Recently, the national bureau of statistics released the 2017 industrial enterprises situation, according to the national industrial enterprises above designated size total profit of 7.51871 trillion yuan, up 21% from a year earlier, grow faster in 2016 than 12.5%, the highest growth rate since 2012 years. Industry insiders believe that this data reflects the significant improvement in the operating efficiency of China's industrial enterprises last year, the further improvement in operation quality and the obvious effect of the supply-side structural reform in the industrial sector. This year, the increase in earnings of industrial enterprises is in the middle reaches of manufacturing. Productivity, deleveraging, and cost reduction are evident in the industry, with most industry profits rising. In 2017, 37 of the 41 industrial sectors saw profit increase over the previous year, eight more than in the previous year. Mining profits rose from a decline of 2.6 times in 2017. Manufacturing profits were up 18.2 per cent, accelerating 5.9 percentage points faster than in 2016. High-tech manufacturing profits grew 20.3 per cent, faster than other manufacturing sectors. Chinese academy of social sciences industrial economy research institute of industrial operation room, deputy director of the original lei, said in an interview with international business newspaper reporter data reflected in China in 2017 to promote the supply side structural reforms achieved positive results, capacity and leverage, cost reduction, etc. To effectively implement policies. National bureau of statistics, note the researchers, when reading data, industrial SiHePing with supply side structural reform deepening, the key areas of industrial reform tasks in 2017 achieved significant results were mainly reflected in several aspects: one is to capacity made positive progress. The production capacity of steel and coal has improved the supply quality, raised the price of products, and the enterprise benefits have rebounded sharply. The second is that leverage has declined. At the end of 2017, the asset-liability ratio of the above industrial enterprises is 55.5%, which is 0.6 percentage points lower than that of the previous year. Third, the cost of enterprises continues to decline. He ping said that the next stage, will continue to unswervingly deepen structural reforms, supply side new economic development, unswervingly to speed up the industry move steadily from the industrial economy high speed development to quality development. Improve profit increment in middle manufacturing Guotai junan, chief economist at changchun thinks, from the structure, improve corporate earnings growth this year will appear from the upstream to the middle reaches of the industry chain transmission, incremental mainly in the middle of manufacturing. The company further explained that improved corporate earnings this year will boost equipment investment spending. Currently, earnings growth remain high, be helpful for enterprises to promote "technical" and equipment upgrading, which will promote the rise in demand for middle related manufacturing equipment, and then bring the improvement of relevant industry revenue and profit. Moreover, the trend of continuous improvement in profit growth of high-end manufacturing industry has already appeared. Although the traditional industrial products industry, such as black metal CaiXuanYe, non-ferrous metal CaiXuanYe, oil, coal and other processing industry profit growth to achieve a higher level, but affected by industrial products price growth is slowing, slowing growth in recent months. Traditional upstream industry profits, therefore, are susceptible to price factor disturbance, the sustainability of profits improve trend and high-end manufacturing, new kinetic energy endogenous role in economy, this year is expected to keep growing.
