经济增长与日照减少:源自广东的实证研究

过去30年中国经济发展所取得的成绩举世瞩目,但生态环境污染日趋加剧亦成为不争的事实.作为中国现代化的缩影,1980-2010年,广东每增加1％的工业产值,日照时间减少0.3852小时.抽样调查的结果显示:目前广州、深圳等珠三角城市的日照时数已降至接近公众期望的临界值.遏制此种态势,转变经济发展模式固然重要,但更为重要的在于物欲的“零增长”.要做到这一点,日照时数应成为政府环保绩效评价的重要指标.

A Substantial Research on the Relevance between Economy Increase and Sunlit Time Decrease,Taken Guangdong as the Case

Of the past three decades,despite its huge economic achievements to which worldwide attention has been attracted,China’s environmental deterioration emerges to be an implausible issue.Between 1980 and 2010,Guangdong as an epitome of China’s modernization grew up every 1% in industrial output with satisfied sunlit duration of 0.3852 hours per year.The result showed that,at present,sunshine duration in Guangzhou,Shenzhen and other Pearl River delta cities has dropped to a critical level closing to the minimum level of public expectations.In order to reverse this trend,changing the mode of economic development is critically important.What’s more,"zero growth"of materialism greed would be more significant.To do that,sunshine duration should become an environmental indicator in government’s environmental performance evaluation system.
