The comprehensive revitalization of Northeast China is a crucial support for achieving Chinese modernization. Due to systemic and structural issues， the development of market mechanisms in Northeast China has been relatively slow， leading to a slower pace of economic development compared to other regions. Further deepening of reforms is the fundamental driving force for advancing Chinese modernization and a necessary measure to achieve breakthroughs in the comprehensive revitalization of Northeast China. It is essential to seize the opportunity to integrate into the national unified market and build a high-level socialist market economy. It is necessary to create a policy environment conducive to the development of new productive forces， promote the upgrading of industries in Northeast China by cultivating and developing new quality productive forces. Comprehensive openness in Northeast China should be promoted， and an open economic system should be established through high-level openness to the outside world. Efforts should be made to accelerate the construction of a market-oriented， law-based， and internationalized business environment， facilitating new breakthroughs in the comprehensive revitalization of Northeast China.

New quality productive forces are the result of the qualitative change of traditional productive forces. There exists a relationship of dialectical unity between new quality productive forces and the new relations of production. Given that Northeast China has shortcomings and weaknesses in institutions and mechanisms， and economic structures， developing new quality productive forces in Northeast China can crack the bottlenecks in development， strengthen the new driving force of high-quality development and provide better support for Chinese modernization. In order to develop the new quality productive forces in Northeast China， the frontiers of scientific and technological innovation should be focused upon， the digital economy should be developed vigorously， a modern industrial system with unique advantages should be built， and a new type of workforce should be cultivated. Meanwhile， the new relations of production should be shaped through deepening reform comprehensively， which includes deepening the institutional reform in economy， education， science and technology， and talent， making every endeavor to create first-class business environment， and committed to extend high-standard opening-up. It is necessary to support the development of new quality productive forces in Northeast China from the national top-level design， such as setting up pilot zones for the development of new quality productive forces， reinforcing the layout of major productive forces， establishing special grain zones， and promoting the integrated economic development of Northeast China.

Developing new quality productive forces is an inherent requirement and an important focal point for promoting high-quality development， while industry is the core industrial sector for cultivating new quality productive forces. Compared to the theoretical logic of revolutionary technological breakthroughs， innovative allocation of production factors， and in-depth industrial transformation and upgrading required for the development of new quality productive forces， the role of scientific and technological innovation in Northeast China in promoting industrial economic development has not been fully exerted. Problems still exist， such as the not yet high level of innovative allocation of factors represented by the decline in economic benefits of industrial enterprises， the relatively slow pace of in-depth transformation and upgrading of traditional industries. Therefore， to promote high-quality development of Northeast China industry with new quality productive forces， it is necessary to increase investment in scientific and technological research and enhance technological support for high-quality industrial development， optimize innovative allocation of factors to help reduce costs and increase efficiency in the industrial field， accelerate industrial structure upgrading with a focus on in-depth integration of informatization and industrialization， and comprehensively promote the transformation of old and new drivers of growth in the industrial field to accelerate the process of new industrialization.

Trust is the cornerstone that constitutes human civilization. As society transitions to digitalization， algorithmic trust， as a product of the integration of technological trust and interpersonal trust， has adapted to the needs of a digitally transformed society and has become a key issue in the study of AI ethics. Algorithms have brought convenience to people's lives， but the flaws in their application have also triggered an inescapable trust crisis， which will affect the orderly operation of public and private areas of social life. Therefore， in order to promote the improvement of the overall trust environment in the digitally transformed society and to prevent technological risks， it is necessary to explore the intrinsic nature and conceptual characteristics of algorithmic trust from the perspective of technological evolution， and to clarify its constitutive logic. This will help reconstruct the ethical order of the digitally transformed society， strengthen legal regulation， avoid potential risks， ensure the orderly operation of social life， and guarantee the protection of human interests and well-being.

Man-machine interaction is one of the hottest topics in the field of artificial intelligence， and the problems， constraints， and development space of man-machine interaction often come from an in-depth understanding of human interaction capability. The core of human interaction capability lies in human emotion ability， and human emotions have both natural and social attributes， representing different levels of value. Therefore， taking the process of human beings' emotional change during man-machine interaction as the research object， a theoretical analysis framework of technical emotions is constructed around negative emotions that may arise during man-machine interaction， such as feelings of domination， attachment personality， technophbia， and deception. Such technical emotional regulation strategies as strengthening interpretability， understanding and respecting boundaries， eliminating the uncanny valley， consolidating trust foundation， and optimizing emotional monitoring are proposed. Targeted avoidance and regulation of many negative technical emotions can help create adaptive， harmonious， natural， and efficient human-machine symbiotic relationships between humans and machines.

