Most of the issues that western development has to tackle are non-institutional and non-technical ones that can be fundamentally solved through downsizing . We should adhere tothe principle of "having Do's and Don'ts" , shifting from the guiding ideology of "problem-solution type" to that of "solution-problemtype" , carrying out policy coordination andintegrative decision-making to optimize the overall policy effect , and seeking "solution within the system" while downsizing population and trying to avoid the transfer of crisis to nature in the campaign of anti-poverty .
