To study the history of the Communist Party of China, we should first seize the theme and thread of her centennial history, in a way that we can grasp the essence of history. The theme here, this paper points out, is “the Party’s having been seeking happiness for the Chinese people, rejuvenation for the Chinese nation,and great harmony for the world”. The thread here, this paper tells, refers to“her unremitting efforts for practicing the aspiration and the mission, her continuous struggle for theoretical innovation and creation for adopting Marxism to the Chinese context, and her non-stop pursuit of strengthening self construction to maintain the advanced nature and purity since her founding in 1921. Both the theme and thread can be caught only by focusing on the overall historical situation of the Party in the past 100 years.

As food safety is directly related to people's safety and health, in its supervision risk control should be taken as the first priority. With risk governance’s having been widely used in all kinds of risk prevention and control, how to accurately position the risk governance function of food safety sampling inspection and to further perfect the inspection process so as to optimize its function is worth studying. Future sampling inspection in China, the previous literature, and 50 typical cases and practice progress of sampling inspection in 2017 tell, should enhance the mechanism of central-local linkage and political-social interaction on the basis of risk monitoring and disposal, and refine the process and optimize the function in terms of adopting multi-source risk information, taking advantage of complementary monitoring network, enhancing risk identification, improving risk communication, and enhancing risk tracking.

As the innovation of government affairs, in the digital society, bears the characteristics of timeliness and replicability, an exploration of the diffusion mechanism of government affairs innovation, is of help to render a wide use of the innovation and enhance governance ability. This paper takes the promotion and use of WeChat official accounts of 31 provincial departments on food and drug administration as the study case and adopts the internal and external models of innovation diffusion for case analysis. The results tell that 1) inter-governmental competition plays a key role in the innovation of official WeChat of that sort in the same province; 2) the informatization of the enterprises within the jurisdiction serves as a driving force for the WeChat innovation; 3) the government’s own network service brings about independent policy innovation when the external environmental impact is low.

Inter-governmental cooperation,serving as an important phenomenon in the public administration in China, has changed, to a certain extent,the competition oriented relationship between local governments. Two local governments with different performance objectives but a common target to achieve a win-win results on food safety and poverty alleviation, cooperate with models, such as comprehensive cooperation, information-based cooperation, entity-based cooperation and consumption cooperation, different in degree of food supervision based on different combinations of supervisors and supervision tools.This paper, based on the analysis of “cost-benefit”, finds that the historical cooperative relationship and the real financial connection produce the direct and indirect costs of cooperation, while the acquisition of the model title and the occurrence of negative events convey different symbols changing the income expectation of the cooperation. Changes of such sort at length decide the possibility and degree of their cooperation. The research on the motivation of local government cooperation on supervision provides marginal contribution for the research on the behavior trend of local government in China under the pressure system, and offers a perspective for cooperation between China’s east and west regions on the next stage of rural revitalization.

Types of corruption in China, recent literature tells, are constantly evolving with the change of political and economic environment, a trend which is told mainly by a decrease of the number of self corruption while an increase of the number of transactional corruption. Such a conclusion runs against the finding based on the quantitative analysis of the indictment text data, that is to say,there has not been a noticeable decline of self corruption in comparison. The two almost weigh the same in absolute quantity, while bear obvious differences in their distribution and sources. Two contributors, a further data analysis finds, stand out as important structural sources of self corruption in China： one lies in rural grassroots political power because there lies a lot of opportunities to embezzle, misappropriate and falsely claim various funds allocated; the other government size because higher proportion of fiscal expenditure in GDP offers more opportunities for public office holders to occupy public property.

Artificial intelligence algorithm represented by deep learning, though bearing breakthrough characteristics, is applied in government departments in an embedded mode. Such an application starts from algorithm decision-making, and step by step is found available among administrative rules, administrative power and bureaucratic structure. The bureaucratic structure of government can choose algorithmic decision-making, and the bureaucratic system will not disappear. The influence of algorithm embedded includes instrumentality, embeddedness, autonomy and destructiveness and the controllable algorithm runs out of control when the system is missing or fails. A comprehensive embedding, as for the application of public domain algorithms in China, formed by extensive participation under the high-level promotion, brings forth systematic risk resulted from data leakage and algorithm out of control, a situation which renders an integration of the network security framework a necessity for continuously facilitating the management and control.