Improving the quality of export products is the key to realizing high-quality economic development and building a strong trading nation. However， a large number of zombie enterprises trigger resource mismatch， and the impact of zombie enterprises on the quality of normal enterprises' export products has not yet been paid attention to. Accordingly， the impact of zombie enterprises on the quality of normal enterprises' export products is empirically examined using the micro data of Chinese listed enterprises from 2009 to 2015 as the sample. The results show that zombie enterprises have a significant negative impact on the quality of normal enterprises' export products， and the conclusion still holds true after a series of robustness and endogeneity tests. Heterogeneity analysis shows that the negative impact of zombie enterprises on the quality of enterprises' export products is more obvious in private enterprises， enterprises that do not receive government subsidies， and enterprises in the central and western regions. The mechanism test finds that the resource mismatch triggered by zombie enterprises reduces the labor productivity and R&D and innovation investment of normal enterprises， thus affecting the quality improvement of export products.

The welfare value of family consumption will be smoothed and realized through the impact of New Rural Cooperative Medical Insurance on the consumption structure. Based on the micro-panel data， the results show that increasing the family engagement rate will have a promotion effect on the medical consumption and have a crowding-out effect on the subsistence consumption. Further grouping of consumption results show that the crowding-out effect is mainly reflected in survival consumption. The interaction effect analysis of income and insurance engagement rate shows that the smoothing effect of the family engagement rate on various household consumption has heterogeneity about income. Increasing family engagement rate has a significant crowding out effect on non-medical consumption and survival consumption of middle or high-income families in high engagement rate of families， but the crowding out effect on low-income families is not significant. The research conclusion indicate that the Rural Cooperative Medical Insurance cannot meet the medical consumption needs of the middle and high income groups， and it is urgent to design and improve a multi-level insurance system.

As an important variable that restricts investment functions and operating conditions of the Chinese stock market， investors' information asymmetry can aggravate investors' losses and damage market liquidity. The information constraints faced by different types of investors are heterogeneous， i.e.， institutional investors are more significantly affected by the marginal impact of investors' information asymmetry， while retail investors suffer from a greater degree of information asymmetry and more severe investment losses. The GEM market has undergone major changes in the issuance review system from the approval system to the registration system， and the market information environment has improved significantly， which has led to a significant and continuous decline in the degree of investors' information asymmetry in the GEM market. However， this policy effect is heterogeneous， that is， the degree of institutional investors' information asymmetry has decreased significantly， but there is no evidence to support the decline in the degree of retail investors' information asymmetry.

Secondment is a flexible employment system used by local governments in China to cope with personnel constraints， reflecting the tacit agreement and consensus formed by superiors and subordinates to achieve governance goals and accomplish governance tasks. Based on the theoretical framework of governance-oriented collaboration， the types of secondment and its generative logic are analyzed， and secondment is viewed as a positively oriented superior-subordinate and organization-individual collaboration strategy that takes governance achievement as the goal. There are four types of grassroots civil servants' secondment in China: pressure transmission-authority obedience， resource supply-opportunity competition， task orientation-responsibility fulfillment， and strong mobilization-rational compliance. In terms of generative logic， grassroots civil servants' secondment is the result of a multifaceted strategy of institutional flexibility-resource embedding-individual choice mobilized by the goal of governance. Institutional flexibility explains the possibility of grassroots civil servants' secondment from the institutional level， and points out that secondment is the flexible room of the personnel system left by the local governments to deal with governance uncertainty. Resource embedding analyzes how to promote the process of grassroots civil servants' secondment at the organizational level， suggesting that secondment is an informal allocation process of human resources within the bureaucratic system facilitated by the superior departments based on power and opportunity resources. Individual choice focuses on the micro-action logic of the seconded grassroots civil servants， pointing out that whether an individual agrees to the secondment is a rational choice based on the consideration of institutional compliance and resource acquisition.

Unlike other ways in which Party building leads community governance， the practice of “Party Members Going Deep into the Grassroots” reflects the supportive role of a large number of in-service Party members under the unified leadership of party organizations with various organizational relationships outside the community in community construction， demonstrating the governance logic of external empowerment of political parties. In practice， it includes completing tasks according to community needs by in-service Party members (clicking on orders)， jointly promoting governance matters assigned by superiors of Party members and community cadres (task advancement)， relying on specific projects to optimize community governance (project co-construction)， and assigning Party members with long-term part-time positions as building managers and grid personnel (part-time positions). The above-mentioned four paths have played a positive role in filling governance resources， responding to the residents' demands， and implementing supervision and guidance in the community. In the future， the “three combinations” should be achieved， which are the combination of clarifying the responsibilities and missions of Party members and providing appropriate practical benefits and rewards， continuously endowing external governance resources with the optimization of the internal system foundation of the community， and assisting community cadres in advancing tasks together with deeply linking with the ordinary residents in the community. The practical model of external empowerment of political parties inherits the local experience of urban governance in the history of the Party and the country.

Based on the embedding theory， an analysis model is constructed from the four dimensions of institutional embedding， relationship embedding， cognitive embedding and resource embedding， and the effects of government procurement of community services from social organizations in the 22 pilot cases of S City are analyzed with the fsQCA method. The results show that the embedding of a single subject function does not constitute the necessary conditions for the good effect of government procurement of community services from social organizations. There are four paths that constitute the good effect of government procurement of community services from social organizations: resident cultivation type， government and social organization leading type， multi-subject linkage type， and community and social organization collaboration type. Among them， the two variables of the cooperation intensity between government and social organizations and the management level of resident service demand in the relationship embedding dimension constitute the core conditions. Multi-subject functional linkage is essential for the effect of government procurement of community services. In the future， it is necessary to focus on precise policy implementation from the perspectives of community service relationship network， government procurement of services system and organization construction， social organization cultivation and development， and multi-subject consensus on serving the people， so as to form an overall joint force to optimize the effect of government procurement of community services from social organizations.

