Logbook 3 Business ethics is the code of conduct that enterprises should follow in economic activities, which is not only related to the long-term interests of enterprises themselves, but also involves the responsibility to society and stakeholders. In my opinion, the core of business ethics is integrity and social responsibility. First of all, honesty is the cornerstone of business ethics. Businesses should deal with customers, partners and employees in a fair, transparent and truthful manner. Integrity is not only reflected in the quality of products and services, but also in honest marketing and communication. False publicity and fraudulent activities not only damage the reputation of enterprises, but also destroy the fair playing field of the market. Secondly, social responsibility is another important aspect of business ethics. Businesses are not only economic entities, but also part of society and should be responsible for society and the environment. By adopting sustainable business practices, companies are able to reduce their negative impact on the environment and make a positive contribution to their communities. At the same time, paying attention to the well-being of employees and providing fair pay and working conditions are also manifestations of corporate social responsibility. Finally, business ethics requires companies to consider the interests of all parties when facing decisions. We should not only pursue economic profit, but also pay attention to the interests of employees, customers, suppliers and society as a whole. Balancing the interests of all parties and avoiding harming the interests of others for short-term interests helps enterprises to establish a sustainable development model. Business ethics is not only the observance of laws and regulations, but also the embodiment of culture and values. When making business decisions, companies should take into account the long-term impact on human society and the environment. This includes respect for and protection of human rights, Labour rights, consumer rights and a commitment to environmental sustainability. In the era of globalization, businesses also play an important role on the international stage. Therefore, cross-cultural and transnational business ethics awareness becomes particularly important. Respecting national cultural differences and following local regulations, while incorporating global best practices into business operations, helps build international trust in companies. In addition, business ethics also requires enterprises to continue to pay attention to data privacy and information security in the era of technological innovation and digitalization. Ensuring that customer and employee information is properly protected against potential data misuse is an important task for companies to maintain business ethics in the digital economy. In today's complex and changing business environment, following good business ethics not only helps companies establish a good brand image, but also wins the trust of customers, increases employee satisfaction, and lays the foundation for long-term development. Business ethics is not only the key to the success of enterprises, but also the cornerstone of the harmonious development of society. In general, business ethics is a bridge to build a harmonious relationship between companies and society, the environment and stakeholders. Through honesty, social responsibility and multi-stakeholder balance, companies can achieve sustainable operations, promote the healthy development of society, and thus achieve broader success. Guided by business ethics, companies can better adapt to change, build solid reputations, and create a more sustainable future for the global community. In today's complex and changing business environment, following good business ethics not only helps companies establish a good brand image, but also wins the trust of customers, increases employee satisfaction, and lays the foundation for long-term development. Business ethics is not only the key to the success of enterprises, but also the cornerstone of the harmonious development of society.
