我国太阳能热水器产量和保有量居世界第一,但普及率及市场占有率较低,且缺乏对太阳能热水器的补贴和税收优惠,太阳能热水器的环境效益被大大低估。运用可再生能源发展阶段理论识别出我国太阳能热水器产业处于从商业化初期向成熟化过度阶段,目前该产业仍需要国家支持。建议政府对社会弱势群体购买太阳能热水器给予补贴,并对有一定规模的太阳能热水器企业给予环境效益的补贴。 China’s solar water heater production and possession of the largest in the world, but the penetration rate and market share is low, and the lack of subsidies and tax incentives for solar water heaters, solar water heaters, environmental benefits have been greatly underestimated. Use of renewable energy development stage theory to identify China’s solar water heater industry in the early stages of commercialization to maturity stage, the current industry still needs state support. It is suggested that the government subsidize the socially disadvantaged groups to buy solar water heaters and subsidize the enterprises that have a certain scale of solar water heaters for environmental benefits.
