Matching mechanism in global public goods games:a case of climate protection

In the setting of dealing with climate change, this article designs a matching mechanism for global public goods provision with the aggregative game approach. Given endowment and the technology of each country, we propose the conditions under which the matching mechanism is able to guarantee full participation and Pareto efficient provision, respectively, in the cases with certain and uncertain preference information. These conditions cannot only be adopted in international negotiation and cooperation, but also refines the theory of matching game. In comparative static analyses, we discover that: First, changes of initial stock of climate goods produce a wealth effect and the crowd-out effect is less than 1. Second, climate tax policies affect the supply and welfare of each country only when they produce wealth effects, and if tax revenue is transferred into climate goods with more advanced technology, they will produce positive wealth effects. Third, modifying matching plans dynamically and appropriately can urge countries to improve technology, and especially given a Pareto optimal mechanism, adjusting the matching plan to keep marginal rates of transformation unchanged as technology changes is still able to ensure full participation and efficient supply of climate goods.

Software Metric Analysis of Open-Source Business Software

Over the past decade, open-source software use has grown. Today, many companies including Google, Microsoft, Meta, RedHat, MongoDB, and Apache are major participants of open-source contributions. With the increased use of open-source software or integration of open-source software into custom-developed software, the quality of this software component increases in importance. This study examined a sample of open-source applications from GitHub. Static software analytics were conducted, and each application was classified for its risk level. In the analyzed applications, it was found that 90% of the applications were classified as low risk or moderate low risk indicating a high level of quality for open-source applications.

The Theoretical Innovation and Exemplary Value of the Belt and Road Initiative

As a global public good, the Belt and Road Initiative proposed by the Chinese government features being "non-rivalrous" and "non-excludable," which are two essential characteristics of public goods. From design philosophy to operational framework, from vision to action, distinct Chinese characteristics, style and temperament are fully demonstrated by this initiative. In theory, the Belt and Road Initiative promotes multiple innovations in global governance and enriches and develops international cooperation and the global value chain. The "Silk Road spirit" inherits and innovates the core philosophy of China's diplomacy since 1949; more importantly, its principle of achieving shared growth through discussion and collaboration is a key contribution to global governance theory. In practice, the Belt and Road Initiative highlights both regional cooperation and international agreement, and initiates a new model for China's diplomatic practice and international cooperation. Therefore, it is of exemplary value in terms of development, peace, culture and cooperation, while offering a new solution to dealing with international relations in the era of Reform and Opening-up. The past three years has generated marked achievements. The Belt and Road construction is at a critical stage of transition from quantitative change to qualitative change, from small achievements to significant success. In the future, China should take the initiative to promote the construction of two principal axes, further integrate with the philosophy underpinning China's diplomacy as a major country, innovate the theoretical system of the Belt and Road Initiative and forge a corresponding security system. As the old Chinese saying goes, "Big countries should treat small countries with kindness and justice, while small countries should treat big countries with wisdom." China should properly address the competition and cooperation with countries along the Belt and Road and further advance institutional construction within the framework of its major country diplomacy.

Development of the Principle of International Solidarity and the Contribution of China

International solidarity is a fundamental value upheld by the united nations as well as a principle of international law recognized by independent experts on human rights The values and principle of international solidarity have played an important role in promoting human rights, improving the international economic order, driving sustainable development, and tackling global challenges, and they have gained wide support from most developing countries As unilateralism and protectionism continue to spread, global governance and multilateral cooperation are under threat Against this background, the united nations calls for the spirit and principle of international solidarity and the promotion of solidarity rights, including the right to development, and encourages the countries to safeguard global public health through joint actions and to avoid discrimination The concept of a community with a shared future for human beings proposed by China embodies international cooperation, mutual learning and exchanges, and collective efforts to promote and safeguard human rights It has made a positive contribution to enriching and boosting the principle of international solidarity and demonstrated the wisdom and responsibility of China as a major country.

Designing Trade Rules to Promote Climate Sustainability

Climate sustainability has become a key issue of our time. Measures protecting the environment, however, can have an impact on the competitiveness of domestic firms and on cross-border trade. Therefore, regulatory bodies should enlarge the scope of their policies and treat climate sustainability as global public good; based on such concept trade rules are to be designed in a way that allows a fair balancing between the diverse interests.

Software Analytics of Open Source Business Software

This paper applies software analytics to open source code. Open-source software gives both individuals and businesses the flexibility to work with different parts of available code to modify it or incorporate it into their own project. The open source software market is growing. Major companies such as AWS, Facebook, Google, IBM, Microsoft, Netflix, SAP, Cisco, Intel, and Tesla have joined the open source software community. In this study, a sample of 40 open source applications was selected. Traditional McCabe software metrics including cyclomatic and essential complexities were examined. An analytical comparison of this set of metrics and derived metrics for high risk software was utilized as a basis for addressing risk management in the adoption and integration decisions of open source software. From this comparison, refinements were added, and contemporary concepts of design and data metrics derived from cyclomatic complexity were integrated into a classification scheme for software quality. It was found that 84% of the sample open source applications were classified as moderate low risk or low risk indicating that open source software exhibits low risk characteristics. The 40 open source applications were the base data for the model resulting in a technique which is applicable to any open source code regardless of functionality, language, or size.
