This study investigates the impact of Total Factor Productivity(TFP) growth in China's high-tech industry on household consumption, examining the distinct roles of labor and capital factor productivity from the perspective of biased technological progress. We innovatively construct a sequential proportional NDDF-Luenberger index. This index not only provides a theoretically consistent measure of TFP but also enables its precise decomposition into labor factor productivity and capital factor productivity, allowing for the quantitative identification of the degree and direction of technological bias. Our analysis yields three key findings. First, China's high-tech industry TFP evolved through a three-phase pattern of "surge–retreat–recovery," characterized by persistent capital-biased technological progress. Second, at the national level, improvements in overall TFP, labor factor productivity, and capital factor productivity all significantly promote household consumption, validating the theoretical pathway where supply-side efficiency gains stimulate demand. Third, significant regional heterogeneity exists: the Eastern region exhibits a "capital-led" growth pattern with weaker consumption effects from labor productivity; the Central and Western regions show "factor synergy," where both productivities contribute to consumption; whereas the Northeastern region suffers from a blocked transmission mechanism, where technological progress fails to significantly boost local consumption due to insufficient integration with the regional economy. By integrating supply-side TFP with demand-side consumption through the lens of biased technological progress, this research provides critical insights for fostering a virtuous cycle between innovation and domestic demand, offering valuable implications for industrial and regional policy design aimed at sustainable and inclusive growth.

This study investigates the effect of a large-scale Internet upgrade program in China on the consumption of rural households. Using data from the China Family Panel Studies, we find that the Internet upgrade at the village level significantly increases rural households’ expenditures on total, online, and ofline consumption. Moreover, high-educated and young households, as well as those living in difficult-to-access villages exhibit a larger boost in total consumption. The mechanism analysis rules out income as the possible channel but highlights the role of online information exchange. ln particular, the variations in the increase in online time among households align with the heterogeneous responses in total consumption.

Hukou, China’s household registration system, affects access to public services and signals the strength of a person’s local social network, guanxi. We use a collective model and data on household consumption and spouses’ hukou status to show that hukou plays a crucial role in determining within-family bargaining power. Wives who bring the family more lucrative hukou enjoy significantly higher bargaining power than other wives. Still, these wives have less bargaining power than their husbands. Large differences in preferences between husbands and wives, especially regarding alcohol, tobacco, and clothing, allow us to identify these disparities.

Over the past decade, the rapidly digitizing economy in China has attracted much attention in both academic and policy circles. Most existing studies focus on the positive impact digitalization has had on China's inclusive growth. Few of them have attempted to measure the widening digital divide and its potential impact. Using the 2017 and 2019 China Household Finance Survey (CHFS) data, this paper: (i) provides the first evidence that the digital divide has a significant negative impact on household consumption. For every unit increase in the digital divide, the level of household consumption will drop by about 28 percent; (ii) finds the negative impact stems from an integrated channel of rising unemployment, intensified liquidity constraints, and declining financial literacy; and (iii) further discloses that the digital divide has differential impacts on household consumption by category, while hinders consumption diversification. The results are robust to correcting for potential endogeneity due to sample selection, household heterogeneity, and reverse causality. Our findings shed new light on some little-documented evidence and have profound implications for related socio-economic policies that fully utilize technology to drive efficiency and inclusivity in the digital economy.

Our study shows that China could contribute to an orderly global rebalancing by a package of policies to stimulate its domestic consumption. These policies include a progressive appreciation of RMB, fiscal stimuli of increasing social expenditures on education, healthcare, social safety net and poverty reduction, income policies to reduce inequality and to strengthen wages income, and reforms of the financial system to improve financial efficiency and mitigate financial constraints. With these policies, China's external surplus can be narrowed along with an improvement of its domestic imbalances. The excessively high saving rate will be lowered and the share of household consumption will increase, even although GDP growth will moderate slightly.
