Energy is the basis for development of material civilization. Since fossil energy can cause environmental problems, clean energy has become the trend of energy development. Solar energy is a kind of resource-rich and clean energy. Therefore, it exists great prospects of development. In addition, the cost of photovoltaic power generation is relatively high, and governmental subsidies are required. In this paper, we propose a spatial econometric model to analyze performance of government subsidies for the photovoltaic industry. When spatial dependence is obvious, classical econometrics begins to fail. At this time, spatial econometrics came into being. This paper evaluates the support policies of photovoltaic industry based on the premise that there is spatial dependence among regions. The results show that the installed capacity of photovoltaics in various regions has begun to show a significant positive correlation since 2012.What's more, the feed-in tariff and R&D subsidy policies have played a positive role in photovoltaic installed capacity from 2012 to 2018. It significantly contributes to the transformation of photovoltaic industry policy. At the same time, this paper expands the application scope of spatial econometric model.

能源是物质文明发展的基础。由于化石能源会引起环境问题，因此清洁能源已成为能源发展的趋势。太阳能是一种资源丰富的清洁能源。因此，存在很大的发展前景。另外，光伏发电的成本相对较高，并且需要政府补贴。在本文中，我们提出了一种空间计量经济学模型来分析政府对光伏行业补贴的绩效。当空间依赖性很明显时，经典计量经济学就开始失败。这时，空间计量经济学应运而生。本文在区域间存在空间依赖性的前提下，对光伏产业的扶持政策进行了评估。结果显示，自2012年以来，各个地区的光伏装机容量已开始显示出显着的正相关性。此外，2012年至2018年，上网电价和研发补贴政策对光伏装机容量起到了积极作用。极大地促进了光伏产业政策的转变。同时，本文扩展了空间计量经济学模型的应用范围。
