china's dilemma between pursing higher economics growth and escalating pollutions due to the industrialisation

The Chinese economy has performed admirably since reforms commenced with the decisions of the Eleventh Party Congress in 1978.  The successful effects of the reforms were clearly evident through the mid-eighties to the early nineties, as reflected in the nation’s double digit GDP growth.  In contrast to the experience in neighboring India, China has also succeeded in its efforts to reduce poverty during the period between 1978 and 1988.   Over that ten year period China reduced the number of people living below the official poverty line from 570 million to 220 million while India’s figure remained at 400 million.  Why did the Chinese economy perform as well as it did throughout the early stages of reform as compared to India?  A major factor may be that foreign-direct investment (FDI) over this period in China amounted to 261 billion dollars (20 times the FDI directed towards India).  China’s accumulated FDI in 1998 represented 25% of GDP.  However, FDI is currently shrinking and not expanding in China.  China’s economy is slowing down and the reasons for this trend are unclear. 

One explanation may be that China accomplished the easier economic reforms during the early 1980s.   During this period, China opened up its economy to FDI and promoted export led growth.   In more recent years, however, Beijing has been forced to deal  with the more difficult challenges posed by price deflation, a troubled banking system, falling corporate profits, shrinking export growth and declining FDI.  That China’s economic planners have to deal with some very daunting tasks is reflected in the following statistics:
 -         Export growth during 1998 was almost 0% in contrast to the 1997 figure of 21%.  This was the worst trade performance in fifteen years.
-         Two-thirds of China’s export surplus disappeared during the first half of 1999, although third quarter data show exports starting to rise.
-         During China’s dramatic period of growth, the trade front provided fuel for the economic engine.  This situation no longer holds true.

For years Beijing has tried to ignore market forces and command economic growth through Soviet-style central planning.  It urged state owned enterprises to produce goods without regard to whether they were marketable or not—and often they were not.  In February 1999 Beijing announced that two thirds of its key manufactured foods were in oversupply.  In addition to the difficulties mentioned previously, China is now facing rising unemployment and social unrest. Beijing’s fears over social unrest stalled attempts at deepening economic reforms during most of 1999.  The leadership is on the horns of a dilemma.  It must slow down any economic reform that radically worsens unemployment.  Yet if it slows down economic growth the leadership may be destroying one of the pillars of its own legitimacy. Seven percent GDP growth may not be high enough when viewed in the Chinese context to keep the lid on the pot of China’s boiling economic and social difficulties.  China needs at least an eight percent growth rate to outpace population growth and ensure positive per capita growth.  China’s real GDP growth has fallen from 13% in 1994 to about 6% in 1999.  Another reason for this reduction in growth is the shortfall in aggregate demand.  Consumers are reluctant to spend due to fear of losing their jobs and are saving money to offset the reduction in state subsidies.

The government has initiated a number of steps to deal with these looming problems.  It has increased government spending to offset consumer demand shortfalls.  This short-term fix is probably not sustainable.   It is uncertain how long the government can invest in “make work” programs when money is also required to service the debt, re-capitalize insolvent state banks and establish a new pension system to replace the one that is dissolving as the state divests itself of SOEs.  Consequently the pressure for devaluation is increasing.  Beijing will likely determine that preventing excessive or disruptive unemployment is its highest priority.   Social stability and availability of jobs are far more critical to Beijing’s hold on power than any other factors.  How should the leadership deal with its revenue shortfall?  Certainly it could raise taxes, but this no doubt would worsen aggregate demand.  Perhaps China’s best course of action is to scrap Central Bank control of capital markets and opt for a Western style long- term bond market.  Moreover, entry to the WTO may boost aggregate demand, foster free competition, pave the way for further economic reforms, and reduce capital flight. 

Any degree of fragmentation or instability in China caused by economic difficulties will affect the region.  It is in the interests of China’s neighbors to provide the capital and expertise as well as lend any cooperation they can as China finally begins to tackle its fundamental economic challenges.

