The disordered and rampant local tax incentives have interfered with regular business competition and resource allocation, and whether they have the rationality of existence has also become an urgent problem to be clarified. In China, the government has undertaken a new round of policy adjustment to comprehensively sort out and standardize tax incentives, trying to realign value-oriented tax competition among local governments. Thus, this paper examines the real effect of standardizing tax incentives using China's State Council documents Nos. 62[2014] and No. 25[2015], with the measurement of abnormal tax burdens and abnormal fiscal subsidies. The result shows that this round of policy governance has maintained the steadiness of the overall tax burden and fiscal subsidy, and only abnormal tax burdens and fiscal subsidies have been reduced through structural adjustment; In addition, it has also taken into account the difference among regional economic development. The governance in the Midwest is generally lighter than in the East. Meanwhile, the effect of governance among different property companies has presented a reduced tendency as "state-owned enterprises -- local state-owned enterprises -- private enterprises".

As the problem of global climate change becomes more severe, countries have proposed the goals of carbon capping and carbon neutrality. Green finance is an essential capacity support for achieving carbon peaking and carbon neutrality, and it can guide and stimulate social capital to invest in low-carbon industries and initiatives via marketbased mechanisms. Based on the panel data of Chinese prefecture-level cities from 2006 to 2020, this paper empirically examines the impact of green finance on carbon emission efficiency using a two-way fixed-effects model, conducts a regional heterogeneity analysis, and examines the threshold effect of economic development level and the mediating role of regional innovation. The results indicate that, first, green finance contributes significantly to the improvement of carbon emission efficiency, and second, the level of regional economic development has a double threshold effect on the contribution of green finance to the improvement of carbon emission efficiency. Third, regional innovation is an important green finance channel for influencing carbon emission efficacy. The sensitivity of carbon emission efficiency to the green finance index demonstrates an inverted U-shaped trend. Fifth, the importance of green finance sub-dimensions in relation to carbon emission efficacy is as follows: green support, green credit, green insurance, green investment, green equity, green bond, and green fund. These findings provide theoretical support for green finance's role in promoting co-carbon efficiency and are valuable for policy formulation.

Does the ancient farming culture shape the risk-taking behavior of households today? Using a dataset covering over 130,000 households from a Chinese national survey, our study examines the relationship between the culture of rice cultivation and the financial behavior of modern households. We find that households in regions with a higher rate of historical rice cultivation are more likely to invest in the financial market and buy lottery, but less likely to purchase insurance. We also find that the rice area has more households with risk preferences consistent with prospect theory expectations. To account for omitted variable bias, we use average regional rainfall and downstream distance to ancient irrigation systems as instrumental variables for rice cultivation, and our results remain robust. We find that the rice effect cannot be explained by regional economic development, traditional Confucian values, or ethnic diversity. To explore potential mechanisms, we find that households in rice regions are more likely to borrow money from friends and relatives and have interest waived, and historical commercial development has also been influenced by the rice culture.

We investigate the impact of strategic investors on bank efficiency in the context of regional economic development. The data on Chinese city commercial banks operating regionally are well-suited for the study. Findings suggest that strategic investors significantly increase efficiency in Chinese city commercial banks; the impact of strategic investors on the efficiency of Chinese city commercial banks is negatively correlated to the level of regional economic development. The negative correlation of the impact of strategic investors on Chinese city commercial banks’ efficiency with regional economic development may be explained by the mix of the local official promotion system and the city commercial banks’ governance structure.
