That is a very dangerous assumption to base judging the management on. Dividends alone don't tell the whole picture.
Firstly, one of the drivers of a firm's dividend is financial obligation. To cut things short, a firm can essentially pay out dividends by borrowing. The other way to look at it, is that a firm can also liquidate assets to pay dividends. Should a firm be liquidating profitable assets that can continue to generate wealth and shareholder value for the sake of satisfying the need to look good paying dividends? Conversely, the question is also, should a firm really be borrowing to pay dividends?
Next, a firm that doesn't pay dividends might not necessarily indicate incompetent management. It really depends on the industry the firm is operating in. Growth companies or companies operating in industries that are not mature are expected to grow by re-investing profits. This can be in the form of acquisitions to consolidate it's position within the industry to secure profits in the longer term. Or it can also be to undertake projects that generate value for shareholders. If this is so, should investors and management be penny wise pound foolish to be fixated on the penny (dividend) over the pound (more profits over time)?
Finally, if you are investing in non-sg stocks as mentioned earlier, there are reasons why firms in other countries such as US might decide not to pay dividends. There are other ways to distribute to shareholders, such as share buybacks.

"Plus, no dividend may also means that the report could be fake and just a means to hide the true from shareholders and the authorities."
Just to add on, the above methods I mentioned about how firms can pay dividends while destroying shareholder value at the same time, are legal. Publishing a fake report on the other hand is illegal. With the 2 options, which do you think firms will likely choose?