The legality of generative artificial intelligence (GAI) development hinges on whether the act of copying vast amounts of texts during its training process constitutes copyright infringement. From the author-centered perspective， a work is seen as an extension of the author's personality or labor， entirely under the author's control. Unauthorized copying of a work by GAI infringes on the author's exclusive rights. Consequently， the traditional copyright infringement criteria have been based solely on “access + substantial similarity”. However， from the market-centered perspective， the author's copyright has market boundaries that do not extend to the areas of market failure beyond the primary market for the work. Therefore， the criteria for determining copyright infringement should be reconstructed， adding the element of “market harm” to the traditional “access + substantial similarity” framework. The focus should be on the impact of the work's use on its primary market. In the digital context， if GAI's massive copying of texts does not enter the market boundaries of the author's copyright， it cannot cause market harm and thus does not constitute infringement.

The theory of litigation elements determines the litigation form of joint and several liability guarantee from the perspectives of the parties， the ligation subject matter and the court jurisdiction， and determines the subjective and objective scope of judgment effectiveness. At the level of litigation subject matter， joint and several liability guarantees that debt has joint and several nature， hierarchical nature and relative independence. At the party level， it can be classified as an ordinary joint action through expanded interpretation， resulting in litigation forms of “joint action”， “separate action”， and “third-party participation”. At the level of court jurisdiction， it is determined by the different forms of guarantee litigation. The judgment on recovery right in a joint action guarantee litigation does not have negative res judicata or enforcement power， and the guarantor needs to file a separate lawsuit for recovery when pursuing compensation. In the separate action， the judgment of previous lawsuits should not have res judicata effect on the principal debtor as a non-party， and the preclusive effect is weakened to the evidentiary effect. In the third-party participation， the binding force of its participation effect can only be recognized while safeguarding the procedural rights of the principal debtor and taking into account the needs of litigation economy and fact-finding.

Facing the significant opportunities and challenges of a new round of technological revolution and industrial transformation， the CPC Central Committee with Comrade Xi Jinping at the core have put forward clear requirements for accelerating scientific and technological innovation. In recent years， Chinese universities have constantly innovated the mechanism of the whole scientific research chain focused on the national strategies， and actively carried out organized scientific research. Based on a combination of research review， case studies and in-depth research， this study analyzed the measures and distinctive work for the development of organized scientific research in high-level research universities. It has been confirmed that the four core elements of organized scientific research in universities are research tasks， build platforms， assemble teams， and provide funding. Various effective models for universities to carry out organized scientific research have been summarized， including improving the management function structure， supporting the construction of national laboratories， cultivating and optimizing innovation platforms， facilitating substantial interdisciplinary collaboration， and enhancing the ability to originate innovations.

Building a governance system for engineering education in China is an inevitable choice for solving the persistent problems in the field of engineering education， empowering the cultivation of a large number of outstanding engineers， and building a world-important talent centre and innovation highland. Based on the policy network theory， the governance of engineering education in China has gone through three stages of historical development from government section-led， expanding multiple subjects to building governance networks. In terms of the symbolic elements of engineering education governance in China， it shows that the scope of governance subjects continues to expand and the types of subjects are becoming more and more diversified， the governance structure continues to expand from a single hierarchical form to a mixed form， the selection of governance tools gradually shifts from an emphasis on regulatory commands to a focus on macro-guidance， and the consultation mechanism， the communication mechanism as well as the pilot mechanism have gradually been established. However， at the same time， problems are highlighted as well， e.g.， the structure of the pluralistic main bodies still needs to be optimized， the degree of resource integration of the governance network is not high， the development and application of governance tools are insufficient， and the operational guarantee mechanism still needs to be improved. In the future， China's engineering education governance system should be improved by giving full play to the key advantages of the government's meta-governance role， continuing to promote the linkage and interaction between internal and external networks， focusing on the combination of regulatory management and soft law governance， and continuously improving the consultation mechanism and information flow mechanism.

J.G.Ballard's Concrete Island intricately portrays the deserted traffic island within the city， a distinctive space whose special significance has been largely overlooked by the existing studies. Viewed through the lens of Soja's “Third Space” theory， it is evident that the novel's depiction of the deserted traffic island constitutes a “Third Space”. Here， Ballard elevates the awareness of such spaces， reflecting the dilemmas of modern interpersonal relationships. Besides， the infinite potential of the “Third Space” transforms the abandoned traffic island into individual havens for the city's “others”， thus communicating a sense of humanitarian care for the marginalized. Furthermore， the anti-hegemonic and anti-oppressive attributes of the “Third Space” foster a dynamic of checks and balances among the three protagonists， each with distinct social identities， thus unveiling an implicit critique of capitalism.
