South Korea's Samsung Electronics said it is considering lifting its 2014 dividend payout by up to 50%, its latest attempt to boost its share price in a year plagued by disappointing earnings. 

The world's biggest smartphone maker said in a regulatory filing that it is actively considering a "special increase" in dividend of between 30-50%. 

Its board will decide the year-end dividend amount in January, and seek approval at its annual shareholder meeting, set for March. 

The announcement comes amid mounting pressure for the tech giant to return more capital to investors as it heads for its worst annual profit in three years, hit by a falling share of the global smartphone market.

Explaining its move, the company said it wants to increase shareholder value, as well as contribute to revitalising the South Korean economy. 

The firm's stock has recovered from a multi-year low hit in October, thanks to the company's November announcement of a $2 billion share buyback plan. But shares are still down 3.2% for the year. 

Samsung Electronics said in January of this year that it would significantly increase dividend payouts in 2014, though in July it kept the interim dividend unchanged from a year earlier. 

The firm's total 2013 dividend payout was about 2.2 trillion won, including a year-end dividend of 13,800 won per share.
