The Department of Domestic Development Cooperation is centered on the theory of New Structural Economics. It conducts industrial‑policy research and planning for various national ministries, commissions, and local governments at all levels (province, city, county, district). It also provides industry and policy consulting services, as well as professional training programs, to enterprises and public institutions. Its purpose is to align closely with the broad direction of China’s economic‑policy development, integrating practical experience from China’s industrial development with cutting‑edge academic research. It offers the most authoritative and actionable industrial policies and plans to governments at all levels, enterprises, and institutions, delivering comprehensive research, consulting, and coordination services covering the entire spectrum from “theoretical research — industrial policy — investment promotion planning.” As a national high-end think tank , it submits internal reports on economic‑policy development to the central government, embodying the NSE policy-research philosophy of “the Unity of Knowledge and Action”—ensuring that research insights directly inform policy design and implementation. After nearly 10 years of exploration and practice, the Department of Domestic Development Cooperation has provided high‑end think‑tank services—such as economic‑policy and industrial‑planning advice—to ministries including the National Development and Reform Commission, the Ministry of Civil Affairs, the Ministry of Education, the Ministry of Natural Resources, the National Forestry and Grassland Administration, and the National Rural Revitalization Administration. It has also served dozens of local governments, including those of Jilin Province and the Xizang Autonomous Region. The department has established collaborative relationships with more than 100 domestic and international universities, think‑tanks, investment institutions, media outlets, and international organizations. Over time, it has forged a distinctive development path driven by a “dual‑engine” of discipline building and think‑tank construction, reinforcing each other.
