This paper uses panel data from 25 provinces in China as the sample. We utilize a two-way fixed effect model, spatial Dubin model, and panel threshold model to discuss the impact of two-stage innovation efficiency on the value of the green brand, the spatial effect of this impact, and the threshold role of intellectual property protection in the process. The results indicate that: (1) the two stages of innovation efficiency have a positive impact on the value of green brands, and the effect of the eastern region is significantly better than that of the central and western regions. (2) The spatial spillover effect of the two stages of regional innovation efficiency on the value of green brands is evident, especially in the eastern region. (3) The innovation value chain has a pronounced spillover effect. (4) The single threshold effect of intellectual property protection is significant. When the threshold is crossed, the positive impact of the two stages of innovation efficiency on the value of green brands is significantly enhanced. (5) The influence of economic development level, openness, market size, and marketization degree on the value of green brands shows remarkable regional differences. In conclusion, this study contributes to understanding green brands\u2019 growth and provides important implications for developing independent brands in various regions of China.<\/jats:p>","DOI":"10.3390\/e25020290","type":"journal-article","created":{"date-parts":[[2023,2,6]],"date-time":"2023-02-06T02:57:32Z","timestamp":1675652252000},"page":"290","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Can the Sci-Tech Innovation Increase the China\u2019s Green Brands Value?\u2014Evidence from Threshold Effect and Spatial Dubin Model"],"prefix":"10.3390","volume":"25","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3653-5181","authenticated-orcid":false,"given":"Xiaofei","family":"Zhang","sequence":"first","affiliation":[{"name":"School of Economics and Management, Fuzhou University, Fuzhou 350108, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yang","family":"Xiao","sequence":"additional","affiliation":[{"name":"School of Economics and Management, Fuzhou University, Fuzhou 350108, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Linyu","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Economics, Zhejiang University of Finance and Economics, Hangzhou 310018, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,2,3]]},"reference":[{"key":"ref_1","first-page":"86","article-title":"Theory construction and measurement of green brand value based on the consumers\u2019 perspective","volume":"30","author":"Zhang","year":"2015","journal-title":"J.
