Democratic centralism is the main contentof the Marxist theory of Party building.As a fundamental organizing principle of Marxist party，Democratic centralism is the most fundamental systems of organization and leadership of our Party and country，and is an important part of the edifice of Marxist theory.Democratic centralism has been written into theCPCConstitutionandtheConstitutionofthePRC，it has turned into the Party and the Country's the fundamental organizing principle.In the Party's building history，democratic centralism has been maintained and improved continuously；In the whole country's political life，democratic centralism plays an increasingly prominent role.
Democratic centralism is our Party's fundamental organizational principlethat should be followed.Our Party is a unified，united，and combateffective Party.The most critical reason is that our Party has implemented democratic centralism organizational principle.Looking back over the history of the Party，the party's political life is normal and the party's cause is alive as long as democratic centralism is implemented smoothly.Otherwise the Party's cause will suffer setbacks and failures.The major mistakes which have occurred in the history of the Party are linked with democratic centralism being weakened and undermined.The fundamental reason of the Drastic Change of the East European Countries and the fall of the Soviet Union is that the Communist Parties in those countries have violated and given up the democratic centralism principle，and ultimately been defeated by hostile forces at home and abroad under attack from within and outside.According to the history，“if we fail to practice demo-cratic centralism satisfactorily，the Party，the state，socialism，the cadres and everyone may degenerate.”Therefore，it is a major topic that we can adhere to the principle of democratic centralism and carry out it or not effectively，and means their survival of the Party of the proletariat and the socialist regime.
Since the Third Plenary Session of the Eleventh Central Committee，our Party achieved great successes and accumulating rich experience in sticking to democratic centralism and consummating it.At the same time，Needless to say，there are still some problems in the course of the democratic centralism construction.For example，the theory of the building of democratic centralism is imperfect，the institution about democratic centralism is unsound，the Party's democratic centralism is implemented weakly and so on.Overall，the building of democratic centralism is still a long-term and arduous task and also is a systematic engineering.We should investigate and establish democratic centralism construction system covering all fields of it in order to adapt democratic centralism principle to the new situation and exert its institutional advantages in the changeable environment.
Based on this，this book which is named“Research on the Inner-Party's Democratic Centralism Construction of the Communist Party of China during the New Period”analyzed and studied democratic centralism from the following aspects under the guidance of“Three Represents”and the“Spirit of the Seventeenth and the Eighteenth and the Third Plenary Session of the Eighteen”and Comrade Xi Jinping's series of speech.
The book is divided into the following sections：
Introduction：The prologue makes a comprehensive introduction and generalization about this dissertation from its reason and significance of selecting this subject，research situation and literature review of democratic centralism construction，researching ideas and methods of this book，the main innovations and the emphasis，the difficulty about this book，some fundamental concepts of this book and so on.
PartⅠ：The proletarian revolutionary teachers dissertate ideology of democratic centralism construction.This thesis investigates our proletarian revolutionary teachers Marx，Engels，Lenin，Stalin and Comrade Mao's the basic idea on democratic centralism in detail from the process of development of democratic centralism in practice.These Thoughts are our theoretical foundation and precious spiritual wealth of building democratic centralism in the new era.The revolutionary teachers’statements on democratic centralism are of great importance on building democratic centralism，and still shine with brilliant light of theory.
PartⅡ：The important status and role of democratic centralism in the political life of our Party and state during the new period.Reviewing and rethinking revolutionary teachers’theory or practice of democratic centralism stimulate our thinking of importance of democratic centralism. Democratic centralism is playing a very important role in the political life of our Party and state.Democratic centralism not only is our Party and country's fundamental systems of organization and leadership，but also is our Party and country's organizational discipline and political discipline.Adhering to and improving democratic centralism concerns the Party's solidarity and unity and making a scientific decision，also has a bearing on the success of anti-corruption，while plays a vital role during the construction of socialist harmonious society and the Chinese dream of achieving great rejuvenation of the Chinese nation.
