中國共產黨建政8年後，就宣布完成全行業社會主義改造（1949-1956），實現了公有制與計畫經濟體制，取消了中國既有的混合經濟體制與私有財產制度。然而，自70年代末期開始，一連串試圖搞活經濟的措施開啟了中國經濟制度變化的序幕，30年來，中國已經由公有制計畫經濟體制，轉變到今日混合所有制市場經濟形態。 那些力量驅動了這場變化？那些變數與其交互作用影響，變化了經濟改革的方向？通過經濟制度變化的過程，那些成果帶來經濟制度走上不歸路的效用呢？這是筆者試圖解釋的課題。 事實上，中國經濟制度的變化，是一連串政權行動者「始料未及」的變化的結果，這場制度變遷─中國由公有制計畫經濟體制重新回到混合所有制市場經濟體制，一開始並未有指引變革行動的藍圖，變革的方向亦是在變化的過程上才漸次浮現的，它受到制度的限制，也受到偶發事件的影響，當然也就不意味是整體領導層的共識結果，它是在特定歷史結構與制度交錯相互影響下的產物。換句話說，是歷史（時間序列上的事件與變化）、制度與行動者組構了這場變遷。同時，這也是一場動態的變遷過程，變遷的路徑有來自制度遺產的影響，它也存在著路徑依賴的現象。 不過，路徑因行動者與制度安排的激勵而強化，從而實現變遷，但也在行動者基於觀念（意識形態）或利益下予以限制，從而轉折到不同的方向上。筆者認為，在中國獨特的政經體制下，路徑自我強化的現象不是內部自我激勵造成的結果，而是來自外部的因素；在路徑依賴的背後，制度結構與行動者的作用具有不容忽視的影響。 筆者認為，改變中國經濟制度最重要的取徑，就是「雙軌制」。「雙軌制」是一項行動者非意圖的創造，它始自陳雲倡議「摸著石頭過河」，獲得鄧小平的贊同，從而形成「試點」模式，並作為該模式的指導原則。 此外，觀念的引進與衝突是這場變化過程的重要部份，像是在推動「經濟特區試點政策過程中尤為明顯；當政權領導人受外部引入的觀念的影響，產生經濟特區政策，而領導人內部也因觀念的分歧，形成足以阻滯特區試點政策的衝突；他們之間的衝突（正統派vs改革派）貫穿整個變遷過程，這也正好說明了觀念因素在中國改變經濟制度過程上的重要影響。 / 8 years after the establishment of the People’s Republic of China, the Chinese Communist Party claimed that socialist reform has been successfully conducted. Public ownership and planned economy replaced mixed economy as well as private ownership. In the end of 1970s, however, a series of economic reform challenged public ownership with planned economy, which leads China enter into a mixed ownership economy. This thesis attempts to sort out the forces and consequences that drive economic reform. Through the transition of economic system, which leads China’s economy into a no return road. In fact, economic reform in China is an unexpected result by political regulators. Originally, it did not have a blueprint to lead the way. The direction from public ownership to mixed economy emerged throughout the reform, which is not a common consensus from the political leaders. Instead, it is dominated by history, political system as well as regulator in a dynamic way. This path dependency with institutional heritage character is the spot light of economic reform. The author claims the importance and direction of this reform is dominated by external factor. The most importance factor that change China’s economic is the launch of dual system. This system, with the slogan of “crossing the river by groping the stones along the way,” is proposed by CHEN Yun and approved by Deng Xiao-Ping. The introduction of concept is an important factor through the reform, which can be seemed from the process during the promotion of Special Economic Zones SEZs. When political regulators received outer concept and launched SEZs, internal diversity emerged that blocking the reform. Conflicts between orthodoxy and reformist can be seemed throughout reform period, influencing the forces and consequences of China’s economic system.

