Content overview China's LED lighting export prosperity index in December was 52. 9. It is in the economic zone, with an increase of 1 point over the previous month. The prosperity of LED lighting exports has reached the excellent state in 2017, this is mainly affected by multiple factors such as China's LED lighting export scale, exchange rate fluctuations, price trend of packaged devices, and enterprise LED lighting export business revenue. High-tech LED lighting export monthly prosperity index high-tech LED Research Institute (GGII) Compilation, remarks: all indexes are in the range of 40 ~ Between 60 and 50 is the critical value of the prosperity index. When the prosperity index is greater than the critical value, it indicates that the economic situation tends to rise or improve and is in a state of prosperity; When the prosperity index is less than the critical value, it indicates that the economic situation tends to decline or deteriorate and is in a sluggish state. The specific classification criteria are: 58 or more is a very prosperous interval, which is a depressed interval ,(47,42]For a relatively sluggish range ,(42,40]It is a very sluggish range. Second, GGII analyzed the growth of export scale index, and the overall growth of exports has become stronger. In December, the total amount of China's LED lighting exports was 23. US $7. 5 billion, up year-on-year; The number of exports is about 20. 2. 2 billion, up 24 year-on-year; The scale index increased by 3 percentage points from the previous month. The exchange rate index did not fluctuate significantly and did not have a significant negative impact on the export situation. In December, the exchange rate of the US dollar against the RMB fell by 0. 4. It has not brought a strong negative correlation to the development trend of LED lighting exports. LED raw material index is stable, and the price of packaged devices tends to be stable. In terms of LED packaging, in December 2017, the prices of mainstream LED packaging devices in the Chinese market remained stable, with no obvious fluctuations in high-power and medium-power products, but the prices of packaging products are expected to be lowered from the first quarter of 2018. Under the stable price, manufacturers continue to upgrade product performance, and focus on the development of industrial lighting, outdoor lighting and other markets with high growth rate. The revenue index of LED lighting export business of enterprises has increased, and the export scale of mainstream enterprises has increased. In December, the revenue index of LED lighting export business of enterprises increased by 6 percentage points from the previous month, and about 1500 production enterprises showed different degrees of growth. List of growth of China's LED lighting mainstream enterprises in December 2017, remarks: This data statistics only considers the data of production enterprises directly declared for export.
