Excavators are the first step in infrastructure investment.

Whether it is railway, port, power station, power transmission and transformation, oil and gas transmission projects, are closely related to the development of "shovel-shovel-shovel".

The aircraft's market sales have become a microscopic window into fixed asset investment.

Data from mining Machinery Branch of China Construction Machinery Industry Association shows that from January to June this year, 25 manufacturers were included in the statistics, with a total of more than 120,000 pieces of mining machinery products, a year-on-year increase of 60%.

Wenbin, chief researcher of China Minsheng Bank, believes that the growth of excavator sales is closely related to the growth of real estate development investment.

Investment in real estate development has maintained rapid growth.

In the first five months of this year, investment in real estate development increased by 10.2 percent year-on-year, 3.2 percentage points higher than that at the end of last year.

The increase in excavator sales reflects an increase in public infrastructure construction, according to Shi Lei, director of the Public Economy Research Center of Fudan University.

The increase in sales of mechanical excavators mainly reflects the increase in public infrastructure construction.

This is related to the rural revitalization strategy and the new round of urban and rural road infrastructure renovation.

The early "village-to-village" and "village-to-township" projects have entered the cycle of renewal and renovation, and the intensity of project renovation has been enhanced.

First, investment in construction machinery has increased.

The production of major products in the construction machinery industry will be released from January to September 2018, according to the report on Oct 26.

According to statistics, in September 2018, excavator production in China was 19,655,12,806 tons of loaders and 4,7667.2 tons of cement equipment, up 48.1%, 17.6% and 18.3%, respectively. The output of compaction machinery was 4,189 units, down 1.7% year-on-year in Taiwan.

In September 2018, China's output of excavators, loaders and mud equipment was 19,655, 12,806 and 4,7667.2 tons, up 48.1%, 17.6% and 18.3%, respectively. The output of compaction machinery was 4,189, down 1.7% year on year.

From January to September, the cumulative output of excavators, loaders, compacting machinery and cement equipment was 194,153, 108,324, 45,786 and 411,868 tons, up by 51.7%, 26%, 17.9% and 7.5%, respectively.