The mobile society poses a collaborative challenge to the grass-roots social governance, that is to say, the status of “Unit” in the mobile social governance system has been weakening with the overall transformation of social governance unit, a shift from “unit” to “community”. The social governance function of “Unit” was reactivated by the COVID-19, and it was integrated into social governance in its own way. “Unit”, empirical facts tell, is still an important dimension in the social governance system and bears organizational, professional, and technical advantages as well as that of we-media, weights of such sort which has constructed, in response to COVID-19, double identification and double pressure for unit members, and provided material and spiritual support for the community epidemic prevention and control embedded in it.The role of “Unit” in enhancing risk awareness and enhancing anti -risk confidence, therefore, should not be underestimated. The new model formed by its being integrated into “community system” meets the needs of governance in the context of mobile society, thereby a unique governance of China.

This paper combines the basic theory of the Kano Model with the elements of online classroom learning experience, and the key experience elements are determined through the steps of Kano questionnaire design and survey, survey data analysis and selection of improvement elements. The results show that： 39 learning experience elements need to be improved, of which 7 weigh most and affect learners’ learning experience, such as the establishment of feedback system, the relevance of course content, and the quick search function; the setting of course duration is irrelevant as it has no impact on learning experience; a need to register for online browsing and set student qualification falls into reverse element which has a negative impact on learning style. As for online classroom service, more functions provided do not necessarily bring forth more benefit, that is to say, the service should be designed according to user needs.

Curriculum history, as it bears profound meaning of historical philosophy, should be in urgent need elucidated by integrating the perspective of historical philosophy and the text of curriculum history. Kliebard’s The Struggle for the American Curriculum (1893–1958) is regarded as a benchmark and model for the “historical turn” in American curriculum research. Kliebard, in the book,elaborates the historical view of multicomponent hybridization of American curriculum history research, and it is a progressive speculative historical philosophy; the theory of interest group of historical facts confirms Kliebard's moderate grasp in the analysis of historical philosophy; Kliebard, with instinct, realizes the text practice of narrating historical philosophy through telling the curriculum history story in the period of American Progressive Education. The concern, reflection and self-consciousness of historical philosophy are helpful to explore a kind of meta discourse of curriculum history.

Even with a surge of the scores of various indicators of Shanghai’s business environment in recent years, there lies still a gap compared with the world’s leading business environment cities such as New York and London. Under the new development paradigm, it has become particularly important for optimizing China’s business environment so as to expand and strengthen the market system promoted by domestic and international circulation. Our study shows that ：(1) Shanghai’s great progress lies in starting a business, getting electricity, and dealing with construction permits, even now still a headache, and the shortcomings lie in paying taxes, getting credit, protecting minority investors, trading across borders and resolving insolvency; (2) International comparison shows that ：1) Shanghai ranks higher in registering property and enforcing contracts; 2) New York and London have significant advantages in getting credit and resolving insolvency; 3) Singapore, Tokyo, Seoul and Hong Kong gain advantages in dealing with construction permits, paying taxes and protecting minority investors; 4) Berlin, Rome and Paris stand out in trading across borders. Accordingly, Shanghai should, for a better business environment, learn from the advanced international experience and practices in simplifying the approval process for credit and bankruptcy, refining the taxation system, strengthening intellectual property protection, combating commercial bribery, building a good political and commercial environment, and strengthening the institutional innovation of the free trade pilot zone.

The current economic uncertainty caused by COVID-19 and Sino-US trade friction has brought great challenges to China’s foreign trade development. To walk out of the shadow, China, while consolidating traditional advantages, should forge new competitive advantages, optimize the global market layout, and seek new directions and outlets for the high-quality trade development. How to expand foreign trade diversification is a hard nut at the current stage. This paper, after sorting out more than 200 articles in important academic journals, summarizes many factors affecting the diversification from the supply side and the demand side and provides a breakthrough path that China needs to consolidate traditional advantages, build new competitive advantages, and optimize the global market layout, thus achieving the transformation from a big trading country to a powerful trading country.

Under the background of declining return on capital input and declining labor input, China needs to build a pattern of domestic and international circulation to enhance total factor productivity and promote high-quality economic development. This paper, adopting the theory of international economics, constructs the theoretical model of technological progress, economic growth and dual circulation system. Through economic simulation it finds that the key to build the dual systemlies in expanding the scale of domestic market. By analyzing Japan's attempt to build a dual circulation system, it is not difficult to find that the external circulation works well while the internal oneruns opposite. The wrong macroeconomic policy has triggered a bubble economy, resulting in a long-term downturn in enterprise investment and household consumption. China should learn from Japan's experience, strengthen government guidance so as to promote the stable development of dualcirculation.