As China develops its economy, it requires ever greater supplies of energy.  Many observers believe that energy will be one of the most serious challenges for China in the 21st century.  Currently, China relies heavily on fossil fuels for its energy supplies, with coal serving a primary role.  Other sources of energy include oil and natural gas.   Despite its possession of vast energy supplies—especially coal—China is expected to experience energy shortfalls in the next few decades.  The gap between energy demand and supply may be as large as 140 million tons of coal.   For China, the most obvious solution is to rely even more extensively on coal.  However, in the long term, questions are arising about whether such a strategy is sustainable.  Coal contributes substantially to China’s air pollution.  It also contributes to acid rain, a problem that is regional and not simply limited to China.  Finally, greater use of coal will ensure that China will be responsible for a greater proportion of the world’s carbon emissions, a factor linked to global warming and climate change.  Given these challenges, the question that emerges is: is there an alternative?
One way that China could meet its growing energy demand is by emphasizing efficient use of energy.  Although efficiency has improved in the past several decades, it lags behind advanced industrialized countries substantially and thus the margin for improvement is substantial.  Another alternative might be greater reliance on natural gas which is a much cleaner form of alternative energy.  China has about 33 trillion cubic meters of natural gas of which only 3 trillion cubic meters have been prospected thus far. 

The industrial SO2 emissions mainly found in coal consumption are the leading cause of urban air pollution observed in most of the Chinese cities. The freer trade stimulates the rapid urban growth
resulting in a staggering expansion of heavy industry and urbanization that requires colossal inputs of energy, almost all from coal that is the most readily available but the dirtiest. The coal consumption has been more than quadrupled since 1980, reaching nearly 2.81 billion tons of
standard coal equivalents (SCE) in 2008 . The industrial sources (mining, manufacturing, and utilities) were responsible for 85.8 percent of the reported SO2 emissions with electricity generation accounting for 45.7 percent (China Statistical Yearbook 2009).1 Despite the
government’s efforts to improve fuel quality and to relocate some heavily polluted industrial activities, the industrial SO2 emissions have been still increasing because of the increasing share of coal consumption in power generation and the lack of emissions control in the massive number of small furnaces and kilns (especially those operated by township and village industrial
enterprises)

The economic activities of production and consumption require the use of energy, and the use of energy affects the environment in the forms of water pollution and air pollution


Air Pollution
The air and water in China, especially in the urban areas, are among the most polluted in the world. According to a report of the World Health Organization (WHO) in 1998, of the ten most polluted cities in the world, seven can be found in China. Sulfur dioxide and soot caused by coal combustion are two major air pollutants, resulting in the formation of acid rain, which now falls on about 30% of China's total land area. Industrial boilers and furnaces consume almost half of China's coal and are the largest sources of urban air pollution. The burning of coal for cooking and heating in many cities accounts for the rest. 

Another major source of air pollution is the use of oil and gasoline in the transportation sector, especially the emission from automobiles and jet engines. As the country becomes industrialized, pollution from both industrial and consumer sources will increase because of higher levels of output and consumption, the latter including the increase in the use of automobiles and in air travel, unless pollution per unit of output or consumption can be reduced. See Committee on Energy Futures and Air Pollution in Urban China, et. al. (2007) for more information on the state of and policies for urban air pollution in China.

 Water Pollution
Mercury released into the air by coal-fired power plants is captured by raindrops, and transferred to the soil, surface water and groundwater. Surface water affects the fish consumed. Groundwater is polluted by runoff from factories, smelters and mining operations, and then used by farmers downstream to irrigate their crops. Heavy use of fertilizers has contributed to contamination also. Fertilizers in China often contain high levels of metals, especially cadmium, which is harmful.

China’s water is polluted also by the disposal of waste. There have been large quantities of deposits of organic and toxic waste from households, agriculture and industry.
Deforestation has caused the flow of bud along the rivers and affects water supply and quality. People’s Daily, June 12, 2007 reports that Lake Taihu was covered with a foul-smelling algae and freshwater was shut off for more than 2 million people in Wuxi due to the blue-algae infestation of the lake.

Besides the poor quality of water there is the problem of the shortage of water.  Water beds of several important cities including Beijing and Shanghai are low, causing shortage of supply of well water. Supply of waters from rivers including the Yellow River and the Yangtze River are running short because of diversion to agriculture production and electricity generation along the sources.

 Even though an increase in china's economy would increase the standard of living for the people in china but  i personally think that china should not risk china's environment and the well-being of the people just for china's economy. i think china should moderate the amount of industries and energy consumption so that the welfare of the people would be threatened.