Text in Afrikaans / Summaries in Afrikaans and English / Miljoene mense ervaar voedselonsekerheid en een uit elke 50 hanger mense is woonagtig in Suid­ Afrika. Daar is genoeg voedsel op ons planeet om elke mens van 'n voldoende voorraad voedsel te verseker; dit waarborg egter nie voedselsekuriteit aan almal nie. Dit is die voedselparadoks: ondanks globale surplusproduksie van voedsel, ly miljoene mense wereldwyd aan wanvoeding en honger, maar veral in die ontwikkelende lande. Suid-Afrika is geen uitsondering nie en ten spyte van selfvoorsiening in voedsel, balanseer die voedselgelykstelling nie. Daar bestaan 'n ekstreme gaping tussen die produksie en verbruik van voedsel. Gevolglik is die probleem wat nagevors is in hierdie studie die gebrek aan voedselsekuriteit binne 'n wereldkonteks met voedselsurplusse en hoe dit reflekteer in Suid-Afrika. Teen hierdie agtergrond is daar 'n studie gedoen van die oorsake van voedselonsekerheid en die teoriee en verduidelikings van hongersnood. Die fokus van hierdie navorsingstudie is drieledig van aard. Eerstens fokus dit op 'n konseptuele ondersoek na hanger, armoede, voedselsekuriteit en hongersnood in Afrika. Tweedens is ondersoek ingestel na die oorsake vir die gebrek aan voedselsekuriteit in Afrika. Derdens is daar gefokus op Suid-Afrika en is 'n ondersoek gedoen na die voorkoms van hanger, wanvoeding, armoede en die nasionale konteks van voedselsekuriteit met die doel om vraagstukke daaromheen te identifiseer. Daar is bevind dat voedselsekuriteit bepaal word deur die beskikbaarheid van voedsel (aanbod) en die vermoe van mense om dit te bekom (aanvraag). Dit blyk dat die ontwikkelingsproses, regeringsbeleid, ekologiese omgewing en tegnologie, wetenskap en navorsing 'n direkte invloed het op die voedselsekuriteit van mense, en dat Suid-Afrika nie verskil van ander Afrikalande in hierdie verband nie. Hoewel Suid-Afrika voedselselfvoorsiening bereik het, ly miljoene mense honger weens armoede en die gebrek aan aansprake wat bydra tot 'n gebrek aan voedselsekuriteit. Die studie toon dat die Suid-Afrikaanse regering verskeie beleidsmaatreels in plek het ter bevordering van voedselsekuriteit, maar dat dit nie in die praktyk verwesenlik word nie. / Millions of people in the world experience food insecurity and one out ofevery 50 hungry people lives in South Africa. There is enough food on our planet to assure every person of an adequate supply of food; however, this does not guarantee food security for all. This is the food paradox: despite a global surplus production of food, millions of people experience malnutrition and hunger all over the world, but especially in the developing countries. South Africa is no exception and despite self-sufficiency in food, the food equation is not balanced. An extreme gap exists between the production and consumption of food. Consequently, the problem researched in this study is the lack of food security in a world context with surplus food and how this is reflected in South Africa. Against this background a study was undertaken of the causes of food insecurity and the theories and explanations of famine. The focus of this research study is threefold. Firstly it focuses on a conceptual enquiry intohunger, poverty, food security and famine in Africa. Secondly there is an enquiry into the causes of the lack of food security in Africa. Thirdly it focuses on South Africa and an enquiry is done into the incidence of hunger, malnutrition and poverty, and into the national context of food security with the aim of identifying relevant problems in food security. It was found that food security is determined by the availability of food (supply) and the capability of people to obtain it (demand). It appears that the development process, government policy, ecological environment and technology, science and research directly affect the food security of people, and that South Africa does not differ from other African countries in this regard. Although South Africa has achieved food self-sufficiency, millions of people experience hunger because of poverty and the lack of entitlements. The study shows that the South African government has various policy measures for the promotion of food security in place, but that food security does not materialise in practice. / Development Studies / D.Litt. et Phil.
