Impact of the 'Ten Measures for Soil' Policy on Urban Green Space Construction in Resource-Based Cities: A Baseline Regression Analysis

Table 3 reports the baseline regression results of the impact of the 'Ten Measures for Soil' policy on the construction of urban green spaces (UGS) in resource-based cities. The first column (1) shows the estimated results after controlling for a series of control variables, while the second column (2) shows the estimated results after controlling for city and year fixed effects based on the control variables. The results indicate that the estimated coefficient of city×year is significantly positive at the 1% level, regardless of the situation. This suggests that the soil pollution prevention and control measures have a significant positive impact on the construction of UGS in resource-based cities. The impact coefficients of the control variables, such as the city innovation index and marketization level, are both significantly positive, indicating that a favorable innovation and market environment can provide support for innovative technologies and economic foundations for UGS construction. The estimated coefficient of the ecological civilization level is also significantly positive, indicating that the higher the level of ecological civilization in a city, the more emphasis it places on UGS construction and actively promotes policy implementation. The estimated coefficient of foreign investment is consistently positive at the 1% significance level, indicating that foreign-invested enterprises have more capital to invest in environmental governance and technological transformation, thereby leading the transformation of polluted soil into green spaces. The impact coefficients of industrial upgrading are also significantly positive, indicating that a reasonable industrial structure can better lead the direction of green and sustainable development in cities and promote the construction of UGS.
