China’s technical progress on emissions and vast ocean area make the study for CO2 emission reduction suitable in a marine fishery. This study uses the slack variables of SBM and the Malmquist index to analyze the CO2 emission efficiency of Trawler, Seine net, Drift net, Fixed net, and Angling, along with their efficiency values, distinguishing the impact of technological progress, scale expansion, and technological efficiency. Results show that the CO2 emission efficiency of the Angling and Seine industry is high with the development potential of the low-carbon fishery. Moreover, China’s technological progress is increasing, but the technical efficiency of CO2 emission reduction is declining. Lack of pure technical efficiency is the primary constraint of low-carbon capture fishery, making changes in efficiency show a downward trend. These results expand the research depth of the efficiency impact of technological progress and reveal that technological progress keeps increasing, but the CO2 emission reduction efficiency is decreasing. This indicates that emission reduction requires both technological growth and the technology’s capacity to reduce CO2 emissions efficiently.

This paper explores the change of enterprises’ investment following the financing system reform through the established stochastic investment model. In this constructed model, financing property, market-oriented reform, and government intervention are regarded as a stochastic process. Furthermore, the modern China’s economic situation is interpreted to analyze the enterprises’ investment by government intervention plan combined with he deduced proposition from the stochastic investment model. The results provide a depth understanding for characteristics of the enterprise in China that the steady capital of state-owned enterprises’ investment is higher than that of non-state-owned enterprises without government intervention before completing financing reform. Although government intervention can increase the investment level of state-owned enterprises, doing so increases the turbulence of the market economy. Additionally, the impact of government-led financing reform on enterprises’ investment is asymmetrical. Promoting market-oriented, clear-cut financing reform, and reducing government-led investment plans will improve enterprises’ investment efficiency and stabilize China’s economic development. The present paper provides a specific future orientation of China’s financing reform determining the level of enterprises’ investment.

The general view is that land ownership affirmation provides incentives for farmers to internalize external benefits, optimizes farmers’ allocation of agricultural production factors, and then reduces farmers’ farmland wastage behavior. This study examines the influence of residual control and claim rights in farmland right confirmation on farmers’ farmland wastage behavior. Results show that residual control rights guarantee the farmers’ exclusive right to use the farmland independently, and residual claim stimulates the farmers to pursue the goal of agricultural production surplus value. However, the residual claim rights are related to the constraint conditions of agricultural production; thus, the farmland right confirmation is situational dependent on farmers’ farmland wastage behavior. The surplus value of the farming output of low-income families is low, and the willingness to realize the surplus claim through agricultural reproduction is weak. Residual control reduces the risk of land loss, accelerates the transfer of the labor force, and shows the behavior of farmland wastage. Nonpoor households with high agricultural production surplus value tend to increase the allocation of agrarian production factors to maximize the income, improve the allocation efficiency of agricultural land resources, and reduce farmland wastage behavior. Conclusion: The implementation effect of accurate farmland affirmation is progressive and internally unbalanced. The institutional basis of matching policy should be to deal with the relationship between residual control right and residual claim right.
