Extended abstract:[Background and purposes] China's ceramic industry has a long history. Since the reform and opening up, the industry has been developed rapidly, forming a diversified industrial system, including architectural, daily-use, sanitary, garden art ceramics and special ceramics. Among them, advanced ceramics, as an important component in the new materials, have promoted the development of industries, such as biotechnology, electronics and new energies, becoming a key part of the country's strategic emerging industries. However, compared to global ceramic technology, domestic innovation is still insufficient. The concept of "new quality productivity" proposed by General Secretary Xi Jinping emphasizes the leading role of technological innovation in industrial transformation. The new quality productivity of the ceramic industry, with technological innovation at its core, is the key to driving high-quality industrial development. As important representatives of China's ceramic industry, Chaozhou in Guangdong and Jingdezhen in Jiangxi both have supported the upgrading of the ceramic industry through policy support and industrial transformation. This work was aimed to construct an evaluation index system for the new quality productivity of the ceramic industry, and combine the entropy weight method to compare the new quality productivity levels of the two regions. It not only fills the gap in empirical research on new quality productivity in the ceramic field but also provides empirical support for the high-quality development of the ceramic industry.[Methods] This study is based on the productivity three-factor theory model proposed by Wang Jue (2024) and combines Marxist productivity theory to construct an evaluation index system for the new quality productivity of the ceramic industry. The system covers three dimensions: new-type laborers, new-type labor objects and new-type labor materials. For new-type laborers, indicators, such as "number of R&D personnel in industrial enterprises above a designated size," "number of employees in the ceramic industry," and "per capita ceramic output value of ceramic workers", are used to measure labor skills and productivity. New-type labor objects are assessed through the scale of the ceramic industry and green, low-carbon indicators. New-type labor materials are evaluated based on digital infrastructure and technological innovation. To ensure the objectivity of the measurement results, the entropy weight method was used to evaluate the new quality productivity of the ceramic industries in Jingdezhen and Chaozhou, avoiding the limitations of subjective weighting methods.[Results] The development level of the new quality productivity in the ceramic industry in Jingdezhen and Chaozhou from 2017 to 2022 was analyzed. Jingdezhen's new quality productivity increased from 0.3267 in 2017 to 0.7233 in 2022, with an average annual growth rate of 21.98%, showing significant improvement driven by the "Experimental Zone" policy. In contrast, Chaozhou's growth was slower, Chaozhou's new quality productivity increased from 0.5036 in 2017 to 0.5252 in 2022, with an average annual growth rate of only 1.05%, though it saw a recovery after 2020 through intelligent production and talent introduction policies. Jingdezhen is strong in hard power, with notable innovation in the ceramic industry, but its talent support needs strengthening. Chaozhou, on the other hand, excels in soft power and talent introduction but needs to enhance green innovation. Jingdezhen should focus on talent introduction and upgrading its industrial chain, while Chaozhou should promote green development by optimizing environmentally friendly materials and processes. The weights of various indicators were calculated using the entropy weight method, revealing different development trends in the new type of laborers, labor objects and labor materials between the two cities.[Conclusions] An evaluation index system has been constructed for new quality productivity in the ceramic industry, the entropy method was used to analyze the development level of new quality productivity in the ceramic industries of Jingdezhen and Chaozhou from 2017 to 2022. The overall development level of Jingdezhen is higher than that of Chaozhou, with significant productivity improvements driven by the "Pilot Zone" policy, from 0.2095 in 2018 to 0.7233 in 2022, while Chaozhou's growth remains slower. Jingdezhen's ceramic industry excels in hard power but lacks sufficient talent support. In contrast, Chaozhou stands out in soft power and the recruitment of digital and intelligent talent, but green innovation needs to be strengthened. In terms of policy implications, Jingdezhen should focus on strengthening talent development to promote the overall upgrading of the ceramic industry, while Chaozhou should increase research and development of green environmental materials and processes to drive industrial green transformation and improve ecological benefits.
