On the one hand, by developing ecological agriculture and circular agriculture, the originally separated links of planting, breeding and tourism are organically connected, and resources are recycled within the industry chain, reducing dependence on external inputs and pressure on the environment, and achieving simultaneous improvement of economic and ecological benefits. Farmers are no longer just providers of primary products, but sharers of value-added in the entire industry chain, gaining more benefits from green production. On the other hand, we should fully tap the endowment of local biological resources, use scientific and technological means to enhance their added value, and transform natural capital into economic capital. For example, the value of authentic medicinal materials and special forest products has increased exponentially through branding and deep processing. This model breaks through the limitations of traditional agricultural value creation and makes "green waters and green mountains" truly a sustainable "gold and silver mountain". The combination of biotechnology and ecological concepts runs through the entire process of industrial chain reshaping. From breeding of fine varieties, ecological breeding to processing and value-added, each link has the injection of scientific and technological innovation, making each link of the industrial chain both independent and efficient and synergistic in value-added. This endogenous growth model overcomes the bottleneck of extensive growth and explores a path for high-quality development for mountainous counties. In short, the bio-oriented green industrial chain provides a new value creation mechanism for rural revitalization: it not only maintains the natural background of the countryside but also activates the economic elements of the countryside, and truly achieves a win-win situation in economic, social and ecological benefits. This is also of great reference significance for other regions with rich ecological resources but underdeveloped economies. China's exploration of green agricultural development will provide valuable experience for the world. The case of Pan'an is a vivid embodiment of this view: through trial and error, a successful paradigm for biotechnology to promote the green transformation of agriculture has been explored, and its value path is worthy of wider promotion and application. After more than ten years of iteration and improvement, Pan'an's "Our Happiness Plan" has become a banner for the common prosperity of mountainous villages, and its connotation practice includes a wealth of biological strategy applications. From the formulation of ecological breeding standards to the layout of diversified biological industries, to the promotion of production-village integration and cultural tourism integration, all revolve around the purpose of "ecological priority and enriching the people". The successful implementation of this plan proves the feasibility of leading industrial revitalization with the concept of ecological civilization, and also provides a paradigm reference for rural revitalization across the country. First, the "Happiness Plan" highlights ecological industrialization and has embarked on a road of common prosperity that combines agricultural efficiency and ecological value-added. Its core experience lies in giving full play to the power of the three parties of government, enterprises and farmers: the government provides policies and public services, leading enterprises drive technology and market development, and thousands of households actively participate in production to jointly build a vibrant rural industrial ecosystem. The practice of "first the rich lead the poor, build and share common prosperity" has enabled more than 3,000 households and tens of thousands of farmers to increase their income at their doorsteps, with an annual total increase of more than 15 million yuan. This co-construction and sharing model is a vivid annotation of the goal of "common prosperity" in rural revitalization in the new era. Secondly, the "Happiness Plan" combines traditional culture with modern industries to promote the overall progress of rural society. While developing ecological agriculture, Pan'an pays attention to inheriting the culture of medicine, tea culture, and folk culture, and integrates them into industrial planning. For example, the Chinese medicinal materials industry chain has driven the cultural tourism of traditional Chinese medicine, and the development of farmhouse homestays has promoted the culture of rural hospitality. These have enhanced the connotation of rural revitalization. Thirdly, the "Happiness Plan" creatively integrates biotechnology elements to improve the scientific and technological content of rural revitalization. From the introduction of improved varieties, biological control to processing research and development, and brand building, each step has been injected with scientific and technological power, so that rural industrial revitalization is not a return to backward self-sufficient agriculture,
