The obvious manifestation of urban development is the integrated development of urban architectural design and construction. The environmental protection of green building design and construction has become an important link that cannot be ignored in the process of urban green development. Green building materials, green design, and other environmentally friendly building programs are the subjective manifestations of the implementation of the green development concept. However, the degree of environmental protection is still a black box that needs to be explored urgently. To explore the environmental pollution caused by urban architectural design and construction in the process of urban development, an evaluation model of urban architectural design and construction on environmental pollution was constructed. The first-level evaluation indicators include ecology, natural, and social environments, of which the corresponding secondary indicators mainly include noise, water, and air pollution and other 12 indicators. The weights of the evaluation indicators at all levels were calculated using the expert evaluation method, and the weighting method was then combined to evaluate the pollution. Results show that the main sources of environmental pollution caused by urban building design and construction are solid waste pollution and traffic congestion rather than traditional noise and air pollution. Noise and air pollution are effectively controlled in the construction process. The evaluation system provides further directions for improvement in the prevention and control of environmental pollution in building construction and provides a reference for effective improvement of environmental governance.

Public awareness and knowledge of environmental protection are crucial to avoid environmental pollutions. Lack of relevant scientific principles and lack of public awareness of environmental or other projects are hindrances to controlling environmental pollution. The objective of the study was to identify the importance of public awareness in environmental pollution management. Environmental education and public awareness are crucial to avoid environmental pollutions. The study aims to analyze public awareness of environmental protection. The study was conducted in Sharana, the center of Paktika province, and was attended by 71 students from the Paktika Higher Education Institute’s Education Faculty. Questionnaires and field observations have been selected as methodologies for this research. The results of the study show that 59.2 percent of survey participants consider public awareness and 35.2 percent think that enforcement of environmental laws is important. People in Paktika do not take part in environmental activities due to a lack of public awareness and throw away pollutants everywhere. If this situation continues, it is not far off that it will turn into a disaster.

Environmental protection concerns the global and long-term development of the social economy. The negative effects of production and management activities of pollution enterprises on the environment attract more and more attention from the whole society. The government is not only continuously strengthening production regulation, responsibility monitoring and establishment of rules and regulations of pollution enterprises, but also increasing supports to environmental-friendly development of pollution enterprises. To explore influences of environmental regulations and environmental subsidies on enterprise investment to environmental protection, influences of environmental subsidies under environmental regulations were discussed through the propensity matching using data of listed enterprises in China’s pollution industry from 2013 to 2019. Results demonstrate that environmental subsidies promote the growth of enterprise investment to environmental protection significantly and environmental regulations are the primary influencing factor. According to heterogeneity analysis, environmental subsidies have significant positive effects on the investment in environmental protection of state-owned enterprises and private enterprises. The quantity and amplitude of investment in environmental protection of state-owned enterprises are more prominent. Environmental subsidies significantly promote investment in environmental protection of enterprises where senior executives have a technological background, but they have no significant influences on enterprises where senior executives have no technological background. Conclusions have some policy significance: government urges pollution enterprises to increase investment in environmental protection and pursue sustainable development from perspectives of incentives (increasing economic subsidies) and pressure (developing collaborative effect of environmental regulation).

Green innovation plays an important role in coordinating the relationship between ecological environment and economic development and has become a new driving force for the development of a resource-saving and environment-friendly economy. To explore the effects and logic of innovation efficiency and environmental protection, using the inter-provincial (city) panel data of the Yangtze River Economic Belt from 2007 to 2017 in China, the green innovation efficiency and environmental protection level of the upper, middle, and lower reaches of the Yangtze River Economic Belt were analyzed. Results show that the overall environmental protection level of the Yangtze River Economic Belt is on the rise. From a regional perspective, the environmental protection level in the upper reaches is the highest, which is greater than the overall level of the Yangtze River Economic Belt, followed by the lower and middle reaches, which are less than the overall level of the Yangtze River Economic Belt. The efficiency of green innovation has promoted the overall environmental protection level of the Yangtze River Economic Belt, inhibited the environmental protection level in the downstream areas, promoted the environmental protection level in the upstream areas, and has no obvious impact on the environmental protection level in the middle reaches. Further mechanism analysis shows that the possible transmission path of green innovation efficiency to environmental protection is as follows: green innovation efficiency promotes the environmental protection level by improving the ecological environmental efficiency. The robustness of the above conclusion is tested, and it has good robustness. The research conclusions of this study provide reliable empirical evidence and policy enlightenment for the development and optimization of green innovation efficiency and the realization of green innovation efficiency driving environmental protection.
