Based on the panel data of 11 provinces and cities in the Yangtze River Economic Belt from 2005 to 2018, this paper uses the SBM-DEA efficiency model with undesired output to measure the green innovation efficiency of the Yangtze River Economic Belt. The panel Tobit empirical analysis model was used to quantitatively analyze the impact of three different forms of government environmental regulations on the efficiency of green innovation. The research results show that the government’s mandatory environmental regulations and government financial subsidies for green innovation technology are two regulatory methods that positively promote the efficiency of regional green innovation, but government investment in environmental governance has a negative impact on the efficiency of regional green innovation. Then the study found that this negative impact has a significant inflection point effect: when it exceeds a certain threshold, the negative impact turns into a positive effect. At the same time, the impact of environmental regulations on the efficiency of green innovation has significant regional heterogeneity, and the three environmental regulations have a greater impact on downstream provinces and cities.
The urban-rural consumption gap under the infl uence of the household registration system is a social issue with Chinese characteristics. Can the current reform of the household registration system eliminate this gap? Using the survey data from Chinese Household Income Project (CHIP), this paper adopts the methods of Propensity Score Matching (PSM) and RIF (Re-centered Infl uence Function) Quantile Decomposition to quantitatively analyze the impact of changes in household registration on the consumption level of "urban hukou (household registration) obtainers" and the infl uence mechanism. Studies show: (1) There is still a signifi cant diff erence in the consumption level between "urban hukou obtainers" and urban natives after the citizenization, and the consumption gap between the two groups is even greater after taking endogenous problems into consideration; (2) The impact of the citizenization on the consumption level of "urban hukou obtainers" has a signifi cant heterogeneity. There are signifi cant consumption diff erences due to diff erent sources of the household registration, and this consumption gap has an expanding trend over time; (3) By decomposition, it is found that such consumption gap mainly comes from the gaps in income and social security between the two groups and its mechanism has been confi rmed.
In China, geographical indications (GIs) are seen as certificates or collective trademarks, as well as representations of quality agricultural products, and are important in revitalizing the countryside. Therefore, a combined qualitative and quantitative method was employed to examine the operational practices of GIs at the relatively micro-level of the municipality in order to identify their effectiveness and challenges in rural revitalization and propose more targeted optimization suggestions. Pengshui Miao and Tujia Autonomous County, located in the Wuling Mountains in southeastern Chongqing, is an excellent example of the positive impact GIs can have on rural development, boasting the highest number of GI trademarks in the region. Despite the large number of GIs in Pengshui, there are several issues that need to be addressed, including low brand awareness, lack of product enhancement, and poor market competitiveness. To overcome these challenges, there must be a shift from a quantity-based to a quality-based approach to GI trademark declarations. This requires promoting the transformation of traditional agriculture into modern agriculture, investing in rural infrastructure, and improving the efficiency and quality of GI product production. By doing so, individuals in the local community will be able to reap the benefits of GI trademarks, improving their income and standard of living. In view of the fact that administrative divisions and cultural regions overlap, it is important to promote interregional cooperation and encourage declarations of GI trademarks in neighboring counties. This will help to preserve the area’s local cultural heritage and promote its heritage through GIs. By taking a targeted approach to GI trademark declarations and promoting cooperation between regions, Pengshui, and other rural communities can maximize the benefits of GIs and support sustainable rural development.
As an important way and means to protect the legitimate rights and interests of workers, the implementation of the “Labor Contract Law” is crucial for building and developing harmonious and stable labor relations and the sustainable development of enterprises. Based on the samples of Shanghai and Shenzhen A-share listed enterprises from 2005 to 2013, this paper adopted the difference-in-difference method to empirically test the impact of labor protection on the sustainable development of enterprises and its mechanism. The research finds that the enhancement of labor protection contributes to the sustainable development of highly labor-intensive enterprises, in which enterprise innovation plays a mediating role in the relationship between the two; the heterogeneity test found that labor protection promotes sustainable development more significantly in state-owned enterprises, enterprises in highly market-oriented regions, and large-scale enterprises. This article expands the research on the economic consequences of labor protection and provides empirical inspiration for the improvement of the “Labor Contract Law” system.
