Study on the Technological Inductive Effects of Product Information Label: Evidence From the Energy-Efficiency Labeling System in China

Under the dual goals of achieving carbon peak and neutralization, it is great practical significance to explore impact product information labeling on technological innovation. As an essential element in improving energy performance consumer products, energy-efficiency labels (EEL) have played a vital role government’s portfolio improvement, progress, emission mitigation. We estimate extent inductive effects varying patent types relationship between EEL system innovation panel differences-in-differences framework based data energy-saving patents electricity-saving from 1998 2013 China. Results indicate that helps firms improve ratio water-saving patents, rate all region. In another word, has significant directed inducing effect. for heterogeneity types, positive invention are significantly suppressed patent-for-utility models. Thus, suggested existing system, gradually expand coverage increase protection scope utility model progress sustainable development society.
