本文利用中国29个省区的面板数据，分析了PM2.5浓度的时空特征。利用空间Durbin模型实证考察了能源发展和技术创新对PM2.5的影响。结果表明：中国省际PM2.5呈倒“N”型变化趋势；省际PM2.5存在空间集聚现象，且空间自相关显著。邻域权值和距离权值的空间自回归系数均显著为正，邻域PM2.5污染对区域具有正向影响。从能源发展的角度来看，能源强度的提高将显著提高相邻区域的PM2.5浓度，从而提高全球PM2.5浓度。煤炭消费比重的上升，导致该地区乃至全球PM2.5浓度上升。能源消费价格上涨将降低区域和全球PM2.5浓度。从技术创新角度看，规模以上工业企业新产品销售收入增加，将使本地区PM2.5浓度降低0.1285个百分点，使周边地区PM2.5浓度降低0.3058个百分点，将使全球PM2.5浓度降低0.4343个百分点。专利申请量的增加将降低周边地区和全球的PM2.5浓度。该地区技术创新基础设施水平的提高将降低邻近地区的PM2.5浓度。技术市场成交额的增加，会降低该区域的PM2.5浓度和相邻区域的PM2.5浓度，从而降低全球PM2.5浓度。为了降低中国PM2.5浓度，我们应该继续推进PM2.5区域协同治理。在能源发展方面，要降低能源强度，优化能源结构，实施能源替代，理顺能源价格。在技术创新方面，要增加工业企业新产品销售收入，提高专利申请授权量，大力提高技术创新基础设施水平，提高技术市场成交额。
Using the panel data of 29 provinces and regions in China, this paper analyzes the temporal and spatial characteristics of PM2.5 concentration. The spatial Durbin model is used to empirically examine the impact of energy development and technological innovation on PM2.5. The results show that the interprovincial PM2.5 in China showed an inverted “N” trend. There is a spatial agglomeration of interprovincial PM2.5, and the spatial autocorrelation is significant. The spatial autoregression coefficients of adjacent weights and distance weights are significantly positive, and PM2.5 pollution in adjacent areas has a positive effect on the region. From the view of energy development, the increase in energy intensity will significantly increase the concentration of PM2.5 in adjacent areas, which will increase the global PM2.5 concentration. The increase in the proportion of coal consumption increases the concentration of PM2.5 in the region and globally. The increase in energy consumption prices will reduce the PM2.5 concentration in the region and globally. From the view of technological innovation, the increase in sales revenue of new products of industrial enterprises above the scale will reduce the concentration of PM2.5 in the region by 0.1285 percentage points and the concentration of PM2.5 in adjacent areas by 0.3058 percentage points, which will reduce the global PM2.5 concentration by 0.4343 percentage points. The increase in the number of granted patent applications will reduce the PM2.5 concentration of the adjacent regions and globally. The increasing level of infrastructure for technological innovation in the region will reduce the concentration of PM2.5 in adjacent areas. The increase in technical market turnover will reduce the concentration of PM2.5 in the region and the concentration of PM2.5 in adjacent areas, which will reduce the global PM2.5 concentration. In order to reduce the concentration of PM2.5 in China, we should continue to promote PM2.5 regional collaborative governance. In terms of energy development, it is necessary to reduce energy intensity, optimize energy structure, implement energy substitution, and rationalize energy prices. In terms of technological innovation, it is essential to increase sales revenue of new products of industrial enterprises, raise number of granted patent applications, vigorously improve level of infrastructure for technological innovation, and enhance technical market turnover.