PartⅢ：Summarizing the new progress and experience from the building of democratic centralism in new era.Since the new era，our Party has explored and researched democratic centralism continually，made the great achievement and accumulated a plenty of experiences.This chapter will discuss the following two aspects.First，this thesis summarizes and dissertates theoretic contribution to democratic centralism construction in the new era made by three generation of collective leadership with Comrade Deng Xiaoping，Jiang Zemin，Hu Jintao，Xi Jinping as the core from connotation being developed，their awareness of building democratic centralism being enhanced，the system being improved constantly；Second，this thesis summarizes and generalizes the fundamental experiences from developing the inner-Party's democracy，upholding the centralized power and unity of the Party，improving collective leadership system and guarding against personal arbitrary，combating bureaucracy and anarchism，having a strong core of leadership，democratic centralism being followed and improved etc.
PartⅣ：Problems，tests and reasons of building democratic centralism This thesis attempts to summarize problems in the building of democratic centralism，such as the exercise of democratic centralism not being resolutely put into practice，the main weakness of cadre appointment and supervising system，indistinctly principal position of Party members，producing deviation in practical application of democratic centralism resulting from Party committee system and the system of leading cadres assuming responsibilities being confused，illusory democratic processes resulting from the incomplete working mechanism of democratic centralism，democratic centralism within the party supervision is not in place or absence etc，and analyses the causes of the existing problems mainly from ideological factor，realistic factor and the human factor.The aim is to get the root of the problems，and makes good bedding to put forward the countermeasures and suggestions.
PartⅤ：The countermeasures and suggestions of strengthening democratic centralism construction in the new era.This part is the focus of this book which explores the basic ideas from thought construction，organization construction，style construction，anti-corruption construction，system construction in the multi-faceted view of the“five parts”building of the Party.
Strengthening ideological construction is the prime objective of democratic centralism construction.Therefore，we must conduct education and training to the Party members and leading cadres in democratic centralism construction，and further strengthen the overall concept，responsible concept，discipline concept，service concept of the leadership cadres，and call for party members，leading cadres to continue to strengthen theoretical study，the aim is to lay the ideological foundation for carrying out and im-plementing democratic centralism better；Building a contingent of highcaliber leading cadres can provide organizational guarantee for democratic centralism construction.We should build up a huge contingent of party members and leading cadres who can implement democratic centralism effectively in practice，and establish a sound mechanism of selection，appointment，management and supervision，and cultivate their consciousness of democratic centralism；The party members and leading cadres must strengthen their aim consciousness and enhance party spirit continuously and develop the Party's three major styles：integrating theory with practice，maintaining close ties with the masses and making self-criticism. Building Party's excellent style can lay a solid foundation for democratic centralism；We should strengthen anti-corruption and build a clean government，and make unremitting ideological education to all our cadres，and promote inner-Party democracy fully，and make sure that our leading cadres are clean，honest and self-disciplined.Improving many specific systems can create a good institutional environment for democratic centralism implementation；Reforming and improving national congress system of CPC，the inner-Party electoral system，supervision system within the Party，the system of collective leadership，the Party member's rights guarantee system in our Party can provide institutional safeguards for the correct implementation of the principle of democratic centralism.
Epilogue：This section is a brief review and summary about the thesis，and puts forward some perspectives to build the inner-Party democratic centralism.For the Communist Party of China，she is a ninety-three year old and is in the saddle in China for sixty-five years.Although we has gone through difficulties and setbacks in the inner-Party's democratic centralism construction，our party has gainned rich experience of democratic centralism and builded the basic institutional framework of democratic centralism which is commendable！In the new century and new stage，we are filled with confidence.We firmly believe that if we have remained a collective leadership with Comrade Xi Jinping as the core and kept pace with the times and innovated in theory and system and practice，our Party's democratic centralism construction is bound to achieve long-term development，it will greatly promote the realization of the goal of the Party's construction.
