformation with the case study of ByteDance. The results show that ByteDance achieves its management mode transformation from Key Performance Indicator （KPI） to Objectives to Key Results （OKR） through the construction of innovative culture， the design of self-driven organization， and the application of technological coordinative platform. Therefore， this paper proposes a process model of adaptive change of digital management from the perspective of management mode transformation， that is， via innovative enterprise culture， self-driven organizational structure and coordinative technology platform， enterprises are propelled to transform from hierarchical management mode to grid management mode， and establish a management mode that adapts to the digital economy environment. This research provides contextual explanation on the process mechanism of the cross-system digital transformation， and offers practical implications for enterprises to establish a highly adaptable management mode to the rapidly changing market environment， user needs and employees within the enterprise.

With the rapid growth of the Internet in China， the “information cocoon” has emerged in the Internet context of China， and has had an impact on the distribution and proliferation of mainstream ideology. The condition for “information cocoon”， from the perspective of its generation and development， is the “echo chamber effect”， that is， the repeated dissemination of homogenized information. When the audience is trapped in the homogenized information， it leads to the formation of the “information cocoon”， which may cause “group polarization”. The “information cocoon” may block the dissemination of mainstream ideology in the community， create conditions for the dissemination of wrong ideas and negative information in the group， and in extreme cases may even lead to fanatical online public opinion events. Thus， to reduce the negative effect of “information cocoon” on the dissemination of mainstream ideology， it is necessary to rouse netizens' civic awareness from the ideological level to eliminate the barriers of “information cocoon” as much as possible， carry out various ideological publicity for different types of “cocoon” from the cultural level， and build network supervision agencies from the legal level so as to ensure the timely supervision of information in emergency cases.

Logistics industry， while making great contributions to economic and social development， has caused problems such as energy and land consumption and large-scale discharge of “the three wastes” （waste gas； waste water； industrial residue）. The implementation of green behavior by logistics enterprise can reduce environmental pollution and resource consumption. Is it due to the continuous improvement of green standards or the desire for green performance that logistics enterprises are implementing green behavior？ What is the relationship among green standards， green behavior and green performance？ Through empirical studies on 745 logistics enterprises， the results show the following findings： green standard plays a positive impact on promoting green behavior， and the role of market standard is greater than that of government standard； green standards have a positive impact on green performance and green behavior has a mediating effect between them. Institutional quality plays a positive moderating role between green standard and green behavior， and the moderating effect shows regional differences. Therefore， China should accelerate the construction of logistics standard supply mechanism by both government and market， strengthen the system design and execution of government， and promote the improvement of green performance effect of green standard.
