Vittorio De Sica's Bicycle Thieves references?

I just thought, the plot is so similar to Bicycle Thieves

http://www.imdb.com/title/tt0040522/

Of course that is not the only film with a similar plot, there is also

Xich lo

http://www.imdb.com/title/tt0112767/

But I was just thinking the idea of getting the main tool of work stolen, and the desperation of Guai is so similar to that of the father in the Bicycle thieves do resemble a lot. I wondered of the director has seen the other film and treated is as an inspiration.
