Abstract: Purpose - The effect of market power on allocative efficiency is one of the most important topics in industrial organization and has undergone rigorous investigation since the 1970s. However, empirical studies based on firm-level data are relatively rare, especially with regard to China's tobacco and food industries. Accordingly, this research measures market power and allocative efficiency loss (AEL) of the main tobacco and food industries in China with micro data at firm level. Subsequently, it conducts a comparative analysis on them. Design/methodology/approach - This research applies the New Empirical Industrial Organization (NEIO) model, consisting of five pricing and demand simultaneous equations to measure market power, and the AEL model to measure AEL induced by market power. To match with the micro data at firm level, the study implements a change in the traditional NEIO model by abandoning the aggregating process. Findings - Empirical results show that China's tobacco industry, among five sectors selected, has the largest market power and thus the highest degree of AEL, whereas other sectors have apparently smaller market power and lower levels of AEL. Comparative analysis demonstrates a coarse positive correlation between market power and AEL in the selected industries. In general, the results accord well with the existing empirical findings and the reality. Research limitations/implications - This study has some deficiencies. First, owing to the limitation of high-quality data, the sectors analyzed in this research are insufficient to sum up all the characteristics and rules of China's whole food industry. Second, this research only analyzes seller market power and leaves out buyer market power, which could be a direction for future research. Practical implications - The relevant administrations should strictly limit the monopoly behaviors of enterprises and establish a favorable and competitive market environment, especially for the tobacco industry. This suggestion is precisely an important content of China's Supply-side Reform. Originality/value - The research improves the NEIO model in that it can be estimated with micro data at firm level. To the best knowledge of the authors, very few empirical and comparative analyses exist on market power and AEL for China's tobacco and food manufacturers using micro data.
