It has been issued following allegations made by Azeem Rafiq and a number of other players.
The five-point plan has "12 tangible actions", while the England and Wales Cricket Board (ECB) has pledged £25m over five years.
The ECB will also form a new anti-discrimination unit within six months.
Last week, former Yorkshire spinner Rafiq told a Digital, Culture, Media & Sport select committee the English game is "institutionally racist".
Rafiq's allegations against the county have been echoed by former academy player Irfan Amjad and another anonymous player.
Jahid Ahmed, Maurice Chambers and Zoheb Sharif have also made claims about their time with Essex.
Sports minister Nigel Huddleston said the government could take the "nuclear option" of creating an independent regulator if the ECB does not "put its house in order" over racism.
"The last few weeks have been very, very tough," said ECB chief executive Tom Harrison. "It feels like an earthquake has hit us.
"Our game has been portrayed in the worst possible way in the world's media. Azeem's testimony and testimony from others has revealed serious issues which we have collectively not dealt with for many decades.
"There are clearly large numbers of people in the country who feel like cricket has not been there for them. This is our latest attempt to say we are listening and we are desperate to solve the problem."
The action plan, jointly published by the ECB, Marylebone Cricket Club (MCC), Professional Cricketers' Association, 41 counties, women's regions and recreational network is described as a "game-wide response to discrimination".
The 12 actions each fall under one of the five points, as follows:
* Listen, care and educate - the setting up of of a standardised approach to handling complaints, promoting the aims of the Independent Commission for Equity in Cricket and providing all who work in cricket with ongoing Equality, Diversity and Inclusion (EDI) education.
* Address dressing-room culture - publish a full review of dressing-room culture in all professional teams, reassess player and coach education.
* Remove barriers in the talent pathway - improve support for people from diverse backgrounds, identify talent from non-traditional backgrounds and take action towards reaching a minimum 20% gender diversity and appropriate level of ethnic diversity.
* Create welcoming environments for all - full-scale review into crowd behaviour at professional matches, ensure venues are welcoming to all faiths and cultures, upgrade education in recreational cricket.
*Publish localised action plans within six months - each organisation will deliver board diversity (30% female, representative ethnicity) by April 2022, adopt an anonymised recruitment tool for all senior roles, every senior executive in the game to have personalised EDI objectives.
Harrison could not confirm who will lead the review into dressing-room culture, which will look at every professional men's and women's team in the country.
ECB central funding could be withheld where EDI minimum standards are not met, the governing body said.
