It is known that the graph of the function $y= \frac {1}{x}$ has its center of symmetry at $(0,0)$, the graph of the function $y= \frac {1}{x}+ \frac {1}{x+1}$ has its center of symmetry at $\left(- \frac {1}{2},0\right)$, and the graph of the function $y= \frac {1}{x}+ \frac {1}{x+1}+ \frac {1}{x+2}$ has its center of symmetry at $(-1,0)$. From this, it is inferred that the center of symmetry of the graph of the function $y= \frac {x+1}{x}+ \frac {x+2}{x+1}+ \frac {x+3}{x+2}+…+ \frac {x+2019}{x+2018}$ is \_\_\_\_\_\_.
