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

Abstract

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